The legs were represented by masses of cellular tissue and fat covered by skin which projected about an inch. He was intelligent, had a good memory, and exhibited considerable activity. He seemed to have had more than usual mobility and power of flexion of the lower lumbar region.
The animal organism unquestionably possesses the power of forming, from the constituents of its blood, the substance of its membranes and cellular tissue, of the nerves and brain, and of the organic part of cartilages and bones. But the blood must be supplied to it perfect in everything but its form that is, in its chemical composition.
The soft slimy plasson of the body of the moneron is generally called "protoplasm," and identified with the cellular matter of the ordinary plant and animal cells. But we must, to be accurate, distinguish between the plasson of the cytodes and the protoplasm of the cells. This distinction is of the utmost importance for the purposes of evolution.
The man goes to the fields, cuts down some stalks and, having removed the leaves, splits off the outer fiber layers from the cellular matter of the interior, using a bone knife for this purpose. This consists of a knife which rests on a wooden block. The handle turns on a pivot and the end is drawn upwards by means of a bent twig, or sapling, which acts as a spring.
His experimental observations appear to show that new bone is exclusively formed by the cellular elements or osteoblasts: these are found on the surface of the bone, lining the Haversian canals and in the marrow.
The blood is then pumped into general and systemic circulation, where it reaches all parts of the body, delivering nutrition and oxygen at a cellular level. On its return flow, a large proportion of the depleted blood is collected by the gastric, splenic and superior and inferior mesenteric veins that converge to form the large portal vein which enters the liver.
One of these insisted upon showing us an idol, which, from his description, should have been a rather beautiful piece. It turned out to be a very crudely-made head, wrought in coarse, cellular lava. Considering the material, the work was really fine; nor was it a fragment broken from the body, as there had never been more than what we saw.
In this disease the skin is dry from the increased absorption of the cutaneous lymphatics, the fat is absorbed from the increased absorption of the cellular lymphatics, the mucus of the lungs is too viscid to be easily spit up by the increased absorption of the thinner parts of it, the membrana sneideriana becomes dry, covered with hardened mucus, and at length becomes inflamed and full of aphthæ, and either these sloughs, or pulmonary ulcers, terminate the scene.
This inky fluid is a very remarkable secretion, produced in a bag that lies near the liver, and sometimes even embosomed in it, and communicating with the funnel by means of its own excretory duct. The interior of the bag is not a simple cavity; it is filled with a soft cellular or spongy substance in which the ink is diffused.
When the rays of the sun, which contain a great deal of heat, fall on any part of a frost-bitten plant, that part begins to expand so rapidly and violently that the cellular tissues are ruptured, and life is destroyed. What is more, the heat does not permeate equally and at once the parts affected by frost.
