ON INFLUENZA IN AMERICA.

more or less accelerated and the breathing a little increased, 
hut in not a single instance were the symptoms so aggravated 
as in the first case. 
The fifteen remaining horses in the stable now exhibited 
yellowness of the visible mucous membranes, as well as a 
staring coat. They ate as well as usual, and on the evening 
of the same day many of them were coughing. Some of the 
first lot that showed signs of the disease on the 13th partly 
refused their food on the next day, while others ate greedily. 
On the 13th there was not a single horse in the stable of 
thirty-two free from the disease, even to be noticed by the 
groom. Some of them required no treatment at all further 
than some nitrated water being left in the manger, while 
others had to be promptly attended to. 
On the 16th there was scarcely a horse to be seen in the 
streets that did not show signs of the distemper by coughing 
and a discharge from the nostrils. All the livery stables were 
closed and private horses were laid up with the malady. To 
relate the symptoms of each case would be an unnecessary 
task, but I will relate briefly the principal interesting features 
of the disease and such cases as are worthy of special notice. 
The suddenness of the attack alarmed the owners of horses 
very much, and caused them to be much more eager in seek¬ 
ing the services of veterinary surgeons at an earlier period 
than if the disease came on gradually. This circumstance 
enabled me to see a great many cases (over 250) at the out¬ 
set, and without exception there was not a single horse that 
did not exhibit yellowness of the visible mucous membralie. 
I looked upon this symptom, together with some of the fore¬ 
going ones, as diagnostic of epizootic influenza. To return to 
the remarks connected with the outbreak, I may further add 
that the first animal alluded to continued to show indications 
of colic (although a laxative was administered which gently 
moved the bowels) at intervals up to the 18th, but not to an 
alarming extent. The other symptoms did not improve 
after the colic had ceased. There was a free flow of dis¬ 
charge of a muco-purulent character from the nostrils, and 
when he coughed he expectorated a quantity of viscid 
phlegm. 
On the 20th there was a great difficulty in the breathing 
as though the animal was choking, and a gurgling sound 
which seemed to arise from the neighbourhood of the posterior 
nares accompanied it. The discharge, which had run freely 
for four or five days previously, and suddenly stopped on the 
night of the 19th, was supposed to be the cause of the sound 
and also of the laboured breathing. He was now made to
