VERMINOUS DISEASES. 



§ LXXIII. When the seeds of worms arc once 

 developed in the human body, health is more or 

 less deranged,(l) and the morbid symptoms which 

 then appear, are in proportion to the number and 

 size of the worms, to the sensibility of the parts they 

 occupy, and the general morbid diathesis which 

 takes place at the same time, whether as the cause 

 or effect of the worms. 



Hence it is that verminous affections are some- 

 times local, and sometimes sympathetic and gen- 

 eral. 



1. LOCAL AFFECTIONS FROM WORMS. 



§ LXXIV. These diseases are seated in those 

 parts of the body wherein the worm is developed 

 or to which it is transported. 



The physician observes the symptoms in the 

 part affected, and in distant parts of the body with 

 which an immediate relation subsists by means of 

 the communication of nerves, and is able to distin- 

 guish the symptoms peculiar to each species of the 

 worms already named.
