Leucocytes, 64,700 per cu. m. m. 



Large lymphocytes, 2.8'/, , or 1,812 per cu. m. m. 



Small lymphocytes. 88.6 ( / c , or 57,42-1 per cu. m. m. The 

 lymphocytes are much smaller than those found in human 

 blood, and they stain very feebly. 



Xeutrophiles, none found. 



Eosinophiles, 5.8%, or 3,763 per cu. m. m. 



Basophiles, 2.5%, or 1,618 per cu. m. m. 



Amphophiles, 3%, or 254 per cu. m. m. 



The eosinophiles and basophiles resemble those of human 

 blood. 



Serum, isotonic with human serum. 



Adult female toad. 



Hemoglobin, 63%. 



Erythrocytes, 526,000 per cu. m. m. The erythrocytes are 

 oval and mostly nucleated, very irregular both in form 

 and size. A few non-nucleated cells are seen. 



Leucocytes, 27,800 per cu. m. m. 



Large lymphocytes, 1%, or 278 per cu. m. m. These re- 

 semble the lymphocytes of medium size sometimes found in 

 normal human blood. 



Small lymphocytes, oval, rather deeply staining, 46.6%, 

 or 17,058 per cu. m. m. 



Small lymphocytes, round, feebly stained, 33.8' 7 , or 9,396 

 per cu. m. m. 



Mononuclear neutrophiles, 2' , . or 556 per cu. in. m. These 

 stain very feebly, nuclei often eccentric. 



Polymorphonuclear neutrophiles, 9.2',. or 2,758 per cu. 

 m. m. These stain very feebly, nuclei extremely irregular in 

 form. 



Eosinophiles, 1.6%, or 445 per cu. m. m. Stain very 

 feebly. Granules irregular in size, often very large. 



Basophiles, 5.8%, or 1,612 per cu. m. m. These stain with 

 remarkable brilliancy, the granules are like those of human 

 basophiles. They are usually mononuclear. 



Serum, isotonic with human serum. 



Adult goldfish. 



Hemoglobin, 50%. 



Erythrocytes, 935,000 per cu. m. m. Erythrocytes vary 

 from oval to almost round, nucleated, each erythrocyte carry- 

 ing nearly 27-100 as much hemoglobin as the human erythro- 

 cyte. A very few non-nucleated cells are found. 



Leucocytes. 44,400 per cu. m. m. 



Large lymphocytes. 3.2%, or 1,421 per cu. m. m. 



Small lymphocytes, 62 r , . or 27,528 per cu. m. m. The 

 lymphocytes vary greatly in their staining reactions. 



Xeutrophiles. 30%, or 13,320 per en. m. m. These cells
