These corpuscles are little cells of the body, which in shape and behavior are almost exactly like an ameba a tiny "bug," seen only under the microscope, that lives in ditch-water. Under the microscope the white corpuscles look like little round disks, about one-third larger than the red corpuscles, and with a large kernel, or nucleus, in their centre.
I, Vegetation in the BLOOD of ague. J, Vegetation in the urine of ague during paroxysm. K, L, M, Vegetation in the urine of chronic cases of severe congestive type. N, Vegetation in BLOOD of Panama fever; white corpuscles distended with spores of Gemiasma. O, Gemiasma alba. P, Gemiasma rubra. Q, Gemiasma verdans. R, Gemiasma alba.
A gay time of it these youngsters have on the very banks of a stream that is bringing down to them every minute stores of fresh air in the round, red corpuscles of the blood, and a constant stream of suitable food in the serum. But it is not all pleasure, for every one of them is hard at work."
As with the Army ants, the flowing lines of leaf-cutters always brought to mind great arteries, filled with pulsating, tumbling corpuscles. When an obstruction appeared, as a fallen leaf, across the great sandy track, a dozen, or twenty or a hundred workers gathered like leucocytes and removed the interfering object.
According to this Notion it may be said, that the Corpuscles that make up the Beams of Light, whether they be Solary Effluviums, or Minute Particles of some Ætherial Substance, Thrusting on one another from the Lucid Body, do, falling on Black Bodies, meet with such a Texture, that such Bodies receive Into themselves, and Retain almost all the Motion communicated to them by the Corpuscles that make up the Beams of Light, and consequently Reflect but Few of them, or those but Languidly, towards the Eye, it happening here almost in like manner as to a ball, which thrown against a Stone or Floor, would Rebound a great way Upwards, but Rebounds very Little or not at all, when it is thrown against Water, or Mud, or a Loose Net, because the Parts yield, and receive into themselves the Motion, on whose Account the Ball should be Reflected Outwards.
"Is it one of the corpuscles of space which our projectile holds in its radius of attraction, and which will accompany it as far as the moon?" "What I am astonished at," answered Nicholl, "is that the specific weight of this body, which is certainly superior to that of the bullet, allows it to maintain itself so rigorously on its level."
"I conjecture that the atmospherical air consists of three different kinds of corpuscles," he says; "the first, those numberless particles which, in the form of vapors or dry exhalations, ascend from the earth, water, minerals, vegetables, animals, etc.; in a word, whatever substances are elevated by the celestial or subterraneal heat, and thence diffused into the atmosphere.
Its color varies from bright red in the arteries and when exposed to the air, to various tints from dark purple to red in the veins. The color of the blood is due to the coloring constituent of the red corpuscles, hæmoglobin, which is brighter or darker as it contains more or less oxygen. Blood Corpuscles of Various Animals.
The blood, flowing through the minute cavities containing these cells, carries those that have been loosened out into the blood stream. Nuclei appear in the red corpuscles at the time of their formation, but these quickly separate and, according to some authorities, form the blood platelets.
The net results of laboratory investigation, according to the French doctors, is that the mycetozoic malarial bacillus, the microbe of paludism, is amoeboid in its movements, acting on the red corpuscles, leaving nothing of them but the dark pigment found in the skin and organs of malarial subjects.
