 leucocytes, fat globules and coccidia. 



The gregarinse are not confined to the caeca but scattered over 

 the whole intestinal canal as white spots in the submucosa sur-

Symptoms. Dullness, anorexia, ruffled feathers, sunken head, 

 trailing wings, slow uncertain gait, plaintive cries, with diarrhoea,
