Mosses when growing in tufts should be gathered just before the capsules have become brown, divided into small flat portions, and pressed lightly in drying paper.
34.-Female Janthina, with egg-float (a) attached to the foot; b, egg-capsules; c, ctenidium (gill-plume); d, cephalic tentacles.
The most remarkable feature of the genus is, however, the extraordinary development of the zygomatic arches of the skull, which are enormously expanded vertically, forming great convex bony capsules on the sides of the face, enclosing on each side a large cavity lined with mucous membrane internally, and communicating by a small opening with the mouth.
In diameter, and with the shoots or young branches more or less angular; the glossy deltoid leaves are sharply pointed, somewhat cordate at the base, and with flattened petioles; the fertile catkins ripen about the middle of June, when their opening capsules discharge the cottony seeds which have given the tree its common western name; in New England it is sometimes called the "river poplar."
In the middle of the body, where the limits of the somites can be checked by a comparison with the arrangement of the nephridia and the gonads, and where the ganglia are quite distinct and separated by long connectives, each ganglion is seen to consist of six masses of cells enclosed by capsules and to give off three nerves on each side.
Organs of hearing in the form of capsules containing otoliths have only been very rarely observed, apparently only in Metanemertini.
It is convenient to place in a small envelope gummed to an upper corner of the sheet any flowers, seeds or leaves needed for dissection or microscopical examination, especially where from the fixation of the specimen it is impossible to examine the leaves for oilreceptacles and where seed is apt to escape from ripe capsules and be lost.
During this process the capsules ripen, and are thus obtained in a perfect state.
Norman, Terebratulina caput-serpentis L., Terebratula (Gwynia) capsules Jeff., Magellania (Macandrevia) cranium Mull.,M.
Pacas may be distinguished from agoutis by their heavier and more compact build, the longitudinal rows of light spots on the fur, the five-toed hind-feet, and the peculiar structure of the skull, in which the cheek-bones are expanded to form large capsules on the sides of the face, each enclosing a cavity opening on the side of the cheek.
To Thomas Addison's descriptions of certain anaemias, and of the disease of the suprarenal capsules which bears his name, something has been added; and W.
The oil may be given in capsules, or in the form of an emulsion, with or without maltextract, or success may be obtained by adding, to every two drachms of the oil, ten minims of pure ether and a drop of peppermint oil.
Long with a rounded crenate outer edge and repeatedly forked veins; the sori (or masses of spore-capsules) are in the crenatures of the pinnules, and are protected by a kidney-shaped involucre.
ANGIOSPERMS. The botanical term "Angiosperm" (ayyeEov, receptacle, and o-71pua, seed) was coined in the form Angiospermae by Paul Hermann in 1690, as the name of that one of his primary divisions of the plant kingdom, which included flowering plants possessing seeds enclosed in capsules, in contradistinction to his Gymnospermae, or flowering plants with achenial or schizo-carpic fruits - the whole fruit or each of its pieces being here regarded as a seed and naked.
When flax is cultivated primarily on account of the fibre, the crop ought to be pulled before the capsules are quite ripe, when they are just beginning to change from a green to a pale-brown colour, and when the stalks of the plant have become yellow throughout about two-thirds of their height.
As a general rule the removal of the " bolls " or capsules by the process of rippling immediately follows the pulling, the operation being performed in the field; but under some systems of cultivation, as, for example, the Courtrai method, alluded to below, the crop is made up into sheaves, dried and stacked, and is only boiled and retted in the early part of the next ensuing season.
The best rippler, or apparatus for separating the seed capsules from the branches, consists of a kind of comb having, set in a wooden frame, iron teeth made of round-rod iron i ths of an inch asunder at the bottom, and half an inch at the top, and 18 in.
The skull, which must have consisted of hardened cartilage, exhibits pairs of nasal and auditory capsules, with a gill-apparatus below its hinder part, but no indications of ordinary jaws.
- Capsules of Jute Plants.
The capsules or seed-pods in the case of C. capsularis are globular, rough and wrinkled, while in C. olitorius they are slender, quill-like cylinders (about 2 in.
1, in which a and b show the capsules of C. capsularis and C. olitorius respectively.
77, draws a distinction between pn?aiwEcov, which he describes as an extract of the entire herb, and the more active Inros, derived from the capsules alone.
The petals fall in a few hours, and the capsules grow so rapidly that in a short time - generally from nine to fifteen days - the opium is fit for collection.
This period is known by the capsules yielding to pressure with the fingers, assuming a lighter green tint and exhibiting a kind of bloom called " cougak," easily rubbed off with the fingers; they are then about 12 in.
The whole of the operation must, of course, be completed in the few days - five to ten - during which the capsules are capable of yielding the drug: A cold wind or a chilly atmosphere at the time of collection lessens the yield, and rain washes the opium off the capsules.
The average amount of Turkish opium exported is 7000 chests, but in rare seasons amounts to 12,000 chests, but the yield depends upon fine weather in harvest time, heavy rains washing the opium off the capsules, and lessening the yield to a considerable extent.
Four varieties of poppy are distinguished - two with white flowers, large oval capsules without holes under their " combs " (stigmas) and bearing respectively yellow and white seed, and the other two having red or purple flowers and seeds of the same colour, one bearing small capsules, perforated at the top, and the other larger oval capsules not perforated.
The capsules are incised vertically, or in some districts vertical cuts with diagonal branches are made.
The male ducts often have glandular walls, secreting capsules or spermatophores within which the spermatozoa are packed for transference to the female.
The smoking of the seeds and capsules of henbane is noted in books as a somewhat dangerous remedy adopted by country people for toothache.
Iwanzov  has brought forward strong grounds for the latter view, pointing out that the cnidoblast has no contractile mechanism and that measurements show discharged capsules to be on the average slightly larger than undischarged ones.
Ct, Interlobular connective tissue forming the capsules of the lobules.
Bleaching, and the manufacture of bottle capsules, patent leather and other articles are carried on at Arcueil; and there are important stone-quarries.
The specimens should be collected when the capsules are just appearing above or in the colesule or calyx; if kept in a damp saucer they soon arrive at maturity, and can then be mounted in better condition, the fruit-stalks being too fragile to bear carriage in a botanical tin case without injury.
Cunningham that in Buccinum the egg-capsules are formed by this pedal gland and not by any accessory organ of the generative system.
Such horny egg-capsules doubtless have the same origin in all other species in which they occur, e.g.
Fusus, Pyrula, Purpura, Murex, Nassa, Trophon, Voluta, &c. The float of the pelagic Janthina, to which the egg-capsules are attached, probably is also formed by the secretion of the pedal gland.
Many Gastropoda deposit their eggs, after fertilization, enclosed in capsules; others, as Paludina, are viviparous; others, again, as the Zygobranchia, agree with the Lamellibranch Conchifera (the bivalves) in having simple exits for the ova without glandular walls, and therefore discharge their eggs unenclosed in capsules freely into the sea-water; such unencapsuled eggs are merely enclosed each in its own delicate chorion.
Egg-capsules are formed they are often of large size, have tough walls, and in each capsule are several eggs floating in a viscid fluid.
The brain con sists not only of a group of six capsules corre sponding to the archi cerebrum of the Oligo chaeta, but of a further mass of cells surrounding S S and existing below the alimentary canal, which can be analysed into five or six more separate ganglia.
As in all poplars, the catkins expand in early spring, long before the leaves unfold; the ovaries bear four linear stigma lobes; the capsules ripen in May.
In this well-known variety the young shoots are but slightly angled, and the branches in the second year become round; the deltoid short-pointed leaves are usually straight or even rounded at the base, but sometimes are slightly cordate; the capsules ripen in Britain about the middle of May.
