white.

 2. A cell in bone marrow, of a type that is believed to 

 become developed into a red blood corpuscle.

Leukocyte (lu'-ko-sit) \1evk6q, white; i&TOQ, cell]. 

 The colorless or white corpuscle of the blood. Leuko- 

 cytes have ameboid movement and are formed in the 

 lymphadenoid tissue of the spleen, lymphatic glands,

 protoplasm. 3. Transitional forms — cells with a single 

 indented nucleus. 4. Multinuclear cells, with neutro- 

 phile granules — cells having a polymorphous nucleus or 

 nuclei. These constitute 70 percent, of the en- 

 tire number of white blood corpuscles. >. Eosinophile 

 cells. In leukemia another cell, the mvclocy/c, makes its 

 appearance. This is a large uninuclear cell, with neu- 

 trophile granules. 1 ..".wit recognizes two classes, 

 leul and erythroblasts, the latter the anteced- 



ent- ol the red corpuscles. Most authorities reject 

 this division, however. L., Alpha, and L., Beta,
