CASE OF EMBRYOTOMY.

A few hours after this, the pulse became weak, and hardly per¬ 
ceptible ; the inspiration was rapid—the expiration slow. Some 
minutes before the horse died the pulse was yet more feeble, 
and with greater difficulty of distinguishing* the pulsations, while 
the beats of the heart still continued strong and regular. The 
parietes of the abdomen were much distended, and the animal 
fell, and died almost instantly. 
On opening the abdominal cavity, the cellular tissue that 
separates the inferior muscles was found to be infiltrated with a 
yellow serosity; and the intestines were enormously distended 
with air, with patches of black scattered here and there on the 
mucous membrane. The stomach, much distended, offered the 
same infiltration at its smaller curvature. The internal mem¬ 
brane was red, as was that of the colon; the liver was small, 
soft, yellow, and easy to be torn. The diaphragm presented a 
fissure about a foot and a half in extent, at the fleshy and inferior 
part near the sternal region. Between the shoulder and the 
thorax, there was an effusion of blood of a violet colour. The 
tissue of the lungs was very red, as were the lymphatic gangli¬ 
ons situated at the division of the bronchise. The mucous and 
internal membrane of the trachea was also very red. The peri¬ 
cardium contained a large quantity of yellow serosity, such as is 
seen in dropsy. The tissue of the heart w T as softened, its inter¬ 
nal membrane red ; w hile the auricles and the aorta were of a 
yellow tint. Nothing was observed in the other parts. 
In a third experiment the same appearances were observed; 
the diaphragm was found to be equally torn, but this w-as mani¬ 
festly occasioned by a sudden fall. Finally, this experiment, re¬ 
peated on other horses, w r as always attended by the same results ; 
and out of nine, seven had the diaphragm ruptured, at the inferior 
region near the sternum, with an injection of violet-coloured 
blood; distention of the whole capillary system of the frame, 
and, above all, of the subcutaneous and the pulmonary vessels. 
A Case of Embryotomy.

On the 1st of March I was consulted respecting a Breton cow, 
twenty years old, which was unable to calve. I soon discovered 
the obstacle to the delivery. The fore limbs presented them¬ 
selves as usual, but the head and neck were turned backwards, 
and fixed on the left side of the chest, while the foetus lay on its 
right side on the inferior portion of the uterus. I vainly attempted 
placing the mother in different positions during my efforts to
