Anatomy.—Through the kindness of Mr. Brabazon, the excellent 
surgeon of Downpatrick, I had an opportunity of examining the foetus 
of which the measurements have just been given. As the dissection 
was suddenly stopped, the details are imperfect, though accurate as 
far as they go. The skin was of a dark leaden colour, and the 
blubber on the sides of the body about half an inch thick. ‘There 
were soft fringes or processes of the gums, corresponding in situation 
and number to the coming teeth.
