fresh preparations of the blood, portions of red cells may be 

 seen within the granular leucocytes. The determination of the 

 extent of this mode of destruction of the red corpuscles neces- 

 sitates further investigation.

In fresh preparations of 

 the blood of affected fowls 

 examined in Toisson's fluid, 

 red corpuscles which take 

 the violet stain more or less 

 intensely throughout are 

 frequently observed. 



In the blood of poultry 

 two distinct classes of white 

 corpuscles are conspicuous. 

 The first which predomin- 

 ates in numbers, contains 

 from one to four nuclei, and 

 the cytoplasm is sprinkled 

 with a variable number of 

 round, elongated, or spin- 

 dle-shaped bodies. In the 

 fresh condition they are
