INTUSSUSCEPTION OF THE BOWEL IN THE OX.

twenty minutes. After that these attacks disappear abruptly 
and entirely as if cured, but after thirty minutes or one hour 
they recur and so continue from six to twelve hours; after 
that the animal lies down quietly, occasionally gets up and lies 
down again. The pulse is accelerated, temperature normal, the 
muzzle is moist, ears and horns are slightly cold, and the ab¬ 
domen is distended with its contents. The peristaltic move¬ 
ments in the bowel are suspended in the early stages. These 
symptoms are very often recognized by veterinarians as simple 
colic or impaction, and treatment is given for same without 
further or closer observation, and for this reason—there are so 
few reports of cases in literature. 
On palpation we detect an intense sensitiveness of this region, 
and die animal shows signs of pain on percussion. We can also 
recognize invagination by rectal examination as far as the float¬ 
ing colon, but when it comes to the small intestine it is some¬ 
what difficult. 
The animal in the course of the disease becomes comatose 
and seldom struggles. The appetite is entirely suspended, but 
during the progress of the disease the animal will drink water 
frequently. The mucous membrane becomes greatly congested 
and the eye gives an expression of anxiety, very often a staring 
look as if the animal was frightened. In the latter stages cold 
chills are observed, the lower limbs become cold, seemingly the 
circulation somewhat tardy. Considering all these symptoms 
veterinarians should not fail in recognizing these conditions, 
although strangulation and invagination resemble each other 
very closely and can hardly be separated except by incision 
through the abdomen. 
Siebert’s treatment for invagination is by attempting to re¬ 
duce invagination, either by operation or generating carbonic 
acid gas in the body. He relies greatly on the latter treatment. 
After giving aloes with sulphate of soda in linseed tea, he in¬ 
jected twenty-five ounces of bicarbonate of soda suspended in 
water into the rectum, which had been previously emptied as 
far as possible with the hand and tobacco clysters. Diluted hy-
