present tapeworm to redevelop itself, the cure was 

 pronounced to be in all respects complete. 



In this connexion I have further to observe that 

 a careful examination of the "joints" of several 

 different tapeworms will convince you of their 

 liability to vary in character, so that the same 

 sets of segments, thus to speak, are not always 

 alike. In the examples before you some are 

 characterized by a few and others again by many 

 branchings of the uterine cavity. In well-marked 

 types, therefore, you would experience no difficulty 

 in referring some to the tapeworm derived from 

 beef and others to the form derived from pork. 

 Here, you perceive, is an extreme form which 

 I believe to be characteristic of the tapeworm 

 obtained from the ingestion of imperfectly cooked 

 mutton. "Measly mutton" and "measly beef" 

 are terms which will sound strange to those who 

 know of no other " measled meat" than pork ; but 

 my investigations (as you see in part by the speci- 

 mens of "measly beef" before you) have incon- 

 testably proved and verified the fact of the existence 

 of larval tapeworms in the most esteemed kinds of 

 animal food.
