prickings, and sometimes occasions alarming symp- 

 toms, requiring the most efficient remedies to ex- 

 pel the worm from the intestinal canal. 



I proceed therefore to the examination of tliose 

 two species, which are the only ones found in the 

 human intestines.(o8) 



FIRST SPECIES. 



THE HUMAN ARMED TAENIA. 



§ XIV. The worm known by the name of tae- 

 nia cucurbitina, or solitary worm, (59) though de- 

 scribed and figured in several classical works of 

 natural history,(60) has nevertheless been the 

 cause of much uncertainty from the writings of sev- 

 eral men really illustrious, and which, in the opin- 

 ion of Blochn must be sufficient to humble the pride 

 of the human understanding. This worm is com- 

 mon with us,(6l) since the taenia most usually dis- 

 charged by our patients pertains to this species. 



This taenia, altogether peculiar to man, (62) 

 varies according to its age, food, length of its whole 

 body, and the bigness and dimensions of the ar- 

 ticulations or iuternodes, as Werner chooses to 

 call them. 



We see that these iuternodes are very slender 

 and delicate in the neck ;(63) almost square in the 

 body of the younger, and next below the neck in 

 those more advanced in age ;(64) in form of a paral- 

 lelogram in the oldest worms :(fi5) of the same 

 form and very broad in the largest taenia ;(6&) 

 oval and oblong in some '.(67) and lastly in others
