to deny, and when they do, we cannot now be at a loss for 
a mode of accounting for their doing so. 
With the following well authenticated instances of this 
kind that have come under my own observation, I shall close 
this Lecture.

A lady while pregnant with her tenth child, the former 
nine being perfectly formed, was robbed in the dusk of the 
evening near Woolwich by an artillery man who had a hare

she did not recover from it for several days ; when brought 
to bed the child was found to have a hare-lip. I was called
