EXTRACTS FROM EXCHANGES. 
the author having failed to obtain a constant reduction by the 
ordinary manipulations, taxis, pads, or sutures of the anus, 
had recourse to the application of the metallic ring which is 
employed for the contention of the uterus in a cow with some 
modification. Instead of giving it the form of a triangle, he 
merely flattened the ring sideways to give it an oval shape, 
and slightly bent it to adapt it to the hollow of the anus. 
This ring, well padded with oakum, is applied in the anal 
hollow after reduction of the prolapsus, and kept in place 
with four elastic strings or bands to the collar of the animal, 
to which a stiff collar of pasteboard is put on to prevent its 
biting. The recovery was complete. 
In a subsequent article, Prof. Degive recalls another form 
of treatment, which consists in passing round the anus, at some 
little distance from its border, a string which is carrfed round 
the organ in and out of the skin, and brought back at a point 
near its starting insertion. By traction upon both ends of 
the string, the skin of the anus is drawn close at will and se¬ 
cured by a knot, similar to the string on a tobacco bag or a 
purse, and still the exploration with the finger or the passage 
of faeces softened by rectal injection can take place.— Ibid. 
AMPUTATION OF THE UTERUS IN THE SOW. 
By M. Adriaen. 
The author reports two cases of this operation which dif¬ 
fer somewhat in the manipulations applied, and were followed 
by different results. In the first animal the amputation was done 
by the application of a strong elastic band and amputation of 
the protruding uterus. There was but little hemorrhage, 
the uterine stump soon withdrew in the vaginal cavity and 
the animal did not seem the worse by the operation, except 
that her milk gave out and her litter soon died from starva¬ 
tion. Ten days later the sow was taken with severe pains, 
with violent efforts as if severely constipated, and though she 
received a cathartic, these becoming more and more serious* 
she was killed. At the post-mortem a large tumor was found 
at the bottom of the vagina, containing a small quantity of
