died. They appear to me to be the larvae of feme infeit, but 

 of what particular fpecies I am not naturalift minute enough to 

 determine. The large one appears very fimilar to the larva of 

 the common beetle. We have many inftances related by va- 

 rious authors, of different fpecies of worms difcharged from the 

 inteftinal canal ; but of the different defcriptions I have read, or 

 fpecimens I have feen preferved in anatomical colledions, none 

 have flruck me as in any degree fimilar to thofe difcharged by 

 the patient whofe cafe has been jufl related. It is probable, as 

 has before been mentioned, that the worms difcharged were 

 the larvas of fome infe£t which does not ufually depofit its eggs 

 in any part of the human frame ; but which having been acci- 

 dentally depofited in, or conveyed into the body, were hatched, 

 and acquired the fize and form we have delineated. 



That flies of various kinds depofit their eggs in living ani- 

 mal bodies, and that thefe eggs are by the heat of the animal 

 hatched and transformed into maggots, is evident from the in- 

 ftance of many fo produced in the redum of horfes, and backs 

 of black cattle. The human body being in general better covered, 

 and better defended from the attempts of fuch infedls, does not 

 exhibit fo many inftances of this nature. Still however it is 

 liable to their attacks. Many cafes have been publifhed of va- 

 rious infects being hatched, and producing excruciating pain in 

 the antrum maxillare, and other cavities leading to the nofe. 

 Other worms, evidently the larvae of external infeds, have been 

 difcovered in the inteftines : And in the Medical Commenta- 

 ries for the year 1787 there is a curious cafe of fome exifting 

 under the fldn.
