REPORTS ON THE INFLUENZA 
may be inferred, that the disease in this case, as in others, 
commenced in the membrane of the nose. 
Treatment . — This would preliminarily consist in the removal of 
the diseased sheep from the healthy, and keeping them separate, 
and in the earliest possible detection of the disease itself. To 
effect which objects it is indispensable that the flocks should be 
examined two or three times a- day, or, what would be better, 
every four or six hours, as the success in preventing the spread 
of the disease, as well as in the case of the affected animals, is 
entirely dependent on the promptitude with which these primary 
observances are adopted. 
The remedies themselves consist of bleeding and aperients, 
and the earlier these are had recourse to, the infinitely greater 
the chance of success ; but they may be used up to or even 
during the second stage of the disease with some possibility of 
advantage. 
In the third stage, no attempts at either relief or cure have 
been found of any avail. In the first instance, extract about a 
pint and a half of blood from the jugular vein, and as soon as 
possible give one ounce of Epsom salts and a drachm of nitre in 
a pint of warm gruel, and repeat the bleeding, if requisite, to 
the same extent, in four or six hours. 
Observations . — The want of success from bleeding seems, in 
those instances in which it has been observed, to have arisen 
from two obvious causes: 1st, The abstraction of too small a 
quantity of blood to be of any avail, instead of the copious 
abstraction, and the repetition of the same, if required, as above- 
mentioned ; and again, on a most destructive plan of employing 
bleeding as a preventive of the disease, and thereby reducing the 
strength of the animals, and rendering them not only more liable 
to be affected with the disease itself, but also less able to sup- 
port its ravages, and still less so to sustain the means necessary 
r its cure. 
During the progress of the disease the bowels are sometimes, 
though not generally, constipated ; and in a very few cases there 
is a frequent desire to void urine ; but this symptom did not 
appear in any vray dependent on the disease, and was, perhaps, 
not more frequent than under the ordinary circumstances of the 
animal. 
The powers of ruminating and swallowing are unimpaired, 
and the animals are not only able to stand, but walk throughout 
the disease. 
The duration of the first stage extends from six to ten hours ; 
the second stage is nearly of the same continuance ; the last 
stage is more brief, and the average duration of the disease
