178 Dr. Haighton’s experimental Inquiry 
far from being evident, so that there was no danger of con- 
founding them with any recent mark that might happen. The 
tube on one side was cut through as before, but to my un- 
speakable mortification this rabbit was as barren as the for- 
mer, though tried several times during the space of three 
months. The generative organs were examined after death, 
and the appearances corresponded with those of former ex- 
periments. 
In this case, as well as in a former, I had an opportunity of 
comparing the shrunk state of the ovaries after death, with 
the plump and healthy condition before the mutilation ; and 
it affords an additional proof of that sympathetic connexion, 
or consent, between one part of the generative organs and 
another ; and shows that in the production of a new animal, 
the co-operation of different parts is necessary ; and further, 
that if the assistance of one part is wanting, the others, as if 
governed by a principle of intelligence, cease to continue their 
important work. But I was still in a state of suspense with 
regard to the end for which these experiments were instituted ; 
and such an uninterrupted succession of failures on a point so 
essential to my present inquiries, I confess tended but little to 
animate me in the pursuit. I was beginning to suspect that 
the barrenness consequent to the division of only one of the 
tubes, was as determined a law in the oeconomy of these 
parts, as it seemed to be in those cases where both tubes were 
cut through ; and that nothing could prevent this sterility ; but 
my contemplations were directed into another channel by the 
following experiment.
