 by post. 



J. N. WllvSON. — Tlie cause of death of young Rosella was 

 septic fever, bronght about by infection on the one hand 

 and exposure to changeable weather on the other. No 

 doubt in your particular case there is an inherent predis- 

 position in the young birds. Septic fever is not the same 

 disease as bird plague, wliich is veiy highly contagious and 

 due to an i!ivisil)le and filtrable microbe. Tliese two 

 diseases are confounded with one another. 



O. MirxSUM— Olive 'l'auai;er. Cau.se of dealli : Inflammation 

 of lungs due to climatic changes. 



Mrs Mei.LOR— Green Ihidgerigar (hen). Cause of dealli : 

 Inflammation of lungs and bowels, probably bronght 

 about by chill acting on the system when dej>ressed by 

 fretting. 



Note. — During the last two years a great tiumher of 

 birds have died, and their deaths could only be attril)ute<l 

 to climatic changes as extraneous infection was out of the 

 question, biids having died in aviaries into which no fresh 

 birds had been introduced for months. 



T. Wilson. — Pennant Parrakeet, in full colour, aged two 



years. In my opinion this bird died from infection 



obtained from the soil of the aviary, the disease being 



brought into activit\- partly by the inonlt and partly by 



the changeable weather. The bird, which was a cock, 



was somewhat emaciated, evidenced by sharpness of the 



breast bone, and had evidently been ill some days. (See 



"Notes on Avian Cholera," page i8i).
