POISONING BY CORROSIVE SUBLIMATE.

of lymph. The lymph deposit was tolerably firm round the 
pin, and strongly adherent in most parts to the heart. The 
muscular structure of the heart was pale, and the general 
form of the organ so altered in appearance, from pressure, 
I imagine, that no form at all like the auricles could be found. 
The pin had entered nearer to the base than the apex of the 
heart, and traces of something like matter, only rather 
tougher and more skin-like, could be scraped off the lining 
membrane of the ventricle, also the chordae tendineae, and 
even some portion of the valves. The channel the pin lay 
in was lined with a similar material. The lungs were 
found to be healthy, except an old adhesion on the left side, 
which had become elongated in the form of a band. 
I regret being unable to give a clearer account of the heart's 
action at the onset of the animal’s illness, for having well 
examined the viscera of the chest, and finding the heart appa¬ 
rently quiet, and a weak pulse existing at the time, I thought 
if the stomach recovered its healthy action the cow might 
soon be as well as usual. The tightness of the skin indicated 
a long-standing disease, but it is not unusual to meet with 
an unthrifty looking patient, one which you are certain ails 
something more than a fresh cold, or a disordered stomach, to 
which you may be administering, which, after being relieved, 
the old complaint will continue on for a length of time. In 
concluding this case, I may remark that the cow calved last 
July, her third calf, a small and bad one, and it still remains 
so. Since then she had not returned to the bull. 
[The pin sent by Mr. Hudson may be rightly described 
as a shawl pin. It is large, and two inches and three 
quarters long. It is slightly bent, and from its point, 
for about two thirds of its length, it is black in colour, this 
being the part which was located in the wall, &c., of the 
heart.] 
POISONING OF A SOW BY CORROSIVE 
SUBLIMATE. 
By C. Hirst, M.R.C.V.S., Barnet. 
I was requested this morning, October 4th, 1801, to make 
a post-mortem examination of a valuable sow, of the Berk¬ 
shire breed, belonging to C. A. Hanbury, Esq., of Belmont, 
East Barnet, which was found dead by the bailiff. The sow,
