the head resting on the thoracic walls towards the umbilicus. 
By exploration the position was readily made out ; the forelegs 
were engaged in the straight. Notwithstanding repeated at¬ 
tempts it was impossible to return the head to its normal posi¬ 
tion ; and it was not possible to pass a rope around the neck or 
on any part of the neck. Forced extraction with the windlass 
of a truck was decided upon, after tying the fore legs to it. The 
operation was perfectly successful and a well-formed dead calf 
extracted. The cow had no bad results from the operation. 
This animal had already had several calves and her passages 
were quite large. Perhaps these are the reasons that the opera¬ 
tion was successful, contrary to the generality.— [Rec. de Med.

Uterine Laceration at the Time of Delivery as a 
Consequence of Torsion [By A. Lucet \.—The author, who 
is a close observer, considering the subject of laceration of the 
uterus, calls some spontaneous, indicating that they take place 
independently of any interference from the accoucher and only 
by the powerful contractions of the muscular coat of the uterus. 
He relates three cases in relation to this question. W ith the 
exception of one, where manipulations, made previous to the 
diagnosis, might make the case doubtful, the two others are 
positive. The lesion undoubtedly took place before Mr. 
Lucetwas called and no manipulations of any kind haying been 
made before its arrival. In the three cases the examination of 
the uterus revealed a transversal laceration of the muscular coat, 
situated on the inferior face of the uterus. The three calves 
were delivered alive after reduction of the torsion ; the cows 
went to the butcher.— [Rec. de Med. Vet.)

Since equitation is a subject of the army veterinary exami¬ 
nation, the applicants for this examination will do well to 
acquaint themselves with its principles. There are a number 
of such books published in English and other languages, but 
none of recent date. The above treatise is the work of an 
American cavalry officer of experience and high standing. It 
is thoroughly American in its character, upholding the methods 
in vogue in our cavalry ; it is practical, unprejudiced and de-
