THE INFLUENZA OF 1836.

down. Both died. The “pleura was much diseased; in one the 
bronchi were gangrenous ; in the other, which lingered for a 
good while, the bronchi were nearly or quite sound ; but a por- 
tion of the lungs was solid, apparently from obliteration of the 
air-tubes. Except from relapse or neglect, there has been no case 
of influenza in combination with pleuritis and hydrothorax. 
Diabetes has occurred in several cases, always at the decline of 
the disease. It required treatment in, I think, only three. 
Hepatitis has not been seen by me : I have heard of it from 
others, but I do not believe that the engorgement and tenderness 
of the liver have any connexion with inflammation in its sub- 
stance. Cellular effusion has been very rare. In a few cases the 
legs, sheath, and brisket, have swelled, but in a much less degree 
than usual after a sharp attack of pneumonia or influenza as it 
prevails in spring and autumn. I do not understand these se- 
rous effusions ; but I am disposed to believe that hydrothorax, 
ascites, cellular effusion, and perhaps diabetes all arise from a 
particular state of the system, more than of the organ by which 
the fluid is furnished. This, however, is merely conjecture. 
Glanders and farcy , in a very acute form, have been connected 
with influenza; but you, Mr. Editor, and your readers, will easily 
understand why I am silent regarding them. 
The fatality of the disease has not been very great, considering 
the number of cases. In my own practice I have lost only eight. 
I do not know how many have come under treatment; I have 
no list, and cannot remember more than between 150 and 160. 
But between neglect and the bad treatment of quackery, the 
deaths have been sufficiently numerous ; so many have died, 
that, notwithstanding the high price of provender, all kinds of 
horses are dearer than usual. 
Auscultation might be of much service to us in this disease : 
it ought to be studied in veterinary medicine. I have long 
been in the habit of sounding the chest ; but my progress has 
been so small, that I cannot venture to make any remarks about 
it. I cannot describe the sounds, and some of them with which 
I am familiar seem to exist in different states of the lungs; 
and in health the respiratory murmur is not the same in every 
horse. In thoracic influenza, both sides of the chest never give 
the same sound : one side, or one portion of a side, will be dumb, 
another loud, and another perhaps roaring, growling, or grum- 
bling ; often there is a gurgling sort of sound. The alteration 
is always most distinct at the lower part of the chest. By the 
extent more than by the kind of alteration, I am often guided 
as to the propriety of applying blisters to the sides. 
Before concluding, I would suggest the propriety of discussin
