In making the differential counts we have used a classification of the 
leucocytes similar to the one proposed by Giltner. 1 Drake 3 recognizes 
only three varieties of leucocytes, but we agree with Giltner in that five 
varieties can be easily distinguished in a well-made and well-stained 
spread. Dinwiddie 3 also recognizes five classes. He classifies all the 
mononuclear elements under one head, and gives the transitional forms a 
special classification. 
The following is a somewhat detailed description of the various classes 
observed in our studies. 
Lymphocytes. —Burnett 4 states that the cells falling ir this group 
have practically the same appearance in the majority of domesticated 
animals. With Wright’s stain the cell body has a greenish blue tint, 
while the nucleus has a dark-violet tint. Giltner 1 describes two kinds
