to discover the Ova of Rabbits. 
and divided into two as it came to the mesentery ; could not 
see the urachus or allantois well, nor the membrane to which 
the omphalo-mesenteric artery goes. 
EXPERIMENT XV. 
Opened a doe the fifth day after coitus : found the ova loose 
in the uterus, to the number of six ; even these had a lesser 
coat in the inside, corresponding to amnion. None in the tubes. 
EXPERIMENT XVI. 
Opened (fourteen days after the operation) the doe whose 
fallopian tube I tied. The uterus of the right side was the 
size of the sixth day ; the ovarium and uterus had gone back- 
wards as to the process, and there was no appearance of 
foetus ; though placenta was very evident on the left side, there 
was no appearance of conception in the uterus; no placenta; 
the fallopian tube was very large, soft, and tender ; the ova- 
rium twice the size of that on the other side, red, and covered 
with extravasated coagulable lymph ; there was an hydatid in 
the course of the tube, containing a clear fluid, but nothing 
like foetus. I suspect that tying the tube prevented the ova 
on this side from coming out of the ovarium, and that though 
they rather increased in the ovarium, the process soon stopped; 
that the process went on, however, in the other side for a few 
days, and then stopped likewise : there was universal inflamma- 
tion about the uterus and colon of the left side, with great quan- 
tities of white extravasated coagulable lymph ; there was water 
in the abdomen, and all the appearance of peritoneal inflamma- 
tion. This process seems to give but little pain, for the animal 
at the time she was killed was eating and looking as usual.
