HILL’S BOVINE PATHOLOGY AND SURGERY. 
The publication of Prof. Hill’s new work, “ Bovine Pathology 
and Surgery,” has been somewhat delayed by a difficulty about 
the colored plates which will illustrate the work ; but the difficulty 
has been overcome, and the book will soon be ready. 
Mr. Fleming is actively engaged upon his new work, and be¬ 
tween two and three hundred illustrations are already prepared 
for the text. 
CORRESPONDENCE, 
Hartford, Conn., October 18, 1881. 
Editor A merican Veterinary Review : 
In the last number of the .Review I noticed reports of cases in 
which the trocar and canula were used for relief of tympanitis 
occurring in the horse. 
To the best of my knowledge this operation has been done 
very rarely except by the French. While in England I saw the 
operation done once only, and Williams, in his Surgery, contents 
himself with writing in regard to it that it may be of use in some 
cases, but that it has not been so in his hands in any case. 
In this country it is not, I think, generally regarded as a safe 
operation. 
I have performed the operation once only, and with relief so 
marked and immediate that I must have the evidence of other 
cases before deciding finally that to the operation alone was due 
the very satisfactory result witnessed.
