REPORTS OF CASES. 
manipulations which the cow had been subjected to by inex¬ 
perienced hands. Consequently a diagnosis was very difficult, 
and proved for several hours to be very puzzling. 
I found the three hind extremities attached to a body of 
large size and shape, such as could not be delivered intact 
through the natural channel. 
I decided to try embryotomy, and succeeded in removing 
the three extremities that were presenting themselves; then I 
found myself stuck; could not find any more posterior extremi¬ 
ties, but could feel a hoof of what I supposed to be a fore 
extremity. 
The pecular formation of the pelvis, together with the 
swoolen condition of the uterus, made it impossible for me, 
with the instruments at hand, to proceed any further with the 
operation. 
As the owner was willing to resort to anything that had 
a chance of saving the cow’s life, I gave the cow a few hours’ 
rest, as well as myself, and then started to remove the foetus 
by laparotomy, but upon making my incision in the flank I 
found the peritoneum covering the uterus, and that, contiguous to 
it, in an inflamed state, and blood-tinted serum in the peritoneal 
sack. As it was beyond all reason to suppose that an animal 
in this condition could survive such an operation, I immediately 
destroyed her. 
I then removed the foetus, uterus and all through the flank, 
and found a double monstrosity, so complex that I will not 
attemp to name it. 
It consisted of one nearly completely developed body that 
had been lying in a lumbo-pubic position, and united to it at 
the abdomen and pubis was a second, short and smaller indi¬ 
vidual. The extremities of the first were all well developed, 
the near hind leg being drawn forward and under the off-fore of 
the second. The extremities of the second were all well 
developed except the near fore, which was short, crooked and 
directed backwards, and off of the scapula of this extremity 
was a projection about six inches long that looked as if it might.
