68 DEPOSITS OF LYMPPI AROUND THE TRACHEA. 
rounded the bronchi and enveloped a portion of the right 
lung, which was consolidated and slightly adhesive to the 
ribs. About three quarts of fluid were found in the right 
pleural sac, but none in the left. The left lung was likewise 
healthy. I regret that I did not determine to forward you 
more of the diseased parts, until the butcher had proceeded 
too far in his operations of cutting them up. 
The subject of this disease was a very fine short-horn cow, 
which had been purchased by a friend and client of mine, 
Mr. Smith, of Risely Grange, at a fair on the oth of 
November, having then two months to lie before calving. 
She was considered to be in perfect health up to the 7th of 
December, on which day it was noticed that she refused both 
food and water. 
I saw her on the following day, when I found the pulse 
full and frequent; the breath sweet, but the respiration 
somewhat difficult; surface of the body warm ; nose moist; 
the bowels slightly relaxed, but an absence of the usual 
symptoms of pleuro-pneumonia. 
I abstracted about two gallons of blood, gave a fever 
draught, and applied a blister to the throat and along the 
course of the trachea. 
On visiting her the next morning, the symptoms were 
such, that both her owner and myself agreed upon the 
propriety of slaughtering her. The rumen was so much 
distended with gas, as to enforce the necessit}^ of this being 
quickly done ; and as such, I did not introduce the trocar, or 
give any medicine to neutralize the gaseous matter. 
I perhaps should tell you, that at the early part of this 
year Mr. Smith had several cases of pleuro-pneumonia. 
Since this time, occasional cases of catarrh and obstinate 
laryngitis have occurred. These have been associated with 
enlargement of the parotid glands, a great difficulty of 
breathing, and much noise in the respiration. They have, 
however, been somewhat successfully treated by blisters, 
setons, 8cc.

[Several specimens analogous to the one forwarded by 
Mr. Dickens have at different times been sent to the College. 
Some of these have been accompanied with the lungs of 
the animal, which, on more than one occasion, have pre¬ 
sented the usual appearances seen in cases of pleuro-pneu¬ 
monia, a fact not without value in determining the cause of 
the effusion into the trachea and bronchial tubes. A further
