Culture of twenty-three and twenty-six days mixed. Looks 



weak and moping. 

 Culture of thirty days. 

 Same culture — now thirty-six days. Some worms active 



— most quiescent. 

 Same culture — now forty-four days. 

 Chick looks very sickly. 

 Chick died and was examined. Its skull was broken — clot 



over brain. Probably pecked and killed. 



Proximal end of each ciscura, about half the length, was abnormally 

 translucent, pale, and fatty in appearance, with injected vessels. No redness 

 of mucosa within any part of gut, but very abundant Trichostrongylus and 

 ova. No coccidia in caecum ; a few only in duodenum. 



Grouse {e), Chick.
