35 for 1920. They occurred as follows: Columbae 11, 
Anseres 4; Alectorides, 3; Galli, 2; Herodiones, 1; 
Striges, 1; Struthiones, 1; Fulicarise, 1. The distri- 
bution in the garden is significant in only one respect. 
It would seem that we had a group of infected cranes 
in the enclosure near the North gate. Since turning 
over the soil with lime the deaths have stopped, the in- 
fected animals having been removed by death. In the 
large bird house the incidence in the cages is very satis- 
factory. Thirteen cages, infected in 1920 and 1921 have 
failed to show any tuberculous cases. Three oniy were 
infected this year and last year. Three new cages were 
found represented this year. These figures show a 
steady improvement of the hygiene of the bird house 
so far as tuberculosis is concerned. 
Mould disease is decidedly better this year but as 
the fungi are ever with us it may recur; at all events 
we are thankful for any low figures. 
Fowl Typhoid in the Parrots. 
This infectious condition cost the life of twenty-one 
birds during May and June. The origin of it is not 
clear although it was possibly introduced by a new 
comer, additions to this collection being frequent. The 
outbreak is worthy of brief recital for two reasons — 
the measures used to eradicate it and the nature of the 
pathology. During the eight days following May the 
fourth six birds came to autopsy with severe toxic and 
hemorrhagic enteritis, suggesting fowl cholera; one of 
these birds had also pneumonia. From the thirteenth 
of the month until June 9th, when the infection ceased, 
fifteen more birds died but the manifestations were not 
exactly the same, they being divisible into two groups. 
One and the more numerous, amounting to ten, showed 
the intestinal lesions to be a little less serious but with 
the liver deeply, the lungs moderately involved. From 
several of these birds' heart-blood B. psittacosis was 
isolated. The remaining five birds had moderate in-
