 alleged extremely delicate character of the pro-

 you call it Tcenia canina, T. elliptica, or T. cucu- 

 merina, it perhaps matters little) is occasionally 

 liable to infest the human body. 



That the statements of others in respect of the 

 specific characters presented by particular forms of 

 human Tania cannot always be relied on I have 

 already shown, and in this connexion few seem to 

 bear in mind the very remarkable malformations 

 which occur amongst the tapeworms. In this 

 purely professional course I cannot go fully into 

 the matter, but I may mention that only very re- 

 cently I had a case of Tcenia solium where several 

 of the proglottides had two sexual papillae arranged 

 precisely as in the cucumerine tapeworm. The odd 

 thing is, moreover, that this patient also came from 

 Liverpool, a circumstance which naturally seems to 

 weaken the verbal evidence produced in the pre-

 in the human subject. The facts are as follow I-
