repast, and in the fur countries they follow the

of the birds dissected by Mr Audubonf contained, 
among other remains, those of fish, but these may 
have been derived from the intestines of the sea- 
fowl on which they had been preying, not from 
fish taken by their own exertions. 
The form of the Jer Falcon is very strong and

than that of the Perigrine, and the tarsi are fea- 
thered for an inch and three quarters downwards. 
The length of an adult seems to be from twenty to
