EXTRACTS FROM FOREIGN JOURNALS.

is not alwa) T s easy, and the membranes often escape the punc¬ 
ture by the finger. In this case, one must watch for a violent 
expulsive effort of the animal, which, by the pressure it pro¬ 
duces, increases their resisting power and permits them to be 
more readily lacerated. The foetus is, at that time, soon 
pushed back, in such a way that any part of it can be taken 
hold of, as, for example, a foot, and drawn back through the 
os. Reduced in size by the escape of its contents, the uterus 
can no longer maintain the motion of torsion. On the con¬ 
trary, the twist diminishes to such an extent that the head 
and the other leg are easily secured. At that moment it is 
important to rai'se the hinder parts of the animal, and to in¬ 
crease the spiral formed by the uterine mass by a powerful 
extension of the arm which holds the foetus. The animal, 
being on her back while she is down, is then turned slowly 
from left to right, and from right to left, until a favorable 
position is obtained to extract the foetus. 
The lacerations which may take place heal readily by the 
use of creolin. 
Goring adds that “it is useless to speak of embryotomy, 
which plays a greater part in theory than in practice.” 
The author states that he has not performed embryotomy 
for years, but advises beginners to practise it rather than to 
use their strength in vain efforts. Embryotomy is an excel¬ 
lent exercise, and develops the manual dexterity of young 
veterinarians, but the practitioner who knows how to take 
advantage of the dimensions of a pelvis will think but litile 
of it.— Ibid.

TRAITE DE ZOOTECHNIE GENER ALE.—(Treatise of General Zootechny.) 
By Pror.. Ch. Cornkvin. Paris. J. B. Balliere & Son. 
Some years ago, during one of our trips to Europe, while 
visiting our beloved master, H. Bouley, and referring to our 
own humble efforts in behalf of our profession in the United 
States, he said to us: “You commit a great error if you fail 
to teach zootechny in your American schools. Zootechny 
progresses rapidly, and the day will soon come when the edu-
