THE GROUSE IN HEALTH AND IN DISEASE 



as mothers, and the sort of bantams that would be most suitable would 

 be " Silkies." 



At Mr Pain's ground, where the Grouse were allowed to hatch their own 

 eggs, the results obtained were very remarkable when compared with the 

 results obtained from eggs placed under foster-mothers. 



Hens Nos. 7 and 8 had one cock bird between them. No. 8 would not 

 sit, so her eggs were put under No. 5, and all proved to be fertile, and hatched. 



Out of forty chickens hatched out seventeen have died ; all the rest of the 

 birds are healthy and strong. Those that died were all between four and six 

 weeks old ; these birds were examined by Dr Fantham as well as by myself, 

 and were all found to be sufi'ering from Coccidiosis. Coccidia were chiefly found 

 in the duodenum and blind casca, but many of these young birds also presented 

 symptoms of pneumonia ; in these birds we both found coccidian oocysts in 

 the trachea, the bronchi, and the bronchioles. It is quite possible that these 

 coccidian cysts in the bronchioles would be capable of setting up sufficient 

 irritation to account for the pneumonic symptoms observed in the lungs of 

 such young birds. It would seem therefore that the old name of pneumo- 

 enteritis, which, as applied by Mr Tegetmeier and others to one of the diseases 

 that caused mortality in Grouse, has met with great criticism, may after all 

 be proved to have some foundation in fact.
