In North America the Carolina parakeet, Conurus carolinensis, at the beginning of the i 9th century used to range in summer as high as the shores of lakes Erie and Ontario - a latitude equal to the south of France; and even much later it reached, according to trustworthy information, the junction of the Ohio and the Mississippi, though now its limits have been so much curtailed that its occurrence in any but the Gulf States is doubtful.
2 The statements that have been made, and even repeated by writers of authority, as to the occurrence of "a green parrot" in Syria (Chesney, Exped.
Pollination on the surface, a more frequent occurrence than (a).
In the latter respect, and in the fact that they frequently develop by a metamorphosis, they approach the Mollusca, but they differ from that group notably in the occurrence of metameric segmentation affecting many of the systems of organs.
Capellus drew conclusions from such important facts as the occurrence of variations in the two Hebrew texts of passages found twice in the Old Testament itself, and the variations brought to light by a comparison of the Jewish and Samaritan texts of the Pentateuch, the Hebrew text and the Septuagint, the Hebrew text and New Testament quotations from the Old Testament.
25) questions were raised by the occurrence of the formula " until this day " in Jos.
Hobbes, drew attention in particular to the confused mixture of law and narrative in the Pentateuch, the occurrence of duplicate narratives and chronological incongruities.
Over a large part of the central Pacific, far removed from any possible land-influences or deposits of ooze, the red-clay region is characterized by the occurrence of manganese, which gives the clay a chocolate colour, and manganese nodules are found in vast numbers, along with sharks' teeth and the ear-bones and other bones of whales.
Diatom ooze has been found in detached areas between the Philippine and Mariana islands, and near the Aleutian and Galapagos groups, forming an exception to the general rule of its occurrence only in high latitudes.
In the central and western Pacific the northern and southern limits of the occurrence of reef-forming corals are approximately 30 N.
The occurrence of this process can be predicted exactly for one day, before sunrise, in October and November, and as both the worm and the fish which prey on it are appreciated by the natives as food the occasions of its appearance are of great importance to them.
Floods are of common occurrence, and descend very suddenly.
Throughout the volcanic area earthquakes and landslides are of frequent occurrence.
On the other hand the cult of a specific storm-god in ancient Babylonia is vouched for by the occurrence of the sign Im - the "Sumerian" or ideographic writing for Adad-Ramman - as an element in proper names of the old Babylonian period.
The logarithm is also a function of frequent occurrence in analysis, being regarded as a known and recognized function like sin x or tan x; but in mathematical investigations the base generally employed is not 10, but a certain quantity usually denoted by the letter e, of value 2.71828 18284 ...
While establishing the historic divisions of the Silurian in Bohemia, Barrande also propounded his famous theory of " colonies," by which he attempted to explain the aberrant occurrence of strata containing animals of a more advanced stage among strata containing earlier and more primitive faunas; his assumption was that the second fauna had migrated from an unknown neighbouring region.
Slight shocks, or temblores, are of almost daily occurrence.
The sexes are always separate, the males being of very rare occurrence in most cases.
The males of rotifers are of relatively rare occurrence, except in the genus A splanchna, where they were first recognized as such by Brightwell in 1841; though those of Hydatina had long since been seen and described as a distinct genus.
Despite their rare occurrence, the males of over one hundred and twenty species have now been recognized, and we may well believe that all species will be found to present males.
Large masses with a coarse or fine granular structure are of common occurrence; the fractured surfaces of such masses present a spangled appearance owing to the numerous bright cleavages.
That these animals were widely distributed in former times is proved by their occurrence at the present day in palaeozoic fossiliferous strata both of the northern hemisphere and of Australia; and despite the fact that their remains have not been found in rocks of the Mesozoic or Kainozoic epochs, it was conceived to be possible that living specimens might be dredged from the sea-floor during the exploration of the ocean depths undertaken by the "Challenger" expedition.
In December 1895 the occurrence of the Jameson Raid, which started from these territories, prevented the completion of negotiations, and the administration of the protectorate remained in the hands of the imperial government.
In the two or three years following several other observers recorded the occurrence of similar haematozoa in various fishes.
Among batrachians the parasites have been found, up till now, only in frogs; and among reptiles their occurrence has only been observed in one or two solitary instances (T.
In considering the occurrence of Trypanosomes in mammals, careful distinction must be drawn between natural or true hosts, which are tolerant of the parasites, and casual ones, which are unaccustomed and unadapted to them.
In certain forms the occurrence of prominent myonemes or muscle-fibrillae has been described, and, moreover, a nuclear origin assigned to them also.

Minchin, " On the occurrence of encystation in Trypanosoma grayi," &c., Proc. Roy.
There is no evidence of the existence of a cult of Caelus, the occurrence of the name in dedicatory inscriptions being due to Oriental influences, the worship of the sky being closely connected with that of Mithras.
The absence of range-like continuity is here emphasized by the occurrence of several low passes or notches leading directly through the group; the best-known being Crawfords Notch (1900 ft.).
The drainage of New England is unlike that of the middle and south-western Appalachians in the occurrence of numerous lakes and falls.
The bofindary between the mountains and the piedmont belt is called the Blue Ridge all along its length; and although the nan:e is fairly appropriate in northern Virginia, it is not deserved in the Carolinas, where the ridge is only an escarpment descending abruptly 1000 or 1500 ft~ from the valleys of the mountain belt to the rolling uplands of the piedmont belt; and as such it is a form of unusual occurrence.
The small triangular section of the coastal plain in New Jersey north of Delaware Bay deserves separate treatment because of the development there of a pectiliar topographic feature, which throws light on the occurrence of the islands off the New England coast, described in the next paragraph.
The feature referred to results from the occurrence here of a weak basal formation of clay overlaid by more resistant sandy strata; the clay belt has been stripped for a score or more of miles from its original inland overlap, and worn down in a longitudinal inner lowland, while the sandy belt retains a significant altitude of 200 or 300 ft.
The occurrence of the lake basins in the lowland belts on either side of the Niagara cuesta is an abnormal feature, not to be explained by ordinary erosion, which can produce only valleys.
The western half of the basin occupies a trough of synclinal structure; but the making of this syndine is so ancient that it cannot be directly connected with the occurrence of the lake to-day.
The growth of the meanders tends to give the river continually increasing length; but this tendency is counteracted by the sudden occurrence of cut-offs from time to time, so that a fairly constant length is maintained.
The floods of the Mississippi usually occur in spring or aummer; Owing to the great size of the drainage basin, it seldom happens that the three upper tributaries are in flood at the same time; the coincident occurrence of floods in only two tributaries is of serious import in the lower river, which rises 30, 40, or occasionally 50 ft.
Another consequence of revived erosion is seen in the occurrence of great landslides, where the removal of weak (Permian) clays has sapped the face of the Vermilion Cliffs (Triassic sandstone), so that huge slices of the cliff face have slid down and forward a mile or two, all shattered into a confused tumult of forms for a score or more of miles along the cliff base.
Thus the heaviest measured rainfall east of the Mississippi is on the southern Appalachians; while in the west, where observations are as yet few at high level stations, the occurrence of forests and pastures on the higher slopes of mountains which rise from desert plains clearly testifies to the same rule.
Serious deadlocks are of comparatively rare occurrence.
But two circumstances tended to prevent the occurrence of such irregularities.

It is important, because such a concrescence is by no means universal, and does not occur, for example, in Mytilus or in Arca; further, because when its occurrence is once appreciated, the reduction of the gill-plates of Anodonta to the plume-type of the simplest ctenidium presents no difficulty; and, lastly, it has importance in reference to its physiological significance.
The May-flies are remarkably primitive in certain of their characters, notably the elongate cerci, the paired, entirely mesodermal genital ducts, and the occurrence of an ecdysis after the acquisition of functional wings.
249) that the parallel occurrence of the names Sarapis and Osorapis (Userhapi) points to an independent origin for the former.
In the west the Herauch, a thick fog arising from the burning of the moors, is a plague of frequent occurrence.
The Trochosphere-hypothesis (2), (3) is based chiefly on the occurrence in certain Polyclad Turbellaria, of a larval form (Miiller's larva) which is comparable to a certain stage (pro-trochula) in the development of the Trochosphere-larva.
The grounds for this view are the radial symmetry of several Polyclads and the supposed origin of gonads and excretory flame-cells from the walls of gut, the occurrence of nematocysts in Anonymus, one of the most radially constructed Polyclads, and lastly the presence of two peculiar animals Ctenoplana and Coeloplana, which suggests a transition from Ctenophora to Polyclads.
From this occurrence may be dated the jealousy which the cardinal began to exhibit towards More.

Deformed examples are not of rare occurrence.
Xajscw (meadow), in allusion to its occurrence as "bog-ore" in meadows and marshes.
It was observed by the animal magnetists at the beginning of the 19th century in France and Germany, that certain of their subjects, when in the "magnetic" trance, could foretell accurately the course of their diseases, the date of the occurrence of a crisis and the length of time needed to effect a cure.
This, coupled with the occurrence of earlier types in North America, indicates that the group is a northern one.
gallinula, the smallest and most beautifully coloured of the group. Without being as numerous as the common or full Snipe, it is of frequent occurrence in Great Britain from September to April (and occasionally both earlier and later); but it breeds only, so far as is known, in N.
A few possible cases of aggressive mimicry are enumerated in the following summary of some of the recorded cases of mimicry in different classes of the animal kingdom; but the phenomenon is of comparatively rare occurrence, and the supposed instances may be susceptible of other interpretations, excluding them altogether from mimicry, or bringing them under the Batesian or Miillerian interpretation of the phenomenon.
Considering, however, the numbers of venomous and innocuous snakes that occur in most tropical countries, it might be supposed that mimicry in this order of reptiles would be of commoner occurrence than appears to be the case.
Special attention may be drawn to two phenomena connected with it, both of not uncommon occurrence in mimetic Lepidoptera.
This is a not uncommon occurrence, and in the case of Batesian mimicry the explanation is probably this.

As for the explanation of the community between the alpine and arctic floras, all authorities are agreed that the key to the problem is furnished by the occurrence of the glacial period.
The occurrence of hybrids in nature explains the difficulty experienced by botanists in deciding on what is a species, and the widely different limitations of the term adopted by different observers in the case of willows, roses, brambles, &c. The artificial process is practically the same in hybridization as in cross-fertilization, but usually requires more care.
It should be observed, however, that the repeated intercalation of marine deposits within the continental series and the frequent occurrence of thin coaly layers in the marine series makes any hard and fast distinction of this kind impossible.
The occurrence of red deposits in western Australia, Scotland, the Ural mountains, in Michigan, Montana and Nova Scotia, &c., associated in some instances with the formation of gypsum and salt, clearly points to the existence of areas of excessive evaporation, such as are found in land-locked waters in regions where something like desert conditions prevail.
Invisible to the microscope, but rendered visible by reagents, are glycogen, Mucor, Ascomycetes, yeast, &c. In addition to these cell-contents we have good indirect evidence of the existence of large series of other bodies, such as proteids, carbohydrates, organic acids, alkaloids, enzymes, &c. These must not be confounded with the numerous substances obtained by chemical analysis of masses of the fungus, as there is often no proof of the manner of occurrence of such bodies, though we may conclude with a good show of probability that some of them also exist preformed in the living cell.
In connexion with this condition of reduction a fusion of nuclei has been observed in Humaria rutilans and is probably of frequent occurrence.

One fact or perception is discovered by experience to be uniformly or generally accompanied by another, and its occurrence therefore naturally excites the idea of that other.
This explains a good deal of the possible instability; and, from a practical point of view, it coincides with the fact that such a large amount of energy can be stored in our most intense explosives such as dynamite, the explanation being that hydrogen is attached to carbon distant from oxygen in the same molecule, and that only the characteristic resistance of the carbon linkage prevents the hydrogen from burning, which is the main occurrence in the explosion of dynamite.
During the Crusades, and in the middle ages, the term Belgicae principes is of frequent occurrence, and when in 1790 the Walloons rose against Austria during what was called the Brabant revolution, their leaders proposed to give the country the name of Belgique.

The Inverell occurrence may prove to be another example of diamond crystallized from a basic rock.
Kunz, " Diamonds, a study of their occurrence in the United States, with descriptions and comparisons of those from all known localities" (U.S. Geol.
" The occurrence of stones and boulders far removed from their parent source early attracted the attention of geologists, but for a long period the phenomena, now known as of glacial origin, were unexplained, and the drifts were looked upon as little more than ` extraneous rubbish,' the product of geological agents, quite distinct from those which helped to form the more ` solid ' rocks that underlie them."
Abortion resembles ordinary labour in its general phenomena, excepting that in the former hemorrhage often to a large extent forms one of the leading symptoms. The treatment embraces the means to be used by rest, astringents and sedatives, to prevent the occurrence when it merely threatens; or when, on the contrary, it is inevitable, to accomplish as speedily as possible the complete removal of the entire contents of the uterus.
From the mode of destruction of the city these upper floors were in most cases crushed in and destroyed, and hence it was long believed that the houses for the most part had but one storey; but recent researches have in many cases brought to light incontestable evidence of the existence of an upper floor, and the frequent occurrence of a small staircase is in itself sufficient proof of the fact.
Crystals of blende are of very common occurrence, but owing to twinning and distortion and curvature of the faces, they are often rather complex and difficult to decipher.

was the hour of most frequent occurrence for arcs and bands, whereas patches had their maximum frequency at I I P.M.
That a subsequent land connexion took place, however, by the elevation of the sea-bed there is abundant evidence to show; and the occurrence of the remains of African Quaternary mammals, such as Elephas meridionalis, E.

Anacolutha are of frequent occurrence, and cannot be explained as conscious literary devices.
A white fog, dense and cold, sometimes rises from the Nile in the morning, but it is of short duration and rare occurrence.
It would be no surprise to find examples of the practice in other ranks also at an early period, as it certainly was prevalent in the Hellenistic age, but as yet it is very difficult to prove its occurrence.
Before the year was out the new sultan had been rendered unpopular by the occurrence of a famine, and Malik al-Na~ir was easily able to induce the Syrian amirs to return to his allegiance, in consequence of which Bibars in his turn abdicated, and Malik al-Ng~ir re-entered Cairo as sovereign on the 5th of March 1310.
It seems, especially in the case of the nexus between certain neurons, that the influence, loss of which endangers nutrition, is associated with the occurrence of something more than merely the nervous impulses awakened from time to time in the leading nerve cell.
Tradeunionism flourishes in Denmark, and strikes are of frequent occurrence.
occurrence of a food-reserve; many so-called exalbuminous seeds show to microscopic examination a distinct endosperm which may have other than a nutritive function.

A characteristic feature of the more massive species is the occurrence of air-vesicles in their tissues.
The asexual cells are termed tetraspores on account of the usual occurrence of four in each sporangium.
But it is clear that it becomes on this view increasingly difficult to explain the occasional occurrence of tetraspores on male, female and monoecious plants or the role of the carpospores in the life-cycle of Florideae.
With reference to their chemical physiology, the gelatinization of the cell-wall, which is so marked a feature, is doubtless attributable to the occurrence along with cellulose of pectic compounds.
The occurrence of characteristic algae at different levels constituting the zones to which reference has already been made, is probably in part an expression of the fact that different species vary in the capacity to resist desiccation from exposure.
Some Siphonales (Codium) give rise to proteid crystalloids, and they are of constant occurrence among Florideae.
The occurrence of a plentiful mucilage in many freshwater forms is, however, doubtless a provision against desiccation on exposure.
One of the most interesting features of the Scottish development of the Permian system is the occurrence of intercalated bands of contemporaneously erupted volcanic rocks in the Carron, Nithsdale and Ayrshire.
The Lower Oolite is distinguished by the occurrence in it of some coal-seams, one of which, 31 ft.
Co-operation of the two factors appears to supply a causal theory of the occurrence of evolution; the suggestion of their co-operation and the comparison of the possible results with the actual achievements of breeders in producing varieties were the features of Charles Darwin's theoretical work which made it a new beginning in the science of biology, and which reduced to insignificance all earlier work on the theory of evolution.
So long as we confine our attention to one or two individuals, we fail to detect any order in the occurrence of variations; but when we examine large numbers we find that it is possible to arrange them in an orderly series, which can be easily and simply described.
The analogy possibly may be extended to such cases as the occurrence of flora or fauna with alpine characters on the summits of mountains separated by broad zones of tropical climate.
It is plain that whilst the existence of variation can be demon strated and the occurrence of evolution established by induction and deduction, the part played by selection must remain largely theoretical.
Divorce was an easy matter, and of frequent occurrence; but, as a rule, a divorced wife would not marry again without the consent of her former husband.

The prevalence of elephantiasis and the occurrence of leprosy, for instance, in Hawaii, would seem to point at least in some places to a racial taint, due perhaps to the unbridled licentiousness of past generations.
It is possible that there may be warm springs on the bed of Lake Victoria, as such springs are of frequent occurrence in the Pamirs; but there is no indication of them in the Chakmaktin basin, and the latter lake must be regarded rather as an incident in the course of the Aksu - a widening of the river channel in the midst of this highlevel, glacier-formed valley - than as the fountain-head of the infant stream.
As soon as the news of his banishment spread through the city, the astonishment of the people was quickly exchanged for a spirit of irresistible fury, which was increased by the occurrence of an earthquake.
The occurrence of anchovies in the English Channel has been carefully studied at the laboratory of the Marine Biological Association at Plymouth.

Among themselves the Afghans are quarrelsome, intriguing and distrustful; estrangements and affrays are of constant occurrence; the traveller conceals and misrepresents the time and direction of his journey.
The history of the Afghan countries under the Mongols is obscure; but that regime must have left its mark upon the country, if we judge from the occurrence of frequent Mongol names of places, and even of Mongol expressions adopted into familiar language.
It is not unlikely that such changes have in past time occurred; and if so an explanation is afforded of the occurrence of allied forms of freshwater dolphins (Platanista) and of many other animals in the two rivers and in the Brahmaputra.

Individuals reproduce unexpectedly the traits of earlier ancestors, and ethnologists and criminologists frequently explain by "atavism" the occurrence of degenerate species of man; but the whole subject is complicated by other possible explanations of such phenomena, included in the scientific study of normal "variation."
It is true that these fossils are not invariably present in every occurrence of Cambrian strata, but this fact notwithstanding, the threefold division holds with sufficient constancy.
Three regions deserve special attention: (I) Great Britain, the area in which the Cambrian was first differentiated from the old "Transition Series"; (2) North America, on account of the wide-spread occurrence of the rocks and the abundance and perfection of the fossils; and (3) Bohemia, made classic by the great labours of J.

These examples will show that mere statistics of the occurrence of words prove little, and that we must begin by looking to the subject and character of each poem.
The generally recognized principal Avatars do not, however, by any means constitute the only occasions of a direct intercession of the deity in worldly affairs, but - in the same way as to this day the eclipses of the sun and moon are ascribed by the ordinary Hindu to these luminaries being temporarily swallowed by the dragon Rahu (or Graha, " the seizer") - so any uncommon occurrence would be apt to be set down as a special manifestation of divine power; and any man credited with exceptional merit or achievement, or even remarkable for some strange incident connected with his life or death, might ultimately come to be looked upon as a veritable incarnation of the deity, capable of influencing the destinies of man, and might become an object of local adoration or superstitious awe and propitiatory rites to multitudes of people.
He is the first to introduce the name of Attila, and dates the occurrence 453.
As a rule this disease is due to a lack of tannin (hence its more frequent occurrence in white wines).
Confirmation of this is afforded by the occurrence in the mountains of Java of a pariah-like dog which has reverted to an almost completely wild condition; and likewise by the fact that the old voyagers met with dogs more or less similar to the dingo in New Guinea, New Zealand and the Solomon and certain other of the smaller Pacific islands.

Its most interesting feature is the occurrence near its summit, north of Cape Mondego, of sands and gravels containing plant remains.
Here, too, the occurrence of repetitions and divergencies, the variations of standpoint and practice, and, at times, the linguistic peculiarities point no less clearly to diversity of origin.
This race is often termed `` Celtic " or " Alpine " from the fact of its occurrence all along the great mountain chain from south-west France, in Savoy, in Switzerland, the Po valley and Tirol, as well as in Auvergne, Brittany, Normandy, Burgundy, the Ardennes and the Vosges.
The occurrence of the Anglo-Saxon compounds ymbren-tid, ymbren-wucan, ymbren fcestan, ymbren-dagas for Ember tide, weeks, fasts, days, favours the former derivation, which is also confirmed by the use of the word imbren in the acts of the council of iEnham, A.D.
The occurrence of a starch-like substance which stains deep blue with iodine has been clearly shown in some forms even where the bacterium is growing on a medium containing no starch, as shown by Ward and others.
We have thus an explanation of the occurrence of marsh gas and sulphuretted hydrogen in bogs, and it is highly probable that the existence of these gases in the intestines of herbivorous animals is due to similar putrefactive changes in the undigested cellulose remains.
The more recent researches of Molisch have shown that the luminosity of ordinary butcher's meat under appropriate conditions is quite a common occurrence.
Certain toxins resemble enzymes as regards their conditions of precipitation and relative instability, and the fact that in most cases a considerable period intervenes between the time of injection and the occurrence of symptoms has been adduced in support of the view that enzymes are present.
In other cases such changes cannot be detected, and the only evidence of their occurrence may be the associated symptoms. The very important work of Ehrlich on diphtheria toxin shows that in the molecule of toxin there are at least two chief atom groups - one, the " haptophorous," by which the toxin molecule is attached to the cell protoplasm; and the other the " toxophorous," which has a ferment-like action on the living molecule, producing a disturbance which results in the toxic symptoms. On this theory, susceptibility to a toxin will imply both a chemical affinity of certain tissues for the toxin molecule and also sensitiveness to its actions, and, furthermore, non-susceptibility may result from the absence of either of these two properties.
Metchnikoff and Bordet subsequently devised means by which a similar change could be produced in vitro, and analysed the conditions necessary for its occurrence.
Thus dittographies are frequent and lacunae of occasional occurrence, but the version is singularly free from the glosses and corrections of unscrupulous scribes.

Storms of extreme violence, accompanied by torrential rain, and in rare instances by hailstones, are of not uncommon occurrence.
The great Yashts are not of very frequent occurrence in the manuscripts: some of them, indeed, are already met with but seldom, and MSS.
The state of involuntary trance, sometimes mistaken for death, is a similar occurrence.
The occurrence of the words "Achademia Leonardi Vinci" on certain engravings, done after his drawings, of geometric "knots" or puzzle-patterns (things for which we have already learned his partiality), helped to give currency to this impression not only in Italy but in the North, where the same engravings were copied by Albrecht Diirer.
The epoch was characterized by cold wet climate, by the supposed existence of Man of the Olom type, that is, nearly as dolichocephalous as the Neanderthal type, but with superciliary ridges flat, and frontal bones high, and by the occurrence of the musk-ox, the horse, the cave-bear, Rhinoceros tichorhinus and the mammoth.
The frequent occurrence of more than two pollen-sacs and the equally common occurrence of additional ovules have been regarded by some authors as evidence in favour of the view that ancestral types normally possessed a greater number of these organs than are usually found in the recent species.
A point of anatomical interest is the occurrence in the vascular bundles of the cotyledons, scale-leaves, and elsewhere of a few centripetally developed tracheids, which give to the xylem-strands a mesarch structure such as characterizes the foliar bundles of cycads.
From an evolutionary point of view, it is of interest to note the occurrence of filicinean and cycadean characters in the maidenhair tree.
A raucaria Bidwillii, the occurrence of small foliage-leaves, which have functioned as bud-scales, at intervals on the shoots affords a measure of seasonal growth.
The occurrence of long and short shoots is a characteristic feature of many conifers.
The long linear leaves of some species of Podocarpus, in which the lamina is traversed by a single vein, recall the pinnae of Cycas; the branches of some Dacrydiums and other forms closely resemble those of lycopods; these superficial resemblances, both between different genera of conifers and between conifers and other plants, coupled with the usual occurrence of fossil coniferous twigs without cones attached to them, render the determination of extinct types a very unsatisfactory and frequently an impossible task.
The occurrence of buds in the axils of carpellary scales may, however, simply mean that buds, which are (C and D after Worsdell.) FIG.
A striking feature in the roots of several genera, excluding the Abietineae, is the occurrence of thick and somewhat irregular bands ofthickening on the cell-walls of the cortical layer next to the endodermis.
The presence of hypodermal fibres is another feature worthy of note, but the occurrence of these elements is too closely connected with external conditions to be of much systematic value.
The occurrence of short tracheids in close proximity to the veins is a characteristic of coniferous leaves; these elements assume two distinct forms - (I) the short isodiametric tracheids (transfusion-tracheids) closely associated with the veins; (2) longer tracheids extending across the mesophyll at right angles to the veins, and no doubt functioning as representatives of lateral veins.
It has been suggested that transfusion-tracheids represent, in part at least, the centripetal xylem, which forms a distinctive feature of cycadean leaf-bundles; these short tracheids form conspicuous groups laterally attached to the veins in Cunninghamia, abundantly represented in a similar position in the leaves of Sequoia, and scattered through the so-called pericycle in Pinus, Picea, &c. It is of interest to note the occurrence of precisely similar elements in the mesophyll of Lepidodendron leaves.
One of the bestknown anatomical characteristics of the genus is the occurrence of numerous spindle-shaped or branched fibres with enormouslythickened walls studded with crystals of calcium oxalate.

The idea of providing a university and free local schools as parts of a public school system occurs in the constitution of 1820 (and in the Acts of Congress that prepared the way for statehood), and the occurrence is noteworthy; but the real beginnings of the system scarcely go back further than 1850.
The ancient Bohemian chronicler Cosmas of Prague gives a very picturesque account of this semi-mythical occurrence.
If the spot spectrum is compared with that of the chromosphere it appears that the lines of most frequent occurrence in the latter are those least affected in the spot, and the high level chromospheric lines not at all; the natural interpretation is that the spot is below the chromosphere.
Of course we are unable to say whether such a region is an actuality in the sun, on the earth it is an exception and transient, but the greater the dimensions of the body the more probable is its occurrence.
Portions of his correspondence have been printed at various times, and inedited letters from him are of frequent occurrence in public libraries.
To one in his position this thought would be so very natural, that we need not hesitate to accept the fact of its occurrence as related in the oldest records.
In 1895 the single well then supplying Eastbourne was almost suddenly rendered unfit for use, and few years pass without some similar occurrence of a more or less serious kind.
A short time after the occurrence of the catastrophe the dam was visited by Dr W.
Pasteur that the occurrence of abiogenesis in the microscopic world was disproved as much as its occurrence in the macroscopic world.
This is not an infrequent occurrence, and arises from the tendency on the part of manufacturers to make balances so extremely sensitive that they are on the verge of in - stability.
Ordinary sulphuric acid, H 2 SO 4, may be prepared by dissolving sulphur trioxide in water, a reaction accompanied by a great evolution of heat; by the gradual oxidation of an aqueous solution of sulphur dioxide, a fact which probably explains the frequent occurrence of sulphuric acid in the natural waters rising in volcanic districts; or by deflagrating a mixture of sulphur and nitre in large glass bells or jars, absorbing the vapours in water and concentrating the solution.
His main discoveries, however, were in the field of physiology: he wrote valuable and suggestive papers on respiration, on the senses of bats, &c., while he made experiments (1768) to disprove the occurrence of spontaneous generation, showing in opposition to J.
If any prime occurs more than once, it is usual to write the number of times of occurrence as an index; thus 144=2X2X2X2X3X3=24 32.
Being accidental in their occurrence, they belonged to the auguria oblativa, and their interpretation was not a matter for the augurs, unless occurring in the course of some public transaction, in which case they formed a divine veto against it.
From its occurrence in so many of the lower vertebrates, the entepicondylar foramen of the humerus, as it is called, is regarded by Dr E.
The existence of paired caeca was previously known in a few armadillos and anteaters, but Dr Mitchell has shown that they are common in these groups, while he has also recorded their occurrence in the hyrax and the manati.
- That mammals have become differentiated from a lower type of vertebrates at least as early as the commencement of the Jurassic period is abundantly testified by the occurrence of the remains of small species in strata of that epoch, some of which are mentioned in the articles Marsupialia and Monotremata.
It is with the proboscidean suborder of the Ungulata to which the Sirenia are most nearly related; the nature of this relationship being described by Dr Andrews as follows: " In the first place, the occurrence of the most primitive Sirenians with which we are acquainted in the same region as the most generalized proboscidean, Moeritherium, is in favour of such a view, and this is further supported by the similarity of the brain-structure and, to some extent, of the pelvis in the earli
