These ancient opossums have been separated generically from Didelphys (in its widest sense) on account of certain differences in the relative sizes of the lower premolars, but as nearly the whole of the species have been formed .on lower jaws, of which some hundreds have been found, it is impossible to judge how far these differences are correlated with other dental or osteological characters.
Besides these interesting European fossils, a certain number of didelphian bones have been found in the caves of Brazil, but these are either closely allied to or identical with the species now living in the same region.
Under the heading of Multituberculata will be found a brief account of certain extinct mammals from the Mesozoic formations of Europe and North America which have been regarded as more or less nearly related to the monotremes.
The oppression of Antiochus led to a revolt of the Jews under the leadership of the Maccabees, and Judas Maccabaeus succeeded in capturing Jerusalem after severe fighting, but could not get The sites shown on the plan are tentative, and cannot be regarded as certain; see Nehemiah ii.
Ctesias must certainly have known of it, and it is possible that he may have named it simply IIEpvac, after the people, as is undoubtedly done by certain writers of a somewhat later date.'
But this certainly was not the leading point of view with the mass of the Rabbins; 1 and at any rate it is quite certain that the synagogue is a post-exilic institution, and therefore that the Sabbath in old Israel must have been entirely different from the Sabbath of the Scribes.
What is certain is that the origin of the Sabbath must be sought within a circle that used the week as a division of time.
They did not dedicate each day in turn to its astrological planet; and it is therefore precarious to assume that the Sabbath was in its origin what it is in the astrological week, the day sacred to Saturn, and that its observance is to be derived from an ancient Hebrew worship of that planet.4 The week, however, is found in various parts of the world in a form that has nothing to do with astrology or the seven planets, and with such a distribution as to make it pretty certain that it had no artificial origin, but suggested itself independently, and for natural reasons, to different races.
The Babylonian calendars contain explicit directions for the observance of abstention from certain secular acts on certain days which forms a close parallel to the Jewish Sabbatical rules.
And there is a marked contrast in style between these statues and the certain works of Pheidias.
Whatever the racial affinities of the early inhabitants may have been, it is certain that in historic times Rhodes was occupied by a Dorian population, reputed to have emigrated mainly from Argos subsequently to the "Dorian invasion" of Greece.
Forbes drew attention to a certain community amongst birds and other vertebrates, invertebrates, and amongst plants, on all the lands stretching towards the south pole.
No certain cure has been or is likely to be discovered for their poison, but in less serious cases strychnine has been used with advantage.
One thing is certain, that there is in Australia a flora that is a remnant of a vegetation once widely distributed.
Religious instruction is not imparted by the state-paid teachers in any state, though in certain states persons duly authorized by the religious organizations are allowed to give religious instruction to children of their own denomination where the parents' consent has been obtained.
This conference adopted an address to the queen expressing its loyalty and attachment, and submitting certain resolutions which affirmed the desirability of an early union, under the crown, of the Australasian colonies, on principles just to all, and provided that the remoter Australasian colonies should be entitled to admission upon terms to be afterwards agreed upon, and that steps should be taken for the appointment of delegates to a national Australasian convention, to consider and report upon an adequate scheme for a federal convention.
Under this act the appropriation of these surplus funds to certain trust purposes in the Federal treasury is held to be equivalent to payment to the states.
Worthy of special note are canon 33, enjoining celibacy upon all clerics and all who minister at the altar (the most ancient canon of celibacy); canon 36, forbidding pictures in churches; canon 38, permitting lay baptism under certain conditions; and canon 53, forbidding one bishop to restore a person excommunicated by another.
A short time afterwards Artabanus was deposed again, and a certain Cinnamus was proclaimed king.
Mehemet Ali, who was the viceroy of Egypt, owed his position, to a certain extent, to the recommendations made in his behalf to the French government by Mathieu de Lesseps, who was consul-general in Egypt when Mehemet Ali was a simple colonel.
Straw-plaiting is a considerable industry at Lacco; and a certain amount of fishing is also done.
To a certain extent these works embody the more important discoveries of their author.
A second great service was the publication in the British Association Reports for 1833 of his "Report on the Recent Progress and Present State of certain branches of Analysis."
But his efforts were already doomed to certain failure.
In anti-religious materialism the motive is hostility to established dogmas which are connected, in the Christian system especially, with certain forms of spiritual doctrine.
The animal is in a certain sense, indeed, the food of the god.
Whether the division of the lobus dexter into two divisions - (i) lobus dexter proper and (2) lobus quadratus, as in modern anatomical nomenclature - was also assumed in Babylonian hepatoscopy, is not certain, but the groove separating the right lobe into two sections - the fossa venae umbilicalis - was recognized and distinguished by the designation of "river of the liver."
The metallic glitter of avanturine or sun-stone (q.v.) is due to the enclosed scales of gothite and certain other minerals.
On account of this, it has been suggested that in a forgotten past the Sakai were themselves the fashioners of the stone implements, and certain it is that all tools which have no representatives among the stone kelts are known to the Sakai by obvious corruptions of their Malayan names.
The salt-houses were divided between the king, the earl of Chester and certain resident freemen of the neighbourhood.
As the recognized leader of the new party, his nomination by the Republicans for the presidency in 1856 and in 1860 was regarded as certain; but in each instance he was put aside for another.
Both these oaks grow well in British plantations, where their bright autumn foliage, though seldom so decided in tint as in their native woods, gives them a certain picturesque value.
He declared, when answering a complaint that a certain captain in his regiment was a better preacher than fighter, that he who prayed best would fight best, and that he knew nothing could" give the like courage and confidence as the knowledge of God in Christ will."The superiority of these men - more intelligent than the common soldiers, better disciplined, better trained, better armed, excellent horsemen and fighting for a great cause - not only over the other parliamentary troops but over the royalists, was soon observed in battle.
There are also certain liabilities or debts which, for the convenience of the remedy, have been made to appear as though they sprang from contract, and are sometimes termed quasi-contracts.
In the United States imprisonment for debt was universal under the common law, but it has been abolished in every state, except in certain cases, as where there is any suspicion of fraud or where the debtor has an intention of removing out of the state to avoid his debts.
Even the prologues, which later researches have shown to be in the main by the hand of Plautus himself, though certain passages were clearly added at a later date, e.g.
His command of the art is such that his plays read like original works, and it may be at least said that some of his characters stand out so vividly from his canvas that they have ever since served as representatives of certain types of humanity, e.g.
The earliest recorded count of Dammartin was a certain Hugh, who made himself master of the town in the 10th century; but his dynasty was replaced by another family in the 11th century.
If we raise i lb of matter through a foot we do a certain amount of work against the earth's attraction; if we raise 2 lb through the same height we do twice this amount of work, and so on.
All we can do in such cases is to place the system under certain conditions of transformation, and be content with the amount of work which it is, as it were, willing to render up under those conditions.
An intelligent creature, or "demon," possessed of unlimited powers of vision, is placed in charge of each door, with instructions to open the door whenever a particle in A comes towards it with more than a certain velocity V, and to keep it closed against all particles in A moving with less than this velocity, but, on the other hand, to open the door whenever a particle in B approaches it with less than a certain velocity v, which is not greater than V, and to keep it closed against all particles in B moving with a greater velocity than this.
Fichte's general views on philosophy seem to have changed considerably as he advanced in years, and his influence has been impaired by certain inconsistencies and an appearance of eclecticism, which is strengthened by his predominantly historical treatment of problems, his desire to include divergent systems within his own, and his conciliatory tone.
Yet there is a certain difference between this and the work of a poor artist whose designs are threadbare.
But it is equally certain that the pure violoncello tone in large masses belongs to a distinctly different region of orchestral effect.
This could be fixed, within certain limits, at whatever pitch suited the composition; but on the horn it could be only very partially filled out by notes of a muffled quality produced by inserting the hand into the bell of the instrument, a device impossible on the trumpet.
At present we can only be certain that the criterion according to which Brahms, being a symphonic writer, has no mastery of orchestration whatever, is not a criterion compatible with any sense of symphonic style.
While the majority of the Nematodes are parasites, there are many that are never at any period of their life parasitic. These free-living forms are found everywhere - in salt and fresh water, in damp earth and moss, and among decaying substances; they are always minute in size, and like many other lower forms of life, are capable of retaining their vitality for a long period even when dried, which accounts for their wide distribution; this faculty is also possessed by certain of the parasitic Nematodes, especially by those which lead a free existence during a part of their life-cycle.
The females produce thousands of larvae, which circulate in the blood, and show a certain periodicity in their appearance, being much more numerous in the blood at night than during the day.
The speed of these two motions depends much on the length of the span and of the longitudinal run, and on the nature of the work to be done; in certain cases, e.g.
On arriving at a certain height the lift ceases and the jenny is released, and by the continued pull of the rope, it runs up the jib; on arriving at an adjustable stop, the jenny is again locked, and the load can be lowered out; the hook can then be raised, when the jenny is automatically unlocked, and on paying out the rope the jenny gravitates to its first position, when the load is lowered and the cycle repeated.
Later, a horseman was due from certain areas.
The Code regulates the feudal position of certain classes.
As the city grew, the right to so many days a year atone or other shrine (or its " gate ") descended in certain families and became a species of property which could be pledged, rented or shared within the family, but not alienated.
But vestals, hierodules, certain palace officials and slaves had no rights over their children and could raise no obstacle.
Nearly all the cable companies possess their own steamers, of sufficient dimensions and specially equipped for making ordinary repairs; but for exceptional cases, where a considerable quantity of new cable may have to be inserted, it may be necessary to charter the services of one of the larger vessels owned by a cable-manufacturing company, at a certain sum per day, which may well reach £200 to £300.
This allowed a shorter train and stronger wheelwork to be used, securing more certain action, and involving less risk of derangement.
Each channel consists of a keyboard and receiver both electrically connected to certain parts of the distributor.
At regular intervals a rotating arm on the distributor connects the five keys of each keyboard to line, thus passing the signals to the distant station, where they pass through the distributor and certain relays which repeat the currents corresponding to the depressed keys and actuate electromagnets in the receivers.
The Baudot apparatus can have certain channels extended so as to form a means of continuous communication between one station and two or three others by means of one line.
In the Rowland multiple method of telegraphic working, the transmitter consists of a mechanical keyboard provided with a series of levers, which effect certain combinations of positive and negative currents for each letter.
The submarine telegraphs are mainly controlled by companies, the amount of issued capital of the existing British telegraph companies (twenty-four in number) being £3 0, 447, 1 9 1, but a certain number of lines are in government hands.
This form of electric wave detector proved itself to be far more certain in operation and sensitive than anything previously invented.
Marconi, however, made the important discovery that if his sensitive tube or coherer had one terminal attached to a metal plate lying on the earth, or buried in it, and the other to an insulated plate elevated at a height above the ground, it could detect the presence of very feeble electric waves of a certain kind originating at a great distance.
At the receiving station Marconi connected a single voltaic cell B 1 and a sensitive telegraphic relay R in series with his tube of metallic filings C, and interposed certain little coils called choking coils.
In addition he added certain spark-generating coils across the contacts of the relay and tapper.
In series with the tube is placed a single voltaic cell and a telegraphic relay, and Marconi added certain coils placed across the spark contacts of the relay to prevent the local sparks affecting the coherer.
Very briefly stated, his method consists in sending out a group of wave trains at certain irregular but assigned intervals of time to constitute the simplest signal equivalent to a dot in the Morse code, and a sequence of such trains, say three following one another, to constitute the dash on the Morse code.
A problem of great importance in connexion with electric wave telegraphy is that of limiting the radiation to certain directions.
In his method three vertical antennae are employed, placed at equidistant distances, and oscillations are created in the three with a certain relative difference of phase.
Duddell discovered in 1900 that if a continuous current carbon arc had its carbon electrodes connected by a condenser in series with an inductance, then under certain conditions oscillations were excited in this condenser circuit which appeared to be continuous.
Increase in the voltage acting upon a solid conductor increases the current through it, but in the case of the electric arc an increase in current is accompanied by a fall in the difference of potential of the carbons, within certain limits, and the arc has therefore been said to possess a negative resistance.'
But even in the earlier group certain variations appear.
The receiver was based on the change of friction produced by the passage of an electric current through the point of contact of certain substances in relative motion.
When the subscribers in a local area exceed a certain number, or when for some other reason it is not convenient or economical to connect all the subscribers in the area to one exchange, it is usual to divide the area into a number of districts in each of which an exchange is placed, and to connect these district exchanges together by means of " junction circuits."
Several single switchboards like that described may be employed, each devoted to a certain section of the subscribers, and placed in care of an operator.
Each subscriber's circuit is further connected to another spring-jack directly associated with the calling-drop. These springjacks, known as answering jacks, are distributed along the switchboard, a certain number being terminated upon each position and placed in the care of the operator assigned to that position.
The subscriber pays a fixed annual rent which covers a certain number of free out - ward calls, say boo; additional calls he purchases in advance in blocks of several hundred at so much per hundred, the price being reduced as the number increases.
The service has since been extended to certain other English provincial towns; and the Anglo-Belgian telephone service has similarly been extended.
Hesse-Nassau was formed in 1867-1868 out of the territories which accrued to Prussia after the war of 1866, namely, the landgraviate of Hesse-Cassel and the duchy of Nassau, in addition to the greater part of the territory of Frankfort-on-Main, parts of the grand-duchy of Hesse, the territory of Homburg and the countship of HesseHomburg, together with certain small districts which belonged to Bavaria.
He seems to have maintained to a certain degree an attitude of independence, if not of opposition, towards Augustus.
I, 22) and professed to detect in Livy's style certain provincialisms of his native Padua (Quintilian, i.
Dr Leche also institutes a comparison between the skeletons of the wild and the tame Bactrian camel with the remains of certain fossil Asiatic camels, namely, Camelus knoblochi from Sarepta, Russia, and C. alutensis from the Aluta valley, Rumania.
On the latter hypothesis it has been generally assumed that the wild camels are the descendants of droves of the domesticated breed which escaped when certain central Asian cities were overwhelmed by sand-storms. This theory, according to Professor Leche, is rendered improbable by Dr Sven Hedin's observations on the habits and mode of life of the wild camel.
Having come to an understanding with his father-in-law Podébrad, he was able to turn his arms against the emperor Frederick, and in April 1462 Frederick restored the holy crown for 60,000 ducats and was allowed to retain certain Hungarian counties with the title of king; in return for which concessions, extorted from Matthias by the necessity of coping with a simultaneous rebellion of the Magyar noble in league with Podebrad's son Victorinus, the emperor recognized Matthias as the actual sovereign of Hungary.
This is 490,251 higher than the actual population, 32,475,253, ascertained by the census of the 10th of February 1901; the difference is due to temporary absences from their residences of certain individuals on military service, &c., who probably were counted twice, and also to the fact that 469,020 individuals were returned as absent from Italy, while only 61,606 foreigners were in Italy at the date of the census.
A certain amount of linseed-oil is made in Lombardy, Sicily, Apulia and Calabria; colza in Piedmont, Lombardy, Venetia and Emilia; and castor-oil in Venetia and Sicily.
The principal reasons for the general decrease are the fall in prices through foreign competition and the closing of certain markets, the diseases of plants and the increased outlay required to combat them, and the growth of State and local taxation.
Large farms are f&und in certain of the more open districts; but in Italy generally, and especially in Sardinia, the land is very much subdivided.
In the famiglio da spesa the tiller receives a small wage and a proportion of certain products.
Chemicals sulphate of copper, employed chiefly as a preventive 01 certain maladies of the vine; carbonate of lead, hyper.
On the 17th of April 1898 a species of Employers Liability Act compelled employers of more than five workmen in certain industries to insure their employees against accidents.

The suffrage is extended to all citizens over twenty-one years of age who can read and write and have either attained a certain standard of elementary education or are qualified by paying a rent which varies from 6 in communes of 2500 inhabitants to 16 in communes of 15p,ooo inhabitants, or, if peasant farmers, I6s.
Senators and deputies receive no salary but have free passes on railways throughout Italy and on certain lines of steamers.
There is a council of state with advisory functions, which can also decide certain questions of administration, especially applications from local authorities and conflicts between ministries, and a court of accounts, which has the right of examining all details of state expenditure.
Besides many hundreds of princes, dukes, marquesses, counts, barons and viscounts, there are a large number of persons of patrician rank, persons with a right to the designation nobile or signor-i, and certain hereditary knights or cavalieri.
Certain types of dangerous individuals are relegated after serving a sentence in the ordinary convict prisons, and by administrative, not by judicial process, to special penal colonies known as domicilii coatti or forced residences.
The annual consumption per inhabitant of certain kinds of food and drink has considerably increased, e.g.
Certain banks make a special business of lending money to owners iif land or buildings (credito fo,zdiario).
The former qualifications for electorship in local government elections have been modified, and it is now sufficient to pay five lire annually in, direct taxes, five lire of certain communal taxes, or a certain rental (which varies according to the population of a commune), instead of being obliged to pay, as previously, at least five lire annually of direct taxes to the state.
Except, therefore, for a very small and apparently isolated area in the north of Latium and south of Etruria, all the tribes of Italy, though their idioms differed in certain particulars, are left undiscriminated.
While making these reservations, it is at thesame time right to observe that certain Italian communities were more advanced upon the path of independence than others.
Here again he cited the action of Charlemagne, his august predecessor, who had merely given certain domains to the bishops of Rome as fiefs, though Rome did not thereby cease to be part of his empire.
The powers, immediately after the revolt, presented a memorandum to Gregory recommending certain moderate reforms, but no attention was paid to it.
The new pope, who while bishop of Imole had evinced a certain interest in Liberalism, was a kindly man, of inferior intelligence, who thought that all difficulties could be settled with a little good-will, some reforms and a political amnesty.
But he did not move so fast in the path of reform as was expected, and agitation continued throughout the papal states.i In 1847 some administrative reforms were enacted, the laity were admitted to certain offices, railways were talked about, and political newspapers permitted.
It was certain that, his work in Sicily done, Garibaldi would turn his attention to the Neapolitan dominions on the mainland; and beyond these lay Umbria and the Marches andRome.
The irritation displayed by Bismarck at the Francophil attitude of Italy towards the end of the Franco-German War gave place to a certain show of goodwill when the great chancellor found himself in his turn involved in a struggle against the Vatican and when the policy of Thiers began to strain Franco-Italian relations.
Certain scandals had come to light in a small convent school at Greco near Milan.
In some cases there was foundation for the laborers claims, but unfortunately the movement got into the hands of professional agitators and common swindlers, and the leader, a certain Giampetruzzi, who at one time seemed to be a worthy colleague of Marcelin Albert, was afterwards tried and condemned for having cheated his own followers.
In the spring of 1908 there were agrarian strikes at Parma; the labor contracts had pressed hardly on the peasantry, who had cause for complaint; but while some improvement had been effected in the new contracts, certain unscrupulous demagogues, of whom Alceste De Ambris, representing the syndacalist wing of the Socialist party, was the chief, organized a widespread agitation.
The older, which extends to 150 B.C., set forth, in bald, unattractive language, without any pretensions to style, but with a certain amount of trustworthiness, the most important events of each successive year.
For instance, he asserts the number of the Sabine virgins to have been exactly 527; again, in a certain year when no Greek or Latin writers mention any important campaign, Antias speaks of a big battle with enormous casualties.
As unlicensed blood-letters, certain land-leeches are among the most unpleasant of parasites that can be encountered in a tropical jungle.
From it the other two fires, the anavaniya, or offering fire, and the dakshinagni, or southern fire, used for certain special purposes, are taken.
Given certain linear and angular measurements, the area must be so and so.
But nothing is more certain than that his thought is a strong solvent of the intuitionalist way of thinking; and he has had an immense influence in many directions.
Pure knowledge, for man, moves among a world of shadows; duty is certain.
There is perhaps a certain religious enthusiasm in the thought of being passively determined by Fate, the Universe, Zeus.
In other words; whenever philosophy g teaches a doctrine of the Absolute, and regards such doctrine as valid and certain, we have the essence of an ontological or a priori argument.
We may be helped in assigning him his proper place if we observe that, almost invariably, he accepts certain beliefs which he forbears to press.
Popular scepticism - perhaps even Charles Darwin's; Huxley himself was a student of Hume - understands by agnosticism that science is certain while philosophy and theology are baseless.
If this tendency is to take effect, a certain part of Kant's rational scepticism must be accepted.
It is hard to be certain that any systematic grouping will anticipate all the suggestions that may occur to a restlessly and recklessly inquiring age.
There is much faith in dreams, and in the utterances of certain "wise men," who practise an embryonic magic and witchcraft.
The total population of the settlement, consisting of convicts, their guards, the supervising, clerical and departmental staff, with the families of the latter, also a certain number of ex-convicts and trading settlers and their families, numbered 16,106.
It is not even possible in all cases to be certain that the polyp-group corresponds exactly to the medusagroup, especially in minor systematic categories, such as families.
The theory that the medusa is simply an organ, which has become detached and has acquired a certain degree of independence, like the well-known instance of the hectocotyle of the cuttle-fish.
Certain other forms of doubtful affinities have also been referred provisionally to this section.
In some cases, any polyp of the colony may bud medusae; in other cases, only certain polyps, the blastostyles, have this power.
It is certain, however, that no such classification can be considered final at present, but must undergo continual revision in the future.
Certain discrepancies must also be noted.
In a great many Leptomedusae the hydroid stage is as yet unknown, and it is by no means certain even that they possess one.
The coenosteum increases in size by new growth at the surface; and in the deeper, older portions of massive forms the tissues die off after a certain time, only the superficial region retaining its vitality down to a certain depth.
Since no graptolites are known living, or, indeed, since palaeozoic times, the interpretation of their structure and affinities must of necessity be extremely conjectural, and it is by no means certain that they are Hydrozoa at all.
It has been asserted that the tentaculocysts are entirely ectodermal and that either the family should be placed amongst the Leptomedusae, or should form, together with certain Leptomedusae, an entirely distinct order.
The various grades of life on our planet are the natural consequences of certain physical processes involved in the gradual transformations of the earth.
Yet on the whole Aristotle leans to a teleological theory of evolution, which he interprets dualistually by means of certain metaphysical distinctions.
In certain writers, however, there appears a more elaborate transformation of the doctrine of creation into a system of emanation.
Pollock has taken pains to show how nearly Spinoza approaches certain ideas contained in the modern doctrine of evolution, as for example that of sell-preservation as the determining force in things.
In Locke we find, with a retention of certain antievolutionist ideas, a marked tendency to this mode of viewing the world.
Locke half playfully touches on certain monsters, with respect to which it is difficult to determine whether they ought to be called men.
Helvetius, in his work on man, referred all differences between our species and the lower animals to certain peculiarities of organization, and so prepared the way for a conception of human development out of lower forms as a process of physical evolution.
He left open the question whether the capability of sensation belongs to all matter, or is confined to the combinations of certain materials.
Notwithstanding the origin of organs, it still for a certain time, by reason of its want of an internal bony skeleton, remains worm and mollusk, and only later enters into the series of the Vertebrata, although traces of the vertebral column even in the earliest periods testify its claim to a place in that series."
But the causes and conditions of variation have yet to be thoroughly explored; and the importance of natural selection will not be impaired, even if further inquiries should prove that variability is definite, and is determined in certain directions rather than in others, by conditions inherent in that which varies.
It is necessary to notice, however, that although the general course of the stream of life is certain, there is not the same certainty as to the actual individual pedigrees of the existing forms. In the attempts to place existing creatures in approximately phylogenetic order, a striking change, due to a more logical consideration of the process of evolution, has become established and is already resolving many of the earlier difficulties and banishing from the more recent tables the numerous hypothetical intermediate forms so familiar in the older phylogenetic trees.
The accusations are frequently unfounded; but the trials are already conducted in a certain regular forensic form.
Certain enactments of later Saxon times in England have been sometimes spoken of as though they united together the temporal and spiritual jurisdictions into one mixed tribunal deriving its authority from the State.
The 6th council of Toledo (in 693) has been cited as if it visited certain very great sinners with scourging as an ecclesiastical punishment.
The occupants of certain sees by a kind of prescription became legates without special appointment, legati nati, as in the case of Canterbury.
Whatever may have been the law, it is certain that, notwithstanding the statutes of Edw.
In 1438 the council of Basel took away all papal original jurisdiction (save in certain reserved cases - of which infra), evocation of causes to Rome, appeals to Rome omisso medio, and appeals to Rome altogether in many causes.
Even as to the discipline of the Roman clergy it is only in certain limited cases that one can speak of ecclesiastical jurisdiction.
As a result, however, partly of the usual want of work on the grasslands in certain seasons, there has been a considerable emigration to America.
A certain amount of progress has been made in the historical criticism of these books.
It has been assumed on the strength of a passage in Capitolinus that Aurelius married Faustina in 146, but the passage is not clear, and other evidence points strongly to 140; at all events it seems certain that a daughter was born to him in 140.
When, therefore, we remember that Aurelius knew little of the Christians, that the only mention of them in the Meditations is a contemptuous reference to certain fanatics of their number whom even Clement of Alexandria compares for their thirst for martyrdom to the Indian gymnosophists, and finally that the least worthy of them were doubtless the most prominent, we cannot doubt that Aurelius was acting unquestionably in the best interests of a perfectly intelligible ideal.
It is still believed to possess certain medicinal virtue.
Amber and certain similar substances are found to a limited extent at several localities in the United States, as in the greensand of New Jersey, but they have little or no economic value.
All yield a soft, easily-worked timber, which, though very perishable when exposed to weather, possesses sufficient durability when kept dry to give the trees a certain economic value.
The rules of the Orphic life prescribed abstinence from beans, flesh, certain kinds of fish, &c., the wearing of a special kind of clothes, and numerous other practices and abstinences.
This is particularly marked in certain lichens of shrubby habit.
In the liverworts we find fixation of the thallus by water-absorbing rhizoids; in certain forms with a localized region of water-absorption the development of a primitive hydrom or water-conducting system; and in others with rather a massive type of thallus the differentiation of a special assimilative and transpiring system.
This is found especially in plants which during certain hours of the day are unable to cover the water lost through transpiration by the supply coming from the roots.
They are widely distributed, but are particularly abundant in certain tropical climates where active root absorption goes on while the air is nearly saturated with water vapour.
In certain families of Angiosperms a peculiar tissue, called laticiferous tissue is met with.
As a secondary function we may recognize, in certain cases, the power of closing wounds, which results from the rapid coagulation of exuded latex in contact with the air.
Later, the axis branches by the formation of new growing-points, and in this way the complex system of axes forming the body of the ordinary vascular plant is built up. In the flowering plants the embryo, after developing up to a certain point, stopf growing and rests, enclosed within the seed.
The tissue-elements just described are found only in the more complicated secondary vascular tissues of certain Dicotyledons.
An ordinary cambium is scarcely ever found in the Monocotyledons, but in certain woody forms a secondary meristem is formed outside the primary bundles, and gives rise externally to a little secondary cortex, and internally to a secondary parenchyma in which are developed numerous zones of additional bundles, usually of concentric structure, with phloem surrounded by xylem.
In other cases, a similar formation of spongy but dead periderm tissue may occur for the same purpose in special patches, called pneumatodes, on the roots of certain trees living in marshy places, which rise above the soil in order to obtain air.
Certain cells of the exterior are set apart for absorption of water from the soil, this being the source from which supplies are derived.
This view requires the existence of certain anatomical arrangements to secure the isolation of the separate columns, and cannot be said to be fully established.
Its nutritive pabulum is supplied to it in the shape of certain complex organic substances which have been stored in some part or other of the seed, sometimes even in its own tissues, by the parent plant from which it springs.
They are mainly carbohydrates such as starch and sugar, proteids in the form of globulins or albumoses, and in many cases fats and oils, while certain other bodies of similar nutritive value are less widely distributed.
These bodies, known technically as chioroplaIts, are found embedded in the protoplasm of the cells of the mesophyll of foliage leaves, of certain of the cells of some of the leaves of the flower, and of the cortex of the young twigs and petioles.
It is not certain either whether the action of the chlorophyll apparatus is confined to the manufacture of carbohydrates or whether it is concerned, and if so how far, with the construction of proteids also.
In addition, certain inorganic salts, particularly certain compounds of potassium, are apparently necessary, but they seem to take no part in the chemical changes which take place.
The formation of formaldehyde has till recently not been satisfactorily proved, though it has been obtained from certain leaves by distillation.
Certain Algae have been found capable of forming nutritive carbohydrates in darkness, when supplied with a compound of this body with sodium-hydrogen-sulphite.
But it is certain that it can only be present in a cell in very small amount at any moment, for an extremely dilute solution acts as a poison to protoplasm.
Nor is the nature of the first formed sugar certain; the general opinion has been that it is a simple hexose such as glucose or fructose, C6Hi2O,.
The independence of the two is suggested by the fact that fungi can live, thrive and grow in nutritive media which contain carbohydrates together with certain salts of ammonia, but which are free from proteids.
It is certain that their protoplasm cannot be nourished by inorganic compounds of nitrogen, any more than that of animals.
The probability is that this mechanism is to be found in green plants in the leavesat any rate there is a certain body of evidence pointing in this direction.
It may be, however, that there is no special mechanism, but that this power is a particular differentiation of a physiological kind, existing in all vegetable protoplasm, or in that of certain cells.
There is a certain amount of evidence that at any rate in some cases light is necessary, and that the violet rays of the spectrum are chiefly concerned.
The power of green plants, not even specialized in any of these directions, to absorb certain carbohydrates, particularly sugars, from the soil was demonstrated by Acton in 1889.
The habit of forming mycorhizas is found more frequently in warm climates than cold; indeed, the percentage of the flora exhibiting this peculiarity seems to increase with a certain regularity from the Arctic Circle to the equator.
Fixation of Nitrogen.Another, and perhaps an even more important, instance of symbiotic association has come to the front during the same period, it is an alliance between the plants of the Natural Order Leguminosae and certain bacterium-like forms which find a home within the tissues of their roots.
After making its way into the interior, the intruder sets up a considerable hyper trophy of the tissue, causing the formation of a tubercle, which soon shows a certain differentiation, branches of the vascular bundles of the root being supplied to it.
Certain evidence which supports this view will be referred to later.
The enzymes which act upon glucosides are many; the best known are emul sin and myrosin, which split up respectively amygdalin, the special glucoside of certain plants of the Rosaceae; and sinfgrin, which has a wide distribution among those of the Cruciferae.
It is not quite certain whether a true pepsin exists in plants, but many trypsins have been discovered, and one form of erepsin, at least, is very widespread.
It is marked by the constant and continuous absorption of a certain quantity of oxygen and bythe exhalation of a certain volume of carbon dioxide and water vapour.
The protoplasm is in a condition of instability and is continually breaking down to a certain extent, giving rise to various substances of different degrees of complexity, some of which are again built up by it into its own substances, and others, more simple in composition, are given off.
The outcome of the whole round of changes, however, is the fixation of a certain part of the radiant energy absorbed by the chlorophyll.
Certain plants possess another source of energy which is common to them and the animal world.
The decomposition of the complex molecule of the sugar liberates a certain amount of energy, as can be seen from the study of the fermentation set tig by yeast, which is a process of this kind, in that it is intensified by the absence of oxygen.
This is not perhaps so evident in the case of axial organs as it is in that of leaves and their modifications, but even in them it can be detected to a certain extent.
There is set up at once a certain hydrostatic pressure, due to the turgidity which ensues upon such absorption, and the extensible cell wall stretches, at first in all directions.
Growth is small, and consists mainly in an increase of the quantity of protoplasm, for the cells divide again as soon as they have reached a certain size.
Even the root tip, which shows a certain differentiation into root cap and root apex, cannot be said to be a definite sense organ in the same way as the sense organs of an animal.
Many experiments point to certain small grains of starch which are capable of displacement as the position of the cell is altered.
More slowly, but yet in the same way, we may note the change in turgidity of certain cells of the Droscra tentacles, as they close over the imprisoned insect.
Every plant is constrained to carry Out its functions of germination, growth, nutrition, reproduction, &c., between certain limits of temperature, and somewhere between the extremes of these limits each function finds ao optimum temperature at which the working of the living machinery is at its best, and, other things being equal, any great departure from this may induce pathological conditions; and many disasters are due to the failure to provide such suitable temperaturese.g.
Schinzia, which forms galllike swellings on the roots of rushes; Gymnosporangium, causing excrescences on juniper stems; numerous leaf Fungi such as Puccinia, Aecidium, Sep/one, &c., causing yellow, brown or black spots on leaves; or Ustilago in the anthers of certain flowers.
In such cases the immediate damage done may be slight; but the effects of prolonged action and the summation of numerous attacks at numerous points are often enormotis, certain of these leafdiseases costing millions sterling annually to some planting and agricultural communities.
The various degrees of parasitism are to a certain extent explained by the foregoing.
Care and intelligence are especially needful with certain insecticides such as poisonous gases, or the operators may suffer.
White or grey spots may be due to Peronospora, Erysiphe, Cystopus, Entyloma and other Fungi, the mycelium of which will be detected in the discoloured area; or they may be scale insects, or the results of punctures by Red-spider, &c. Yellow spots, and especially bright orange spots, commonly indicate Rust Fungi or other Uredineae; but Phyllosticta, Exoascus, Clasterosporium, Synchytrium, &c., also induce similar symptoms. Certain Aphides, Red-spider, Phylloxera and other insects also betray their presence by such spots.
But the occluding callus is a mass of delicate succulent cells, and offers a dainty morsel to certain insects e.g.
Aphidesand may be easily penetrated by certain Fungi such as Peziza, Nectria; and when thus attacked, the repeated conflicts between the cambium and callus, on the one hand, trying to heal over the wound, and the insect or Fungus, on the other, destroying the new tissues as they are formed, results in irregular growths; the still uninjured cambium area goes on thickening the branch, the dead parts, of course, remain unthickened, and the portion in which the Fungus is at work may for the time being grow more rapidly.
At certain seasons the wound bleeds, and the organismssome of which, by the bye, are remarkable and interesting formsmultiply in the nutritious sap and ferment it.
Outflows of resinResinosisalro come under this general heading; but although some resin-fluxes are traced to the destructive action of Agaricus melleus in Conifers, others, as well as certain forms of Gummosis, are still in need of explanation.
Again, the well-known action of earthworms may be said to be a biological work; but the resulting aeration of the soil causes edaphic differences; and earthworms are absent from certain soils, such as peat.
Submerged leaves are usually filamentous or narrowly ribbonshaped, thus exposing a large amount of surface to the water, some of the dissolved gases of which they must absorb, and into which they must also excrete certain gases.
The interesting occurrence of certain halophytes and hemi-halophytes on sea-shores and also on mountains is probably to be explained by the past distribution of the species in question.
In the west of Ireland and in the Faroes, where certain inland and lowland localities are still uncultivated, Plantage maritfma and other halophytes occur in quantity and side by side with some Alpine species, such as Dryas octopetala.
Lesagef has shown that the height of certain plants is decreased by cultivation in a saline soil, and that the leaves of iLesage, Recherches exphrimentales sur les modifications de, feuilles chez les plantes maritimes, in Rev. gen.
The chloroplasts increase in number by division., which takes place in higher plants when they have attained a certain size, independent of the division.
In order to effect this the individual chromosomes must become associated in some way, for there is no diminution in the actual amount of nuclear substance, and this leads to certain modifications in the division which are not seen in the vegetative nuclei.
Cell Division.With the exception of a few plants among the Thallophytes, which consist of a single multinucleate cell, Caulerpa, Vaucheria, &c., the division of the nucleus is followed by the division of the cell either at once, in uninucleate cells, or after a certain number of nuclear divisions, in multinucleate cells.
Whether this is entirely confined to the nucleus is, however, not certain.
Organs which respond to the mechanical stimulus of contact are found to possess special contrivances in certain of their cells(I) sensitive spots, consisting of places here and there on the epidermal cells where the wall is thin and in close contact with protoplasmic projections.
These occur on the tips of tendrils and on the tentacles of Drosera; (2) sensitive papillae found on the irritable filaments of certain stamens; and (3) sensitive hairs or bristles on the leaves of Dionaea muscipula and Mimosa pudicaall of which are so constructed that any pressure exerted on them at once reacts on the protoplasm.
Sieve Tubes.The sieve tubes consist of partially fused rows of cells, the transverse cr lateral walls being perforated by minute openings, through which the contents of the cells are connected with each other, and which after a certain time become closed by,the formation of callus on the sieve plates.
Companion cells are not found in the Pteridophyta and Gymnosperms. In the latter their place is taken by certain cells of the medullary rays and bast parenchyma.
Joachim Jung, in his Isagoge phytoscopica (1678), recognized that the plant-body consists of certain definite members, root, stem and leaf, and defined them by their different form and by their mutual relations.
In the former case the nature of the organism is such that it yields readily, when subjected to certain conditions, and all or nearly all the individuals become modified in the same way.
It is also probable that the various forms of the angiospermous flower, with its many specialized mechanisms for pollination, may be the result of insect-visits, the flowers becoming adapted to certain kinds of insects, and the insects having undergone corresponding modification.
It is true that the earths physical geography presents certain broad features to which plants are adapted.
It is certain that they originally existed under warmer conditions of climate than now obtain, and that progressive refrigeration.
By sahel any coast belt may be indicated, but the name has become the definite designation of certain districts, e.g.
Certain ancient stringed instruments were played with a plectrum or plucker made of the quill of a bird's feather, and the word has thus been used of a plectrum made of other material and differing in shape, and also of an analogous object for striking the strings in the harpsichord, spinet or virginal.
Beryllium to a certain extent stands alone in many of its chemical' properties, resembling to some extent the metal aluminium.
In consequence of the complaints of certain Galatian princes, DeIotarus was deprived of part of his dominions, but allowed to retain the title of king.
In order to obtain the phenol from this distillate, it is treated with caustic soda, which dissolves the phenol and its homologues tegether with a certain quantity of naphthalene and other hydrocarbons.
Hantzsch (Ber., 1901, 34, p. 3337) has shown that in the action of alcohols on diazonium salts an increase in the molecular weight of the alcohol and an accumulation of negative groups in the aromatic nucleus lead to a diminution in the yield of the ether produced and to the production of a secondary reaction, resulting in the formation of a certain amount of an aromatic hydrocarbon.
The discovery of their true nature was made by Dr William Buckland, who observed that certain convoluted bodies occurring in the Lias of Gloucestershire had the form which would have been produced by their passage in the soft state through the intestines of reptiles or fishes.
