"The only change observed in these tissues is a reflex edema, excited apparently by pressure on the ciliary nerves and, probably, irritation of the vaso-motor fibers of the sympathetic." Lachrymal Gland. Hyper secretion due to reflex irritation. Cornea.
Pneumonia. An inflammation affecting the air cells of the lungs. Any substance, which, when applied externally, or taken into the stomach or the blood, works such a change in the animal economy as to produce disease or death. Pons Varolii. Bridge of Varolius. The white fibers which form a bridge connecting the different parts of the brain, first described by Varolius.
This piece of wheat-straw contains more than sixty per cent. of silica or flint in its composition; so that, although a vegetable, it is nearly two-thirds composed of the hardest mineral substance we know of. You would scarcely believe that the fibers of the root of this plant were capable of dissolving, feeding upon, and digesting such a hard substance; but so it is." "It is very wonderful."
The influences which act upon fruit are external and internal. The external cause of dehiscence is drying. We can open or shut a fruit by drying or wetting it. The internal causes are related to the arrangement of the tissues, and we may say that the opening of fruit can be easily explained by the contraction of the ligneous fibers under drying influences.
The rough covering of the shell is woven into mats, brushes, ropes, and bags. The fibers of the leaves make a fine cloth. The dried leaves make a roof-thatch. The trunk makes foundation poles. The coconut itself is fruit and drink. When the white meat is dried, it is shredded for pastry and candy.
Under the influence of a warm south wind the sunlit hours became musical with the steady drip, drip of melting snow, while new life seemed to flow in the veins of the forest creatures grown gaunt under the pinch of hunger. Only Kagh, the porcupine, had remained full fed, but Kagh had been unusually blessed by a kind Providence, in that every tree held a meal for him in its soft inner fibers.
We cannot conceive of those relations as complex enough; we know, of course, that millions of nerve fibers lead from the periphery to the highest psychophysical apparatus in the cortex of the brain and that millions of fibers bring about the interrelation between these central stations, but we must never forget that millions of fibers also represent the outgoing paths and that they too lead down to lower central motor instruments which are again in numberless corelations.
The vessels, the fibers, and the substances which are their origins, are distinct from each other, and yet they act as one throughout the body, and they act together and on the instant.
=The Muscles.= The muscles form the lean meat in any animal. They make up about one half the weight of the body. Each muscle is a bundle of thousands of little threads held together by other finer threads, while the whole is surrounded by a thin sheet. Little bundles formed of several of these threads called fibers may be seen in a piece of cooked beef picked to pieces.
Through the dissolving iron mist of his striving, a sharp thought cleaved like an arrow. It was that after all he did not care. The religion of Success no longer held him as its devoutest worshiper. He was throwing the fibers of his life into the engine of toil, not because of moral duty, but because of moral pride. He meant to succeed in order to prove to himself that he had not been wrong.
