EXPERIMENT. 
A full grown virgin rabbit had one of the tubes divided at 
a little distance from the extremity of the cornu uteri. The 
wound soon healed up, and its health was soon restored, but 
it betrayed no disposition for the male. I attributed it in part 
to the coldness of the season, for it was in the middle of De- 
cember, 1794; but the effects of its inclemency were much 
moderated by having a fire in the room during the day. I 
kept her until the first of May ; during this interval the male 
was frequently offered to her, but she always refused, except 
once in February: it however was unproductive. 
From examination after death, it appeared that the divided 
tube was completely obliterated, but the other was sound : both 
ovaries were evidently shrunk, proving, in addition to my pre- 
vious observations, that their actions had been languid. 
The result of this experiment disappointed me much ; for 
no reasoning a priori had led me to entertain the smallest sus- 
picion that a mutilation of one side only could destroy the 
harmony of the whole uterine system. But my disappointment 
originated chiefly from the apprehension that this effect would 
be uniform, that it was the result of a determined law of the 
part; and if so, it formed an insuperable obstacle to my research. 
Its importance to my project was too great to be discouraged 
from a single obstacle ; therefore injustice to my undertaking, 
I was in some measure compelled to push the inquiry to such 
an extent, as should enable me to say with precision, whether
