 none 



Fresh culture (Metamorphosis doubtful.) 



Culture, twenty-three days old. Bird looks fit. 



Shows unfertilised ova in droppings — first time. There is 



a very slight infection with coccidia in this bird. 

 Culture, thirty days old. 

 Died, and was examined by Dr Leiper. 



"Tissues preserved. Also complete lung showing discoloration that may 

 be 'pneumonic,' but the ciBca were intensely injected with a good deal of 

 blood in cpecal contents. Rectum full of chalky fluid. The intestines seemed 

 normal. Spleen was enlarged, this I also pickled." — R. T. L. 



" I had a look over sections of the lung and found some of the culture 

 in the bronchioles. The cfecal condition remains the same, even though we 

 ultimately decided that death was due to the culture in the lung." 



" Trichostrongylus in this case required at least seventeen days outside 

 the body, a very much longer time to arrive at the stage of development 

 necessary for infection than analogy would lead one to expect." — R. T. L. 



" I notice that in the warm weather complete metamorphosis is accom- 

 plished in eight days." — R. T. L.
