Mrs. Miller, 27, Belgrave Road, S.W. Answered by post. 



Colour-fed Hen Canary (Frank Howe, Wellingborough). 

 Death was due to acute septic fever. Probably you will 

 lose some more. At present the mortality from this disease 

 is very great. In my own case I have lost one batch of 

 60 expensive birds which showed the disease in the form of 

 small yellowish foci in the liver and spleen, the latter organ 

 being completely disorganised. In these foci almost pure 

 sultures of a small bacillus were found. It is a very 

 contagious disease and has spread to all classes of birds 

 (British and foreign) insectivorous, frugivorous, and semi- 

 nivorous. Egg-food has played no part in it. It was in- 

 troduced by foreign insectivorous birds. The period of 

 incubation is doubtful. Although the disease must have 

 been in existence in the bird's sj'stem for some time judging 

 by the post mortem lesions, very few or no symptoms were 

 observed until the day before or on the day of death. 



Lavender Finch (Mrs. Mellor, Fairlawn, Lytham, Lanes.) 

 Cause of death, enteritis, due to climatic changes and pro- 

 bably latent infection. See remarks on Avian Cholera in 

 Sept. issue. These birds are very fond of the ordinary 

 insect food, and should have it always by them. 



Hen Plumed Mountain Quail (F. C. Thorpe, Havenside, 

 Hull). Cause of death, infectious enteritis. 



Hen Parrot Finch (M. C. Hawke, Wighill Park, Tadcaster). 

 Cause of death, pneumonia. The bird had not finished its 

 moult, and this, together with incubating eggs acted as a 

 great predisposing factor in the causation of its malady.
