Anatomy. — Through the kindness of Mr. Brabazon, the excellent 



surgeon of Downpatrick, I had an opportunity of examining the fcetus 

 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. 



The thymus of moderate size, at the usual situation in the chest.
