During and after an attack of scarlet fever the patient "peels," that is, sheds an unusual amount of the seal; cells of the cuticle. The deeper and more active layer of the epidermis, the mucosum, is made up of cells some of which contain minute granules of pigment, or coloring matter, that give color to the skin.
CELLULOSE IN CEREALS. In addition to the five food substances that are found in all cereals, there is always present another material known as cellulose, which, as is pointed out elsewhere, is an indigestible material that occurs on the outside of all grains, as the bran covering, and covers the starch granules throughout the inside of the grain.
Colour, grey; sides with small granules; thumb short; chin-shields four; tail rounded with transverse series of small spines; femoral and preanal pores in a continuous line. Mus. Cat. p. 143; KELAART's Prod. Faun. Crocodile.
But Emile Berliner and Francis Blake finally came to the rescue with an excellent instrument, and the suggestion of an English clergyman, the Reverend Henry Hummings, that carbon granules be used on the diaphragm, made possible the present perfect instrument.
When the diaphragm moves toward the back of the transmitter it forces the carbon granules that are in the cup closer together; this lowers their resistance and allows more current from the battery to flow through them; when the pressure of the air waves is removed from the diaphragm it springs back toward the mouth-piece and the carbon granules loosen up when the resistance offered by them is increased and less current can flow through them.
Indeed I might compare the snow of the Arctic to the granules of sugar, without their saccharine sweetness, but with freezing cold instead; you can not make snowballs of it, for it is too thoroughly congealed, and when it is packed by the wind it is almost as solid as ice. It is from the packed snow that the blocks used to form the igloo-walls are cut.
The pus from the abscesses, upon cultivation, gave the long chains of granules not only that of the pleura, but that from the shoulders and a lymphatic of the uterus as well. An interesting thing, but easily understood, was that the blood from a vein in the arm and taken three-quarters of an hour after death was entirely sterile. Nothing grew from the Fallopian tubes nor the broad ligaments.
First, the busy little fairy Life in the active protoplasm; and secondly, the sun-waves. We have seen that it was by the help of the sunbeams that the green granules were made, and the water, carbonic acid, and nitrogen worked up into the living plant. And in doing this work the sun-waves were caught and their strength used up, so that they could no longer quiver back into space.
The whole hair consists of a very delicate outer case of wood, closely applied to the inner surface of which is a layer of semi-fluid matter, full of innumerable granules of extreme minuteness. This semi-fluid lining is protoplasm, which thus constitutes a kind of bag, full of a limpid liquid, and roughly corresponding in form with the interior of the hair which it fills.
However this obstruction may be brought about, whether by thickening of the iris root during dilatation of the pupil, pushing forward of the iris root by the larger ciliary processes of age, or the enlarged crystalline lens pressing on the ciliary processes; or by inflammatory adhesion of the iris to the filtration area; ballooning of the iris, or its displacement by traumatic cataract; or adhesion to the cornea after perforating ulcer in the secondary glaucomas; or whether the obstruction is due to the accumulation of experimental precipitates, as shown by Schreiber and Wengler, or possibly of pigment granules into Fontana's space; or a process of sclerosis closing the spaces by contraction of new-formed connective tissue, or the covering over with proliferating implanted epithelium following injury opening the anterior chamber; glaucoma follows impairment of this drainage space, and lessened outflow through it.
