j>earance, and not dissimilar to the same organ in the human 
subject: the ductus communis choledochus is veiy tortuous, and can 
be seen tenninating in the duodenum. The spleen is long and 
narrow, and there are no supra-renal glands attached to the kid¬ 
neys ; the renal veins ramify on the surface in most animals of 
this class; these organs are not enveloped in peritoneum, but 
possess a proper tunica propriay and exhibit a beautiful appear¬ 
ance. . Another peculiarity, and with which I shall conclude the 
present communication, is that of the aorta, and which is a re¬ 
markable deviation from the human subject. The arch arising from 
the aorta, instead of being transverse is conical, and only gives 
off two arteries instead of three, as in the human subject. The 
same fact is to be noticed in the dog and rabbit. The largest, or what 
I call the arteria innominata, trifurcates, giving off the right sub¬ 
clavian and two carotid arteries, while the left subclavian arises 
sepamtely. With the exception of the part where I have quoted Dr. 
Fyffe, the above are observations from my own dissections ; and 
I shall be happy to assist any gentlemen in making comparative 
dissections, more especially exotic animals; and for the loan or pre¬ 
sentation of any specimens, T shall feel much obliged.

CASE OF DISEASED RECTUM. 
By Mr. D ANiEL Moulden, Winchester. 
IT is with pleasure I avail myself of the opportunity which now 
offers, through the medium of your useful publication, ^^The 
Veterinarian,’’of submitting for the perusal of the profession the 
subjoined case of diseased rectum. 
On the 15th of June, 1819, I was applied to by James Gold¬ 
smith, Esq., of Milton, near Portsmouth, to examine a black 
horse, that had been ill for eight months; voiding his faeces with 
difficulty, and in an oblique direction. I passed my hand up 
the rectum, and found a large tumefaction, about eight inches 
long, three inches in thicfaiess, and nearly six in width. 
I ordered him to be sent to my stable, and on my arrival desired' 
my servant to foment the part for an hour. I passed both 
index fingers within the verge of the anus, and could see plainly 
the nature of the tumour, and the sinuses, which discharged, very 
copiously, thick healthy pus. I injected a solution of sulphate of 
zinci cum hyosciami ext. This application was had recourse to 
twice only. I gave him at night hyd. sub. 3ij, cum sapon, dur.;
