Such are the cells of glands, the cells of the salivary glands, which secrete the saliva, of the gastric glands, which secrete the gastric juice, of the intestinal glands, and the cells of the liver and sweat glands. Connective Tissue. This is the material, made up of fibers and cells, which serves to unite and bind together the different organs and tissues.
When these fibers contract, they draw forwards the attachment of the suspensory ligament of the lens, the pressure of which on the lens is consequently diminished. The elasticity of the lens causes it at once to bulge forwards, and it becomes more convex. The ciliary muscle is thus known as the muscle of accommodation, because it has the power to accommodate the eye to near and distant objects.
The spicules are joined together and cemented by a body that has been named "spongin," which has much the same chemical composition as silk, and, like silk, is very elastic. In some varieties of sponges, especially in the kinds which come into the market, the skeleton is almost entirely composed of fibers of pure "spongin."
When beef flank is cooked by boiling for two hours, the toughness of the fibers greatly increases during the first half hour of the cooking period, and then diminishes so that at the end of the cooking period the meat is found to be in about the same condition with respect to toughness or tenderness of the fibers as at the beginning.
Just exactly what changes take place in the muscle fibers of the heart in some of these fevers has not been decided.
In this region the Indians had never seen snow, and their land yielded three crops a year. Their pots and plates were of baked earth, and they kept corn in huge gourds, or in baskets woven of cane fibers. They knew nothing of beaver skins; their furs were the hides of buffaloes. Watermelons grew abundantly in their fields.
Wild wool is too fine to stand by itself, the fibers being about as frail and invisible as the floating threads of spiders, while the hairs against which they lean stand erect like hazel wands; but, notwithstanding their great dissimilarity in size and appearance, the wool and hair are forms of the same thing, modified in just that way and to just that degree that renders them most perfectly subservient to the well-being of the sheep.
There is little game in the country, yet they get a mountain sheep now and then or a deer, with their arrows, for they are not yet supplied with guns. They get many rabbits, sometimes with arrows, sometimes with nets. They make a net of twine, made of the fibers of a native flax. Sometimes this is made a hundred yards in length, and is placed in a half-circular position, with wings of sage brush.
The first is the application of intense heat to keep in the juices. This is suitable only for portions of clear meat where the fibers are tender. By the second method the meats are put in cold water and cooked at a low temperature. This is suitable for bone, gristle, and the toughest portions of the meat which for this purpose should be divided into small bits.
The strands of its nerve fibers and its groups of cells keep the various organs of the body properly coördinated, whereas in the second place, through the sensitive structures at the surface of the body, they receive the impressions from the outside world and so enable the organism to relate itself properly to its environment.
