different wharves of London, but fortunately the disease was 
promptly detected by the inspectors to the Customs, and the 
diseased animals were destroyed. Notwithstanding the visjilance 
which was observed, some sheep, in whose systems the infection 
was incubated, found their way to the metropolitan market, but 
were quickly detected by the breaking out of the eruption prior 
to their being sold and sent into the country. 
The official inquiries which were made proved that the risk of 
the disease gaining foothold here was so great, that the Government 
did not hesitate to issue an Order of Council requiring that all 
imported sheep should cither be placed in quarantine for four- 
teen days, or be slaughtered within three days of being landed. 
This Order proved most effective in preventing the introduction 
of the disease, and thus saved our flocks from being attacked 
with this most malignant and fatal malady. Some new experi- 
ments were had recourse to in the College Infirmary, with the 
fresh supply of small-pox virus, to determine, among other patho- 
logical problems, whether the temperature of an infected sheep 
would rise early in the latent or incubative stage of the disease, 
as it is known to do when the system has received the morbific 
matter of cattle plague. 
In every instance the temperature rose from 102° to 105° 
Fahr., thus affording a good practical test of determining the 
incubation, or otherwise, of the infectious matter in the organiza- 
tion of sheep exposed to small-pox. 
In a former report attention was directed to the rapid spread 
of parasitic diseases among domesticated animals, and the 
serious losses the owners of stock were sustaining therefrom. 
These losses have not been materially diminished as yet, nor can 
we hope for much benefit until science is enabled to throw 
additional light on the mysteries which surround the deve- 
lopment of parasites in general, and of entozoa in particular. 
From time to time, as opportunity offers, inquiries of this kind 
will be prosecuted. During the year, young sheep suffered to 
a serious extent from JilarioB in the wind-pipe, and also from 
another variety of entozoic worms which locate themselves in 
the stomach. 
Numerous cases of hydatids in the brain of sheep have also 
been received at the College, and further experiments are being 
carried out in this direction, although it may be said that the 
natural history of the brain hydatid is pretty well understood. 
Special advice has been given to several persons who sought 
assistance in consequence of the existence of disease in their 
flocks from the brain hydatid, and it is believed that benefit has 
resulted in not a few instances. 
The disease known as " rot" prevailed in some districts,
