It penetrates every solid tissue of the system, as may be known by puncturing any part of the body with even a pin, when blood is sure to follow. If it be ex- amined with a micro- scope when freshly drawn, it appears to be made up of a transparent liquid called the Serum or Plasma, and a num- ber of minute circular bodies, mostly of a red color, called corpuscles, or minute bodies. This fluid is found, on analy- sis, to be made up of water, albumen, fibrin, and several salts, some of which are found in crystals, as is seen in the cut. After it has been drawn from the body a considerable time, it separates into a thickened mass called Coagulum, made up of Fig. 225. fibrin and the corpuscles, while the serum with the albumen still remains as a transparent liquid. The Red Corpuscles prove to bj flattened discs with both surfaces slightly concave, and measuring about 3 sVoth of an inch in diameter, and are in reality nothing but a cell, that is a bag or sac containing a fluid composed of the two proximate principles globuline and hematine. Besides the red corpuscles, there exists another kind in the blood known as the White or Colorless Corpus- cles. They are by no means so abundant, when the body is What is its appearance under the microscope ? How does it conduct itself after stand- ing a while in an open vessel? Describe the Eed Corpuscles. Describe the White Cor- puscles.
