the changes they undergo. Having dissected a 

 rabbit, half an hour after impregnation, he per- 

 ceived the horns of the womb, that go to embrace 

 and communicate with the ovary, to be more red 

 than before ; but no other change in the rest of 

 the parts. * Having dissected another, six hours 

 after, he perceived the follicules, or the mem- 

 brane covering the eggs contained in the ovary, 

 to become reddish. In a rabbit dissected after 

 twenty-four hours, he perceived, in one of the 

 ovaries, three follicules, and in the other, five, 

 that were changed ; being become, from transpa- 

 rent, dark and reddish. In one dissected after 

 three days, he perceived the horns of the womb 

 very strictly to embrace the ovaries ; and he 

 observed three of the follicules in one of them 

 much longer and harder than before : Pursuing 

 his inquisition, he also found two of the eggs ac- 

 tually separated into the horns of the womb, and 

 each about the size of a grain of mustard-seed : 

 these little eggs were each of them enclosed in a 

 double membrane, the inner parts being filled 

 with a very limpid liquor. After four days he 

 found in one of the ovaries four, and in the 

 other five follicules, emptied of their eggs ; and 

 in the horns correspondent to these, he found an 

 equal number of eggs thus separated : these eggs 

 were now grown larger than before, and somewhat 

 of the size of sparrow-shot. In five days the eggs 

 were grown to the size of duck-shot, and could 

 be blown from the part of the womb where they 

 were by the breath. In seven days these eggs 

 were found of the size of a pistol bullet, each
