to discover the Ova of Rabbits. 
5thly. The ovum comes into the uterus on the fourth day. 
6thly. De Graaf did not see the foetus till the tenth day; I 
saw it on the eighth. 
7thly. These experiments explain what is seen in the human 
female. For, 
A. I shew a child, at lectures, which remained in the ovaria 
till it was the size of the fifth month ; its fluids were all wasted, 
and its solids were hard and compressed into an oval form ; it 
had the chorion and amnion, its chord and placenta. 
B. I also have in my possession the uterus and ovaria of a 
young woman who died with the menses upon her; the exter- 
nal membranes of the ovaria are burst at one place, from 
whence I suspect an ovum escaped, descended through the 
tube to the uterus, and was washed off by the menstrual blood. 
C. The ovum sometimes misses the fallopian tube, falls into 
the abdomen, and forms the extra-uterine foetus ; this some- 
times grows to its full size, labour pains come on at the ninth 
month, the child may then be taken out alive by the Caesarean 
section ; or, dying and wasting, but not putrefying, may remain 
without much inconveniency to the mother for many years. 
D. The ovum, although it has gone some way down the 
fallopian tube, may be arrested in its course and become sta- 
tionary, and form what is called the fallopian tube case. A 
remarkable case of this kind is given by Dr. Hunter, in his 
book on the gravid uterus, where the tube burst, and the mo- 
ther bled to death. 
E. Lastly; the ovum comes into the uterus, where there is 
room for its enlargement, and a passage for its exit from the
