Coccidiosis 



Fifteen uncomplicated cases of coccidiosis were found in Flock C and none in 

 the other H>icks. No evidence was found in these studies to indicate that coccid- 

 iosis is in an\ wa\' related to neurolymphomatosis. The hematological studies 

 of the birds affected with coccidiosis are omitted since the\- add nothing of im- 

 portance to the investigation. 



An Attempt to Differentiate Neurolymphnmatosis in Sick Birds 

 from the Range by the Blood Count 



The birds in Table 6, Group 1 were sent to the Diagnostic .Service from Flock 

 D and it was impossible to hold them under observation for any great length 

 of time. This explains why the leucocxtes containing rods and granules were 

 counted together. Also, the neutrophilic leukocxtes were not distinguished
