102 TIIE TUMOURS CONNECTED WITH STRANGLES. 
surface of the body; I stated, or meant to state, that an abscess, 
in the course of strangles, might form in almost any part of the 
body, especially towards the surface : and I am in the habit of 
going on to detail the various situations in which I have met 
with abscesses in this disease. One case especially, which was 
dissected by Mr. Cheetham, who is now in London, and while 
my assistant, occurred in a horse belonging to Mr. Nimmo, of 
Gogar, which had a tumour in the mesentery fully as large as that 
above described, and which I then referred to. I regret extremely 
to have occasion to mention this after the death of my friend Mr. 
Castley, and would rather have allowed it to pass, had not the 
present occasion occurred. At the time his letter was written I 
intended to have noticed it, but expected that I might have had 
the opportunity of doing so in communicating with him on subjects 
which might have been of more importance ; but in this, alas ! I 
was too grievously disappointed. 
I may just mention that I was a few days ago informed by a 
gentleman residing near Cupar, Fife, that a horse of his had 
died a few days before, about which I was consulted some 
time previously, and in which was found, as I had prognosticated, 
disease to a great extent of the mesenteric glands, the sequel 
of strangles. I may also add, that this summer I found in 
a case in which I was under the necessity of performing tracheo¬ 
tomy (and which for two weeks was the means of saving the 
colt’s life, by obviating the effects of the tumour in the neigh¬ 
bourhood of the larynx) an abscess in the anterior portion of the 
mediastinum dorsale, which proved fatal after the other parts 
had almost entirely recovered. I may observe, that there is 
reason to believe that the lymphatic vessels and glands are often 
principally concerned in the origin of the disease. It was not 
surprising that Mr. Castley mistook me, as he dwelt at length on 
the cases which occurred near the surface of the body.
