Kolbe, on the other hand, insists that the weevils are the most modified of all beetles, being highly specialized as regards their adult structure, and developing from legless maggots exceedingly different from the adult; he regards the Adephaga, with their active armoured larvae with two foot-claws, as the most primitive group of beetles, and there can be little doubt that the likeness between larvae and adult may safely be accepted as a primitive character among insects.
The generalized arrangement of the wing-nervure and the nature of the larva, which is less unlike the adult than in other beetles, distinguish this tribe as primitive, although the perfect insects are, in the more dominant families, distinctly specialized.

In some forms the coiling disappears in the adult, leaving the shell simply conical as in Patellidae, Fissurellidae, &c., and in some cases the shell is coiled in one plane, e.g.
In forms which are naked in the adult state, the shell falls off soon after the reduction of the velum, but in Cenia, Runcina and Vaginula the shell-gland and shell are not developed, and the young animal when hatched has already the naked form of the adult.
In those Euthyneura in which the shell is entirely absent in the adult, it is, except in the three genera Cenia, Runcina and Vaginula, developed in the larva and then falls off.
A few Euthyneura in which the shell is not much reduced retain an operculum in the adult state, e.g.
From the fact that Aplysia commences its life as a free-swimming veliger with a nautiloid shell not enclosed in any way by the border of the mantle, it is clear that the enclosure of the shell in the adult is a secondary process.

It is important here to note that Clausilia furnishes us with an exceptional instance of the continuity of the shell or secreted product of the primitive shell - sac with the adult shell.
This bilobed sac becomes entirely the liver in the adult; the intestine and stomach are formed from the pedicle of invagination, whilst the pharynx, oesophagus and crop form from the stomodaeal invagination ph.
The most important fact about them is that they disappear, and are in no way connected with the typical nephridium of the adult.

Moreover, the author goes on to remark that in adult birds trace of the origin of the sternum from five centres of ossification is always more or less indicated by sutures, and that, though these sutures had been generally regarded as ridges for the attachment of the sternal muscles, they indeed mark the extreme points of the five primary bony pieces of the sternum.
The points at issue between Cuvier and Etienne Geoffroy St-Hilaire before mentioned naturally attracted the attention of L'Herminier, who in 1836 presented to the French Academy the results of his researches into the mode Isidore of growth of that bone which in the adult bird he had already studied to such good purpose.
His only unfortunate contribution to entomology - indeed to zoology generally - was his theory of pre-formation, which taught the presence within the egg of a perfectly formed but miniature adult.
(Cattle food.) The adult weevils puncture the young flower-buds and deposit eggs; and as the grubs from the eggs develop, the bud drops.

No other intermediate stages have as yet been noticed between this arrangement and that of the Heteronemertini, in which a separate posterior brain-lobe receives a similar ciliated canal, and in which the oesophageal outgrowths have made their appearance and are coalesced with the nerve-tissue in the organ of the adult animal.
Two pairs of invaginations of B the skin, which originally are called the prostomial and metastomial disks, grow round the intestine, finally fuse together, and form the skin and mus- cular body-wall of the future Nemertine, which afterwards becomes ciliated, frees itself from the pilidium investment and develops into the adult worm without further metamorphosis.

The island was brought under the immediate administration of New South Wales; a chief magistrate, appointed by the governor of New South Wales, took the place of the elected magistrate, and an elected council of twelve elders superseded the general gathering of the adult population.
Suffrage is conferred upon all adult citizens of the United States (including women, 1910) who have lived in the state one year, in the county ninety days, and in the city, town, ward or precinct thirty days immediately preceding the election, and are able to read and speak the English language; Indians who are not taxed, idiots, insane persons and convicts are debarred.
The franchise is given to all adult white male British subjects.
The first chamber consists of the adult princes of the blood, two representatives of the Lutheran and one of the Roman Catholic Church, a representative of Leipzig university, the proprietor (or a deputy) of the Herrschaft of Wildenfels, a proprietor of the mediatized domains, two of Standesherrschaften, one of those of four estates in fee, the superintendent at Leipzig, a deputy of the collegiate institution at Wurzen, 12 deputies elected by owners of nobiliar estates, ten landed proprietors and five other members nominated by the king and the burgomasters of eight towns.

Well-organized continuation schools and systematic courses of lectures aim at providing the young soldier with a complete adult education.
CUCKOO-SPIT, a frothy secretion found upon plants, and produced by the immature nymphal stage of various plant-lice of the familiar Cercopidae and Jassidae, belonging to the homopterous division of the Hemiptera, which in the adult condition are sometimes called frog-hoppers.
They surround a region which is termed the peristome, and which contains in the centre the blastopore, which becomes the adult mouth.
The gastrula has now become an actinula, which may be termed the distinctive larva of the Cnidaria, and doubtless represents in a transitory manner the common ancestor of the group. In no case known, however, does the actinula become the adult, sexually mature individual, but always undergoes further modifications, whereby it develops into either a polyp or a medusa.
The internal structural differences are even more characteristic. In the hydropolyp the blastopore of the embryo forms the adult mouth situated at the extremity of the hypostome, and the ectoderm and FIG.
In the anthopolyp the blastopore is carried inwards by an in-pushing of the body-wall of the region of the peristome, so that the adult mouth is an opening leading into a short ectodermal oesophagus or stomodaeum, at the bottom of which is the blastopore.
For Streblocerus pygmaeus, grown under the same conditions, Sars observes: " This is perhaps the smallest of the Cladocera known, and is hardly more than visible to the naked eye," the adult female scarcely exceeding 0.25 mm.
14 (not to put a stumbling block before the blind) is the ground for cautioning a father against striking an adult child, and Deut, xxv.
The burrow of the young hamster is only about a foot in depth, while that of the adult descends 4 or 5 ft.
He has observed that in young specimens of Siren lacertina (the larva is still unknown) the gills are rudimentary and functionless, and that it is only in large adult specimens that they are fully developed in structure and function; he therefore concludes that the sirens are the descendants of a terrestrial type of batrachians, which passed through a metamorphosis like the other members of their class, but that more recently they have adopted a permanently aquatic life, and have resumed their branchiae by reversion.
In the genus Tejus the teeth of the adult become molar-like; and in Dracaena they are transformed into large, oval crushers, indicating strictly herbivorous habits, while most members of the family live upon animal food.
The culture of silk, flax, grapes (for wine-making) and fruits and cereals in general, and the manufacture of flour and of woollen, flannel and cotton fabrics, were carried on under a rule requiring every adult to labour 12 or 14 hours each day in field or mill.
He showed that from each individual shell of an ammonite the entire ancestral series may be reconstructed, and that, while the earlier shell-whorls retain the characters of the adults of preceding members of the series, a shell in its own adult stage adds a new character, which in turn becomes the pre-adult character of the types which will succeed it; finally, that this comparison between the revolutions of the life of an individual and the life of the entire order of ammonites is wonderfully harmonious and precise.
Hyatt went further and demonstrated that ancestral characters are passed through by successive descendants at a more and more accelerated rate in each generation, thus giving time for the appearance of new characters in the adult.
In his history of the Arietidae Hyatt points out that toward the close of the Cretaceous this entire group of ammonites appears to have been affected with some malady; the unrolled forms multiply, the septa are simplified, the ornamentation becomes heavy, thick, and finally disappears in the adult; the entire group ends by dying out and leaving no descendants.
The two apposed layers of endoderm in the cathammal area undergo complete fusion to form a single layer of epithelium, the endoderm-lamella of the adult medusa.
A parasitic mode of life is also seen in medusae of the genus Cunina during the larval condition, but the habit is abandoned, in this case, when the medusae become adult.

A falling birth-rate, a falling death-rate, and the increase in the number of adult immigrants, are presumably the chief causes of this difference.
In Wyoming, Colorado, Utah, Idaho and Washington universal adult suffrage prevails.
And still the rubrics of the English Prayer-Book direct that the person who is baptized as an adult is to "be confirmed by the bishop so soon of ter his baptism as conveniently may be."

Sometimes this gland is found in the young and not in the adult (Anodonta, Unio, Cyclas).
A very few have the power of swimming by opening and shutting the valves of the shell (Pecten, Lima); most can crawl slowly or burrow rapidly; others are, when adult, permanently fixed to stones or rocks either by the shell or the byssus.
7) set in the firm substance of the adult tubular shell, which has even replaced the ligament, so that the tube is complete.
The glochidium quits the gillpouch of its parent and swims by alternate opening and shutting of the valves of its shell, as do adult Pecten and Lima, trailing at the same time a long byssus thread.

Some of the families - the stone-flies, for example - have the young insect much like the adult, growing its wings visibly outside the thoracic segments, and active at all stages of its life.
Hagen not to be functional in the adult insect - they are merely survivals from the aquatic nymphal stage.
Some Embiidae are entirely wingless in the adult state, and it has been suggested that this is always the condition in the female sex.
Bottlenoses feed on cuttle-fishes and squills, and are practically toothless; the only teeth which exist in the adult being a small pair at the front of the lower jaw, concealed beneath the gum during life.
Cavity of body Cavity of cervix elevation in front of the pubic bones caused by a mass of fibrofatty tissue; the skin over it is covered by hair in the adult.
Both sexes carry lyrate horns; the shoulder-height of an adult male is about 30 in., and an average pair of horns measures 14 in.
Such organs are absent in Mollusca in the adult state, but a pair of nephridia usually occurs in the larva.
In existing forms the latter disappear in the adult.
Most remarkable is its resemblance to the adult form of the Wheel animalcules, or Rotifera, which retain the prae-oral ciliated band as their chief organ of locomotion and prehension throughout life.
They invariably disappear before the adult stage is reached, but their presence in the larva is evidence that the ancestral mollusc possessed a pair of true nephridia quite distinct from the coelomic excretory organs, which are so characteristic of existing forms in the adult condition.
As regards the recent forms, the dentition in the fully adult animal consists only of incisors and cheek-teeth, the formula being i.
The average fatal dose for an adult is i 2 grs., but death has resulted in twenty minutes from 2 grain.
Taken as a whole, the finches, concerning which no reasonable doubt can exist, are not only little birds with a hard bill, adapted in most cases for shelling and eating the various seeds that form the chief portion of their diet when adult, but they appear to be mainly forms which predominate in and are highly characteristic of the Palaearctic Region; moreover, though some are found elsewhere on the globe, the existence of but very few in the Notogaean hemisphere can as yet be regarded as certain.
The tayra is, when adult, black beneath and on the legs, and not uncommonly has a considerable quantity of greyish hair on the head.
Finally the larva of one of the Bornean Mantidae, which is a floral simulator in its pupal and adult stages, closely resembles in its black and red coloration the larva of the stinking and warningly coloured bug Eulyes amoena.
The adult bird in the wild state is exceedingly shy and difficult of approach, and, owing to its great fleetness and strength, is rarely if ever caught.
C. Taylor (Ibis, 1878, p. 372) saw an adult which had been killed near Lake Menzal in 1877.
The annual baptisms of adult heathen are 190,000; those of heathen children at the point of death, 450,000.
The seeds contain a toxic substance, which makes them actively poisonous; so much so that three have been known to kill an adult.
The tegmentum is much reduced in Acanthochiton, and absent in the adult Cryptochiton.
gland, consisting of two lobes which are symmetrical in the young animals, but in the adult the right lobe is anterior and smaller.
Just behind the ciliated ring is a pair of larval eyes which disappear in the adult; these correspond to the cephalic eyes of Lamellibranchs.
An ectodemic invagination forms a large mucous gland on the foot, which is more or less atrophied in adult life.
And although embryology seems to prove that the Neomeniomorphs are derived from forms with a series of shell-valves, nevertheless it seems probable that the calcareous spicules which alone are present in adult Aplacophora preceded the solid shell in evolution.
In this case there should be only one pair of coelomoducts in the adult, the pair of true nephridia which should also occur being represented by the larval nephridia.
Notwithstanding the war carried on against the jay, its varied cries and active gesticulations show it to be a sprightly bird, and at a distance that renders its beauty-spots invisible, it is yet rendered conspicuous by its cinnamon-coloured body and pure white tail-coverts, which contrast with the deep black and rich chestnut that otherwise mark its plumage, and even the young at once assume a dress closely resembling that of the adult.
Specimens in the museum at Tervueren near Brussels show that in fully adult males the horns are subtriangular and inclined somewhat backwards; each being capped with a small polished epiphysis, which projects through the skin investing the rest of the horn.
The usual colour of the adult is yellowish-brown, but it may vary from a deep red or chestnut brown to an almost silvery grey.
After the spread of Christianity among the Romans, however, foeticide became equally criminal with the murder of an adult, and the barbarian hordes which afterwards overran the empire also treated the offence as a crime punishable with death.
Adult foreigners visiting the country are also liable to be attacked, and women, especially, rarely escape disfigurement if they stay in the country for any length of time.
The tadpoles grow to a large size considering that of the adult, the body equalling in size a sparrow's or even a small pigeon's egg, and they often remain more than a year in that condition.
They continue to grow, and to thrust out new branches and to lengthen existing branches, for many years far into adult life.
Could we assume that there is in the adult man reflex machinery which is of higher order than the merely spinal, which employs much more complex motor mechanisms than they, and is connected with a much wider range of sense organs; and could we assume that this reflex machinery, although usually associated in its action with memorial and volitional processes, may in certain circumstances be sundered from these latter and unattendant on them - may in fact continue in work when the higher processes are at a standstill - then we might imagine a condition resembling that of the somnambulistic and cataleptic states of hypnotism.
Such ciliary motion is known in the adult condition of the cells of Volvocaceae, but where this is not the case the reproductive cells are endowed with motility for a brief period.
This peculiar product of germination, which intervenes between the oospore and the adult form, is the proembryo.
It will be remembered that in M usci, the asexual spore somewhat similarly gives rise to a protonema, from which the adult plant is produced as a lateral bud.
Mottier's observation has been confirmed by Lloyd Williams, who has shown, moreover, that the single number occurs in germlings from the tetraspore, and also in the adult stages of all sexual plants, while the double number occurs in germlings from the oospore, and in adult stages of all asexual plants.
The Bovidae are thus brought into nearer relationship with the American prongbuck (the only living ruminant which sheds its horn-cover in the adult condition) than has generally been supposed.
- Skull of Chinese Water-Deer, Hydrelaphus inermis (adult male), a Deer without Antlers, but with largely developed upper canine teeth.
As regards their distinctive features, the antlers are of a complex type and situated close to the occipital ridge of the skull, and thus far away from the sockets of the eyes, with the brow-tines in adult males palmated, laterally compressed, deflected towards the middle of the face, and often unsymmetrically developed.
And similarly in the development of a complicated organism, the suppression or doubling of a single cell or group of cells may bring about striking differences in the symmetry of the adult, or the reduction or increase in the number of metameric organs.
A slight change in the structure or activity of a gland, by altering the internal secretion, may produce widespread alterations even in an adult organism; and we have good reason to suppose that, if compatible with viability, such minute changes would have even a greater ultimate effect if they occurred in an embryo.
The interplay of extrinsic and intrinsic factors also differs with the age of the organism affected: the more nearly adult it may be, the more direct appears to be the influence of the environment; the more nearly embryonic the organism may be, the less direct is the result of a force impressed from without.
The various parts of a living organism affect each other in adult life and during growth.
The earliest Anabaptists of Zurich allowed that the Picardi or Waldensians had, in contrast with Rome and the Reformers, truth on their side, yet did not claim to be in their succession; nor can it be shown that their adult baptism derived from any of the older Baptist sects, which undoubtedly lingered in parts of Europe.
The young, which are hatched after about four weeks' incubation, look very different from the adult.
The dentition in the adult is i.
In the Miocene Agriochoerus, which typifies a second sub-family (Agriochoerinae), there is no gland-pit in the skull, of which the orbit is open behind; while the upper incisors are wanting in the adult and the terminal toe-bones are claw-like rather than of the hoofed type.
In the adult aquatic stage the alimentary canal shows signs of degeneration, and it seems probable that in this stage Gordian worms take no food.
In the adult male the lateral body-cavities are absent.
The oasis contains many groves of date palms, there being over 60,000 adult trees in 1907.
As his son Moawiya who succeeded him was certainly adult (the accounts vary between 17 and 23), the latter date seems to be preferable.
When Merwan entered Damascus this man testified that the sons of Walid II., who had just become adult, had named Merwan successor to the Caliphate, and was the first to greet him as Prince of the Believers.
Also under state control are the home for care and training of feeble-minded children, at Eldridge, Sonoma county; the institution for the deaf and the blind at Berkeley, and the home of mechanical trades for the adult blind at Oakland.
In confinement these apes (of which adult specimens have been exhibited in Calcutta) appear very slow and deliberate in their movements; but in their native forests they swing themselves from bough to bough and from tree to tree as fast as a man can walk on the ground beneath.

New clefts continue to form at the posterior end of the pharynx during the adult life of the animal.
The larvae swim normally like the adult or suspend themselves by their flagella (not shown in the figures) vertically in mid-water.
The adult form is achieved by metamorphosis, which cannot be further described here.
An admirable discrimination of the larval and adult characters of the genus Sergestes has been given by H.
eminent naturalists were still debating whether in this group there were eyes or no eyes, whether the eyes were stalked or sessile, whether the animals observed were larval or adult.
are absent or vestigial in all other insects; and, in most genera, by the presence in the adult of abdominalappendagesused for locomotion, these latter varying in number from one to nine pairs.
On the contrary, the effect of the inflow of adult migrants is very marked, as is to be expected, in the returns for the new countries, such as the United States, Canada and Australasia.
In Scandinavia, and perhaps in Italy, the rate may be affected by the emigration of adult males, but the later columns of the table indicate that this is not the cause of the low rate in Ireland, which appears to be mainly due to abstinence from marriage at the ages specified.
The cessation of assisted immigration early in the life of the present generation is alleged to have had considerable influence upon the rate, in Victoria, at least, owing to the curtailment of the supply of adult women of the more conceptive ages and the ageing of those who had reached the country at an earlier date.
So far as adult life is concerned this superior vitality is no doubt attributable to comparative immunity from the risks and hardships to which men are exposed, as, also, to the weaker inclination of women towards intemperance of different kinds.
Almost every tribe has its initiation ceremonies, and in many tribes adult life may almost be described as a continuous initiation.
We must transport as large a number as possible of adult healthy individuals to some intermediate station, and increase them as much as possible for some years.

This valve, in the young oyster, is attached to some object on the sea-bottom; in the adult it is sometimes attached, sometimes free.
The embryos having then reached the condition of "trochospheres" escape from the mantle cavity and swim about freely near the surface of the water among the multitude of other creatures, larval and adult, which swarm there.
Professor Mobius is of opinion that oysters over twenty years of age are rare, and that most of the adult Schleswig oysters are seven to ten years old.
(3023 10), the son of Narses, the magnates imprisoned or put to death his adult sons, one of whom, Hormisdas, later escaped to the Romans, who used him as a pretender in their wars.
When the thyroid gland is absent in children, not only is the expression of the face dull and heavy as in the adult, but the growth both of body and mind is arrested, and the child remains a stunted idiot.
In the Transvaal and Orange Free State provinces the franchise is restricted to white adult male British subjects.
The adult plumage is of a uniform black, with the exception of a frill of white feathers nearly surrounding the base of the neck, and certain wing feathers which, especially in the male, have large patches of white.
The species of fish which can be kept successfully in captivity throughout their lives from egg to adult is exceedingly limited in number.
The eggs are collected either by "stripping" them from the mature adult immediately after capture, or by keeping the adults alive until they are ready to spawn, and then stripping them or by keeping them in reservoirs of sea-water and allowing them to spawn of their own accord.
to Anthozoa - this group abandoned its power of adult locomotion by swimming.
It is only to fully adult males that this description applies.
In 1906 it was estimated of Chinese smoked opium, or 27% of adult males; but during1908-1910the consumption of opium is believed to have diminished by about one-third.
No adult Scyphomedusae are known to reproduce themselves by budding or by any method other than the sexual one.
The sixteen tentacles of the scyphistoma disappear, and in the place of the four perradial and four interradial tentacles, the eight tentaculocysts of the adult are formed as outgrowths of the subumbral margin, independently of the tentacles of the scyphistoma (Friedemann).
(After Claus.) by Friedemann (3), a recent investigator of the subject, that the infundibular cavities appear late in the scyphistoma and have no relation either to the septal muscles or to the subgenital cavities of the adult.
Thus in Pelagia the scyphistoma-stage is free-swimming and changes directly into the ephyra, which in its turn grows into the adult form.
On the other hand, such a form as Lucernaria or Haliclystus may be regarded simply as a scyphistoma which has become adult and mature.
The comparison of the metagenetic type of development, such as that of Aurelia, with the more primitive genera of Scyphomedusae, indicates clearly that the scyphistoma and ephyra are recapitulative larval stages which are represented by the adult forms of primitive genera, making such allowances as are necessary when comparing adult and larval forms. The metagenesis has arisen through the scyphistoma-larva acquiring the power of larval proliferation by budding.
Vote by ballot was troduced; the number of members in the assembly was creased to 80, and the franchise was granted to every adult male after six months' residence in any electoral area.
The " growing point " of the trunk is, in fact, situated in front of this region, and, when the full number of somites has been reached, the unsegmented part remaining forms the telson of the adult.
2, Nebalia bipes (one side of 5, Branchipus stagnalis: a, adult carapace removed).
The most peculiar modification, perhaps, is that found in the Cirripedia (Thyrostraca), in the larvae of which the antennules develop into organs of attachment, bearing the openings of the cement-glands, and becoming, in the adult, involved in the attachment of the animal to its support.
The antennae (second antennae) are of special interest on account of the clear evidence that, although preoral in position in all adult Crustacea, they were originally postoral appendages.
This form is retained, with little alteration in some adult Copepoda, where the biramous " palp " still aids in locomotion.
Thus, in the Phyllopoda, the antennal gland develops early and is functional during a great part of the larval life, but it ultimately atrophies, and in the adult (as in most Entomostraca) the maxillary gland is the functional excretory organ.
In the Decapoda, where the antennal gland alone is well-developed in the adult, the maxillary gland sometimes precedes it in the larva.
Copepoda) it forms the sole organ of vision in the adult.
In the Malacostraca it is absent in the adult, or persists only in a vestigial condition, as in some Decapoda and Schizopoda.
The majority of the Crustacea are hatched from the egg in a form differing more or less from that of the adult, and pass through a series of free-swimming larval stages.
12) has an oval unsegmented body and three pairs of limbs corresponding to the antennules, antennae and mandibles of the adult.
The limb-buds early become bilobed and grow out into typical biramous appendages which gradually assume the characters found in the adult.
The course of development here outlined, in which the nauplius gradually passes into the adult form by the successive addition of somites and appendages in regular order, agrees so well with the process observed in the development of the typical Annelida that we must regard it as being the most primitive method.
13, B), differing widely from the nauplius in form, and possessing all the appendages of the adult.
We need only mention the Mysis-stage (better termed Schizopodstage) found in many Macrura (as, for example, the lobster), which differs from the adult in having large natatory exopodites on the thoracic legs.
The barnacles and their allies, forming the group Cirripedia or Thyrostraca, sometimes treated as a separate sub-class, are distinguished by being sessile in the adult state, the larval antennules serving as organs of attachment, and the antennae being lost.
The shell-gland is formed on the dorsal surface, and the mantle arises as two lateral lobes which afterwards unite by their ventral edges to form the tubular mantle of the adult.
The mesoderm becomes segmented, and the parapodia subsequently develop from before backwards; but almost all internal traces of segmentation are lost in the adult.
PROBOSCIS-MONKEY, a large, long-tailed, red Bornean species characterized by the extraordinary prolongation of the nose of the adult male, which hangs, however, down in front of the upper lip and does not stand straight out from the face in the manner commonly represented in pictures.
The absolute capacity of the cranium of the gorilla is far less than that of man; the smallest adult human cranium hardly measuring less than 63 cub.
The leading characters of antlers are described under Pecora, but these structures may be defined somewhat more fully in the following passage from the present writer's Deer of all Lands:- " Antlers are supported on a pair of solid bony processes, or pedicles, arising from the frontal bones of the skull, of which they form an inseparable portion; and if in a fully adult deer these pedicles be sawn through, they will generally be found to consist of solid, ivory-like bone, devoid of perceptible channels for the passage of blood-vessels.
Although a few living species have the antlers in the form of simple spikes in the adult male, in the great majority of species they are more or less branched; while in some, like the elk and fallow-deer, they expand into broad palmated plates, with tines, or snags, on one or both margins.
Indeed, no living deer shows such primitive spikelike antlers in the adult, and it is doubtful whether such a type is displayed by any known extinct form, although many have a simple fork.
- Antlers rounded, usually with five or more tines, generally including a bez (second), and always a trez (third); coat of adult generally unspotted, with a large lightcoloured disk surrounding the tail; young, spotted.
- Antlers smaller and simpler, four-tined, with a trez (third), but no bez (second); coat of adult spotted, at least in summer, with a white area bordered by black in the region of the tail, which is also black and white.
- Antlers without a bez, but with a trez-tine, above which the beam is more or less palmated, and generally furnished with numerous snags; coat of adult spotted in summer, uniform in winter, with black and white markings in the region of the tail similar to those of Pseudaxis; young, spotted.
- Antlers flattened or rounded, without bezor trez-tine, the beam dichotomously forking, and one or both branches again forked, so that the number of tines is at least four; brow-tine forming a right angle or a continuous curve with the beam; coat of adult generally more or less uniform, of young spotted.
The first leaves borne on the seedling axis are often scalelike, and these are followed by two or more larger laminae, which foreshadow the pinnae of the adult frond.
The bundles from the cotyledons pursue a direct course to the stele of the main axis, and do not assume the girdle-form char acteristic of the adult plant.
Another departure from the normal is that in which the juvenile or seedling form of shoot persists in the adult tree; the numerous coniferous plants known as species of Retinospora are examples of this.
Pinus) as many as fifteen; these leaves are usually succeeded by foliage-leaves in the form of delicate spreading needles, and these primordial leaves are followed, sooner or later, by the adult type of leaf, except in Retinosporas, which retain the juvenile foliage.
In addition to the first foliage-leaves and the adult type of leaf, there are often produced leaves which are intermediate both in shape and structure between the seedling and adult foliage.
One of the best known examples is the Chinese juniper (Juniperus chinensis), in which branches with spinous leaves, longer and more spreading than the ordinary adult leaf, are often found associated with the normal type of branch.
These projections and ridges may be homologous with the seminiferous scale of the pines, firs, cedars, &c. The simplest interpretation of the cone of the Abietineae is that which regards it as a flower consisting of an axis bearing several open carpels, which in the adult cone may be very small or large and prominent, the scale bearing the ovules being regarded as a placental outgrowth from the flat and open carpel.
m.-, but in fully adult animals most ofthe front teeth were shed.
Pentelikon, Attica, shows the absence in the adult state of upper and lower incisors and upper canines, much the same condition being indicated in an Indian skull.
The total number of adult immigrants by sea, however, steadily increased from 11,559 in 1891 to 3 8,669 in 1896, while during the same period the number of departures by sea only increased from $415 to 17,695, and most of this increase took place in the last year.
But from 1896 onwards the uncertainty of the political position caused a falling off in the number of immigrants, while the emigration figures still continued to grow; thus in 1900 there were 2 9, 848 adult arrivals by sea, as compared with 21,163 departures.
The mesenteries second in order of formation form the sulcular directives, those fourth in order of formation form with the fifth the sulculo-lateral couples of the adult.
C, Diagram showing the arrangement of mesenteries in an adult Zoanthid.
ment of the adult mesenteries and in the order of development of the first cycle.
There are, however, several groups of Zoantharia in which the mesenterial arrangement of the adult differs widely from that just described.
In the Cerianthidea, as in the Zoanthidea, much as the adult arrangement of mesenteries differs from that of Actinia, the derivation from an Edwardsia stock is obvious.
Those of the Armenians and Syrians who have retained adult baptism use rivers alone at any time of year.
The rubrics of the MSS., it is true, enjoin total immersion, but it only came into general vogue in the 7th century, " when the growing rarity of adult baptism made the Gr.
In the West, however, the sacrament has been saved from becoming merely magical by the rite of confirmation or of reception of the Spirit being separated from the baptism of regeneration and reserved for an adult age.
The general practice for many years past among naturalists has been to restrict the terms "Insecta" and "insect" to the class of Arthropods with three pairs of legs in the adult condition: bees, flies, moths, bugs, grasshoppers, springtails are "insects," but not spiders, centipedes nor crabs, far less earthworms, and still less slugs, starfishes or coral polyps.
The daily activities of the great mass of the adult population, in countries where commodities are sold at definite prices for definite quantities, include calculations which have often to be performed rapidly, on data orally given, and leading in general to results which can only be approximate; and almost every branch of manufacture or commerce has its own range of applications of arithmetic. Arithmetic as a school subject has been largely regarded from this point of view.
There are also an adult probation law and a juvenile court law, the latter applying to every county in the state.
MacBride (op. cit.), who has insisted that in the fixed stage of the developing starfish, Asterina, the relations of these plates to the stem are quite different from those which they bear in the developing and adult crinoid.
First, as already mentioned, it outlines the general features of the Dipleurula; secondly, it indicates the way in which this free-moving form became fixed, and how its internal organs were modified in consequence; but when we seek, thirdly, for light on the relations of the classes, we find the features of the adult coming in so rapidly that such intermediate stages as may have existed are either squeezed out or profoundly modified.
In some of these respects the Dipleurula may have diverged from the ancestor of Enteropneusta and of other animals, but it could not as yet have been recognized as echinodermal by a zoologist, for it presented none of the structural peculiarities of the modern adult echinoderm.
Top columnal a persistent proximale, often fusing with IBB, which are frequently atrophied in the adult.
P. Sladen, who divided the Euasterida into two orders: (I) Phanerozonia, with marginals large and highly developed, the supero-marginals and inferomarginals contiguous, with papulae confined to the dorsal surface, with ambulacrals well spaced and usually broad, adambulacrals prominent in the mouth-skeleton, with pedicellariae sessile; (2) Cryptozonia, with marginals inconspicuous and somewhat atrophied in the adult, the supero-marginals separated from the inferomarginals by intercalated plates, with papulae distributed over the whole body, with ambulacrals crowded and narrow, either ambulacrals or adambulacrals prominent in the mouth-skeleton, with pedicellariae stalked or sessile.
In the Argasidae the anterior portion of the dorsal surface of the body is extended forwards above the capitulum, so that this structure is concealed from above; the integument is fairly uniformly granular or coriaceous above and below; the palpi are simple and unmodified; there is no sucker beneath the claws in the adult, and there is only a slight structural difference between the sexes.
The adult secures a host in the same way as the young.
From the foregoing epitome which applies to many species, Rhipicephalus appendiculatus for example, it is evident that every individual tick has to find a host on three occasions, namely, as larva, nymph and adult.
transforms the larva into the nymph takes place on the host, and in Margaropus annulatus the transformation of larva into nymph and nymph into adult is effected without the temporary sojourn on the ground.
It was actually provoked by the unwise and unjust poll-tax of one shilling a head on all adult persons, voted by the parliament of Northampton in November 1380.
The peasantry defended themselves by the simple device of understating the numbers of their families; the returns made it appear that the adult population of England had gone down from 1,355,000 to 896,000 since the poll-tax of 1379.
Adult monotremes are in like case, although the duckbilled platypus (Ornithorhynchus) has teeth when young on the sides of the jaws.
About i 5% of the adult population belong to the order of Akils.
These books record doctrinal instruction given, for practical ends, to laymen of adult years who were candidates for baptism.
The Catechetical school was primarily meant for instructing adult inquirers into Christianity.
Diprosthomerous in the adult condition, though embryologically the appendages of somite II and the somite itself are, as here drawn, not actually in front of the mouth.
It is practically an excalated somite, having no existence in the adult.
The somites of the abdomen all may carry rudimentary appendages in the embryo, and some of the hinder somites may retain their appendages in a modified form in adult life.
Terminal telescoping of the abdominal somites and excalation may occur in the adult, reducing the obvious abdominal somites to as few as eight.
For the real question is not about the time when ideas entered the mind, but " whether the constitution of man be such that, being adult and grown up, the ideas of order and administration of a God will not infallibly and necessarily spring up in him."
The upper chamber (Standesherren) is composed of adult princes of the blood, heads of noble families from the rank of count (Graf) upwards, representatives of territories (Standesherrschaften), which possessed votes in the old German imperial diet or in the local diet; it has also members (not more than 6) nominated by the king, 8 members of knightly rank, 6 ecclesiastical dignitaries, a representative of the university of Tubingen, and of the technical high school of Stuttgart, 2 representatives of commerce and industry, 2 of agriculture, and i of handicrafts.
PHORONIDEA, a zoological order, containing a single genus Phoronis, which is known to be of practically world-wide distribution, while there are many records of its larva, Actinotrocha, from localities, where the adult has not been found.
These associations of individuals can hardly be the result of the metamorphosis of a corresponding number of larvae, but are probably due to a spontaneous fragmentation of the adult animals, each such fragment developing into a complete Phoronis (De Selys-Longchamps).
The eggs of Phoronis are small and usually undergo their early development attached to the tentacles of the adult.
An oblique septum which follows the bases of the tentacles and corresponds with that of the adult animal divides the body-cavity into two portions.
The praeseptal cavity is a vascular space, since it is in free communication with the dorsal vessel of the larva, and it persists in part as the two lophophoral vascular crescents of the adult.
This view of the surfaces is, however, disputed by De Selys-Longchamps, who regards the aboral extremity of the adult as the posterior end.
There is, however, a considerable amount of resemblance between the lophophore of Phoronis australis, with its spirally twisted ends, and that of a typical Brachiopod; nor do the structural details of the adult Brachiopods forbid the view that they may be related to Phoronis.
The epistome of the adult Phoronis cannot well be the proboscis since its cavity is continuous with the lophophoral coelom, and because the praeoral hood of Actinotrocha is entirely lost at the metamorphosis.
At last Oedipus guessed correctly that it was man; for the child crawls on hands and feet, the adult walks upright, and the old man supports his steps with a stick.
In 1885 a serious disaster befell the islanders, a lifeboat which went to take provisions to a ship in the offing was lost with all hands - fifteen men - and only four adult males were left on the island.
Upon hatching, the young, which differ from the adult in possessing long antennae and a pair of powerful fossorial anterior legs, fall to the ground, burrow below the surface, and spend a prolonged subterranean larval existence feeding upon the roots of vegetation.
They are viviparous; the young are fully formed at birth, and differ from the adult only in size and colour.
These pits are eventually closed, and form the hollow ventral appendages of the suprapharyngeal ganglia of the adult (fig.
This red colour differs from the colour of the adult in being soluble in spirit.
The genus Peripatus, so far as adult conformation is concerned, is a very homogeneous one.
Most of the adult males are engaged in it.
Yarrell proved conclusively that Donovan's opinion was founded upon an error; unfortunately he contented himself with comparing whitebait with the shad only, and in the end adopted the opinion of the Thames fishermen, whose interest it was to represent it as a distinct adult form; thus the whitebait is introduced into Yarrell's History of British Fishes (1836) as Clupea alba.
The fry of fishes is used as an article of diet in almost every country: in Germany the young of various species of Cyprinoids, in Italy and Japan the young of nearly every fish capable of being readily captured in sufficient numbers, in the South Sea Islands the fry of Teuthis, in New Zealand young Galaxias are consumed at certain seasons in large quantities; and, like whitebait, these fry bear distinct names, different from those of the adult fish.
