In the beginning of summer 1778, I was conversing with 
Dr. Hunter on this subject, and said, “ I should like to repeat 
“ those experiments, now that lectures axe over, and that I

“ ments/’ said he, “ and I shall be at all the expence/" Ac- 
cordingly he carried me to Chelsea, introduced me to a man 
who kept a rabbit warren, and desired him to let me have as 
many rabbits as I pleased. I made the experiments ; and 
shall now lay a copy of my journal, then made, before this 
Society.

May go, 1778. I took a female rabbit, hot, (as the feeders 
term it) that is, ready to be impregnated, and disposed to re- 
ceive the male. This they find out, not by exposing her to the 
male, but by turning up the tail, and inverting part of the 
vagina : its orifice and internal surface are then as black as 
ink, from the great derivation of blood to these parts. Having 
run the point of a double-edged dissecting knife through the 
spinal marrow, between the atlas and dentata, she instantly 
expired. I preferred this method of killing her, because when 
the circulation stopped, the internal parts would be found, 
respecting vascularity, exactly as in the living body. Upon 
examination some time after, I found the internal parts of
