"The caeca were thin and contained very moderate amount of faeces. I 

 should say they were partially empty. No sign of mucus or other accumula- 

 tion. The walls were very thin and there were numerous Trichostrongylus 

 pergracilis. The contents showed large numbers of eggs. The mucosa of 

 the caeca did not show any petechial spots or appear to be congested, but 

 this may have passed off. The mesenteric veins were not dilated. Lungs 

 showed post-mortem staining." R. T. L. 



GROUSE (O), ADULT <?, ONE YEAR OLD. 



The bird, now two years old, is small, but looks well, and in good feather. 

 Has mated with two hens this season, both now laying. 



This young cock has proved himself to be extraordinarily resistant to 

 infection, compared with the young hen (.6), which died in less than 

 twelve weeks, after six doses of culture. This bird is still quite healthy, though 

 dosed nine times with similar cultures, and kept on the same ground all the 

 while for auto-infection.
