CASK OF ANEURISM.

she was a good subject for experiment, and he gave her up to 
me for that purpose. From the known effect of mercury upon 
the absorbent system, I determined to administer it with nar¬ 
cotics. 
Treatment .—Give every night the following powder: calomel 
two scruples, extract of hemlock a drachm, and powdered opium 
half a drachm, with liquorice powder; and on every morning, 
until purging was produced, four ounces of Epsom salts in eight 
ounces of* the infusion of cascarilla, with the same quantity of the 
infusion of roses. As soon as purging commenced, I omitted 
the internal medicine, shaved the hair from the off side, and well 
rubbed in an ouilce of strong mercurial ointment, with a drachm 
of camphor; and the rubbing was repeated daily for six days. 
During this treatment she lost flesh, and became so weak as not 
to be able to raise herself up when down; and, in consequence of 
the tumour not diminishing, I had her destroyed. 
Post-mortem examination .—On opening the abdomen, the first 
thing which presented itself was a large mesenteric gland, of a 
tabulated form, weighing 1601b. On making a section through 
this immense substance, its appearance was chiefly a schirrous 
deposit, and in some parts it contained an unhealthy-looking pus: 
a small part of it had the appearance of crassamentum, sur¬ 
rounded by a thickened portion of mysentery. It was situated in 
the iliac region, which it completely filled, except that portion of 
the cavity which was occupied by the rectum. There were 
attachments to the spine by the mesentery, and to the psoas par¬ 
vus on the off* side by dense cellular membrane. The intestines 
were attached to the anterior surface in their usual convolutionary 
way; the posterior portion of the caecum adhered to the inferior 
surface of the tumour, and the part so adhering was obliterated ; 
the rectum passed over the superior surface on the near side of 
the spine. The mesenteric glands presented throughout 5. gene¬ 
ral unhealthy appearance; and a great number of them were 
schirrous. 
CASE III. 
On the 29th of May 1829, I was requested to attend an aged 
mare, which had foaled about 4 a.m. I was from home at the 
time, and the message left was, that the mare was very ill, and 
they supposed that she had some obstruction in her urinary pas¬ 
sage. On my arrival at 7 p.m. I was informed that the mare 
was dead; and the gentleman accused me of having lost his 
mare in consequence of my negligence. I remonstrated with him 
on the improbability of the mare’s death having been caused by 
strangury in so short a period; at the same time stating, that
