account given. He was attended by a practitioner residing in 
that place, and he died on the second day. 
I am very sorry I cannot give the post-mortem examination of 
this case, not having had the opportunity of seeing him either 
before or after death. I did make all the inquiry I could of the 
person who bought the carcass ; but all he could tell me was, 
that he noticed that the heart was considerably larger than any 
he had ever seen before, and that its texture was much softer ; 
and also that in some parts it was blacker, and in others of a 
lighter colour than common. 
I have many other cases recorded in which I have given the 
acid, and with similar success ; but at present I think I have 
stated enough to warrant me in the opinion I expressed in my 
case of phrenitis — that prussic acid has a considerable effect in 
strong spasmodic action of the heart. If administered in small 
and repeated doses, I am convinced that it has a powerful effect 
ori convulsive, spasmodic, and nervous action, generally ; and 
more so than if given in large and overwhelming quantities. 
My first trial of it was on a young greyhound of mine in the 
year 1824. He had recovered from the distemper, but it had 
left him much afflicted with chorea of the head, neck, and one 
fore leg, which resisted all treatment during two months. I 
therefore determined to try prussic acid, and either to kill or 
cure him. I commenced giving him two drops in two ounces of 
warm water twice a-day, with good and nutritious food, and 
was very much surprised to find that, after taking the medicine 
only two days, the affection much abated. In seven days there 
was not the least symptom of the disease remaining — the dog 
grew apace, and made a very excellent one in the field for three 
or four vears.

I have also given it in cases of spasmodic cough, with the 
happiest results ; and of late I have administered it in pneumonia 
with very encouraging success. At present I shall not offer any 
comments on these cases, but will leave them to that tribunal, 
practice, and future experience, to which I trust that I shall 
ever bow.

I perceive in the last Number of The Veterinarian, a 
few remarks on the use of tartarized antimony as a vesicatory on 
the skin of the horse, which is an extract from a letter I sent 
some time since on another subject. This article having ap-
