Mr. Cruikshank’s Experiments 
EXPERIMENT XXII. 
Opened a doe the seventh day complete after the coitus : 
turned out, but with difficulty, one of the ova a little larger 
than in the last; the substance of the uterus over these ova was 
become thin and transparent, so at first sight you would ima-

EXPERIMENT XXIII. 
Opened another rabbit at the end of the third day : same

right side; at last, by drawing a probe gently over the fal- 
lopian tube on the left side, before it was opened, more than 
an inch on the side next the uterus, I pressed out several ova, 
which seemed to come from about its middle, as I began the 
pressure there, and the ova did not appear till the very last ; 
the amnion made a centre spot, and appeared small compared 
to the chorion ; no ova in the uterus. 
EXPERIMENT XXIV. 
Opened another at three days and a half : ovaria had the 
appearance as if the ova had not yet gone out; however, 
many of them were found in the uterus, and many in the 
tubes ; I got about six others were lost, from the great 
difficulty in slitting up the fallopian tubes without bruising 
the ova with the fingers or with the point of scissars; there
