Of these substances the serum contains the water, albu- 

 men and salts, the analysis of which by the same chemist 

 is in 1000 parts: Water, 906; Albumen, *78; Animal Matter, 

 soluble in Water and Alcohol, 1.69; Albumen, combined 

 with Soda, 2.10; Crystallizable Fatty Matter, 1.20; Oily 

 Matter, 1; Hydrochlorate Soda and Potassa, 6; Sub. Carb., 

 Phosphat. Sodae and Sulphat. Potassae, 2.10; Phosphate of 

 Lime, Magnesia, 2 ; Iron, Sub. Carb. Lime, 2 ; Magnesia, 

 0.91; loss, 1. 



The Crassamentum contains the fibrin and coloring mat- 

 ter. Fibrin, known by the names of coagulable lymph and 

 fibre of the blood, is the basis of muscle, and, according to 

 Berzelius, in 100 parts, has Carbon, 53.360; Oxygen, 19.666; 

 Hydrogen, 7.021; Nitrogen, 19.934. The coloring matter 

 contains iron, which is found in the red globules. 



MICROSCOPIC EXAMINATION OF THE BLOOD. 



FIG. 2. Under the microscope, nu- 



merous little red particles, 

 termed globules, or corpus- 

 cula, are observed. 



The form of the globules 

 varies in different animals; 

 in man and all the mammalia 

 it is circular and flattened, 



with a cup-like depression on both surfaces, while in birds, 



reptiles and fishes the form is elliptical. 



FIGURE 2. b represents the blood corpuscle as seen within the focus of the 

 microscope ; a shows it when beyond the focus. Magnified 400 diameters.
