ANNUAL REPORT FOR 1893 FROM THE 
PRINCIPAL OF THE ROYAL VETERINARY 
COLLEGE 
In Reference to the Investigation of Diseases of the Animals 
of the Farm. 
The following Report of the Professor of Comparative Pathology, 
a department which was founded a few years ago by the aid of a 
grant from the Royal Agricultural Society, must be taken only as 
a selection from the subjects which have been under investigation, 
and not as representing the whole of the work of the past year. 
Considering the short time which has elapsed since the department, 
with a fully equipped laboratory of research, was established, there 
is every reason to be gratified at the results which have been 
obtained. N ot only are new members of the veterinary profession 
sent forth with a practical familiarity with modern methods of in- 
vestigation, but established veterinary surgeons avail themselves in 
a steadily increasing ratio of the resources which the College is now 
enabled to offer in answer to their inquiries, and it is impossible 
that these facilities can fail to raise the scientific status of the 
veterinary profession throughout the country. In the present 
report the diseases which are dealt with are : — 
Anthrax, especially in regard to its causes and indications. 
Tuberculosis, with some important remarks on the use of 
tuberculin as a means of diagnosis. 
Actinomycosis, which is a widely prevalent disease, to be relieved, 
if not radically cured, by the internal use of iodide of potassium. 
Detection of glanders by the injection of mallein, a pre- 
paration from the virus of the disease. 
A fatal disorder of horses which has long been known, but 
only exhaustively studied recently. 
A new disease among turkeys causing serious fatality among 
them. The investigation proves that the malady depends on an 
organism, and that the disease is readily conveyed by inoculation to 
turkeys, but with difficulty to fowls. 
Several parasitic diseases are considered, and among them a 
form of inflammation of the intestines in cattle, due to the presence 
of an extremely minute worm, which is not visible to the unaided
