INFLUENZA IN HORSES. 
Before this occurrence I was not aware of the fact that 
red clover is very injurious to sheep if they are kept on it 
for a long time; but that the food was the cause of this 
disease I have little doubt, for of the eight sheep that were 
not sold, two of them quickly took the disease, while the 
remaining six, being kept on grass-land, continue healthy. 
A few days since I had some conversation on the subject 
with Mr. F. Sowerby, of Aylesbv, a very extensive and 
observant farmer, when he told me that twenty-five years 
ago he put some sheep on red clover, and in one week, in 
the month of July, he lost thirty-five of what was called the 
“ yellows,” and was recommended to sell the remainder. 
This communication has already far exceeded my intended 
limits, but the fearful losses farmers occasionally sustain 
among their sheep, and the importance of a means of pre¬ 
vention, must be my apology. 
INFLUENZA IN HOUSES. 
By J. Bolton Hall, M.R.C.Y.S. and V.S.R.A., Simla. 
Occasionally I get the Veterinarian out here, but 
strange to say, I seldom see in it any communications from 
my professional brethren in this country. Certainly there is 
rarely anything very remarkable occurring, the diseases 
being those incident to a campaign; but from the number 
of horses under the care of veterinary surgeons, something 
might be culled interesting to your numerous readers. 
In this communication, I am about to give merely a rough 
sketchof an epizootic disease that broke out some monthssince, 
and one respecting which, considering its universality, there is, 
perhaps, more difference of opinion as to the most successful 
mode of treatment, than almost any other: I allude to influ¬ 
enza. It is rather an ambiguous term, but possibly it was 
originally given to the disease, not only from the effect it has 
on the animal itself, but on all others associated with him ; for 
it is most certainly and incontrovertibly the case that if one 
horse be attacked, you may expect the malady to affect the 
whole troop. Yet some persons will contend that it is neither 
contagious nor infectious, and they may to some extent be right, 
since, unquestionably, you have the same exciting cause in 
operation which not only brings on the disease in one horse but 
will do so in a thousand. However,it happened in almost every
