EXTRA-UTERINE GESTATION. 
This gave no relief, and, therefore, some hours afterwards, 
we administered : — 
01. Lini, §ss ; 
Aloes Sol., ^ss; 
Hydr. Submu., gr. ij. M. 
The second day the animal continued much the same : 
we therefore repeated the fomentations, and gave another 
half ounce of tincture of opium. 
The third day the bowels were acted upon being 
the first time for seven days ; but the pain of the 
abdomen and other symptoms were not lessened as a 
consequence. I expressed an opinion to Mr. Bow r man, that 
if the sow was with any foundation believed to be in pig, as 
she had evidently gone over her time, and there were 
symptoms of something acting as a foreign agent in the 
peritoneal cavity, that it must be a case where the foetuses had 
by accident escaped from the uterus ; or, otherwise, that it 
was a bona fide case of extra-uterine congestion. Under 
such circumstances, we thought it advisable to discontinue 
medical treatment, there being no hope of recovery. On the 
following day she died. 
Post-mortem examination . — Anxious to ascertain the ac- 
curacy of our diagnosis, we proceeded to the tan-yard where 
the sow was opened. The respiratory organs were found to be 
healthy. In the abdomen, however, there wasintense and pretty 
general peritonitis, the visceral portions of the serous mem- 
branes being most affected. The uterus was found to have 
been seriously mutilated, evidently by the imperfect per- 
formance of the operation of spaying. The right horn and 
its ovary, with a part of the body of the uterus and vagina, 
were absent. A mass about the size of a man’s head, 
enveloped in false membranes, was situated in the left iliac 
region, and connected with the left horn of the uterus, which 
was still continuous with its ovary and the vagina. 
On dissecting the tumour, the osseous remains of seven 
pigs were discovered, enclosed in separate cavities. Seven 
heads and all the bones were collected. They were, however, 
denuded of all soft parts, as if they had been subjected to 
maceration. 
This case has many interesting and novel features about it. 
If the vagina had an opening into the abdomen, or if such an 
opening existed only in the left horn, where were the ova 
fecundated ? This act must have occurred as the Graaffian 
vesicles poured forth their contents, so that the semen found
