the shortest. The specimen came from a dissecting-room sub- 

 ject, in one of the Southern States, which very probably may 

 have been a Negro. The Tcenia solium is found in England, 

 Germany, and America. The Botriocephalus latus is limited to 

 Switzerland and Russia, or, in the exceptional cases where it 

 has been found in Germany, the person from whom it was taken 

 had been to Switzerland. It remained to be determined if the 

 new genus was peculiar to the negro race. 



A discussion ensued as to the manner in which these 

 worms are introduced into the human body, the degree 

 of heat requisite to destroy their vitality in the j5rocess 

 of cooking, and the action of salt upon them. 



Dr. Weinland suggested that they might be introduced into 

 the human body with butter and other articles, which had been
