APPENDIX 



PRINCIPAL HUMAN WOiniS, 



§ LIY. Several eminent naturalists(231) have 

 spoken, in their writings?, of some other Avorms 

 which are rarely found in the human body, and 

 they have described them as particular species. 



Though tlVe liistory of these worms does not per- 

 tain directly to medicine, yet I deem it very impor- 

 tant that physicians should know all the varieties ot 

 the worms of the human body, besides those which 

 are peculiar to it, and may prove hurtful, agreea- 

 bly to the observations which have been already 

 collected. 



In my opinion all these worms may be consid- 

 ered as varieties of those we have described, or as 

 accessory worms,(S82) which are not indigenous to 

 the human system, but which sometimes introduced 

 there, occasion peculiar and severe diseases. 



§ LV. We should regard as varieties of the 

 worms indigenous and peculiar to the human body, 

 the membranous taenia,fS33) the ascarides vermic- 

 ulares, discovered by Brugnatdlii^iLZ^) in the va- 

 gina of a woman, the ascaris lumbricoides of Ro- 

 sensteinf{2S5) the stomach worm of Pereboom/2SQ) 

 etc.
