It is obfervable, that both fows rather increafed in their 
number each time the older they grew, although not uni- 
formly ; the difference between the firft and laft in both ani- 
mals being confide rable. 
From the above table we find, that the fow with only one 
ovarium bred till fine was fix years old, from the latter end of 
1779 till September 1783, about four years, and in that time 
brought forth leventy-fix pigs. The perfect animal bred till 
fhe was eight years of age. In the laft, if conception depended 
on the ovaria, it was to be expected, that fhe would bring 
forth double the number at each birth ; or, if fhe did not, that 
fhe would continue breeding for double the time. We indeed 
find her producing ten more than double the number of the 
imperfed animal, and continuing to breed much longer.
