VERMINOUS DISEASES. 14$ 



beautiful experiments of Masca^ni, CruickshanJc, 

 and of Assalinif as well as since the pathological 

 observations collected by Soemmering (S4) and by 

 Wolffy{25) physicians are more than ever convinc- 

 ed of the influence of the system of lymphatic ves- 

 sels over the functions of the animal economy.(S6) 



^ LXXXV. The vesicular worms scattered 

 through the substance of the brain of sheep, render 

 these animals vertiginous, meager and stupid ;(S7) 

 living in the ventricles of the human brain, we have 

 observed that they are the cause of apoplexy. (28) 

 In these cases we should also consider the mechani- 

 cal effects they produce on this viscus as depending 

 on the presence of foreign bodies, since they must 

 also contribute to excite all the phenomena which 

 result from the irritation of this organ. Vesicular 

 worms have also been found along the plexus cho- 

 roides of the brain, in a man, who, during his life, 

 was subject to very frequent vertigo, and to tingling 

 of the ears. (^9) In the hydrocephalus internus of 

 children, vesicular worms are ordinarily in the sub- 

 stance or ventricles of the brain. (30) In encysted 

 dropsy we also observe an infinite number of these 

 worms, at least if some practitioners of merit are 

 not deceived. (31) With Pallas^ we regard them 

 as causing this and similar diseases. 



§. LXXXVI. Hydatids have been found in the 



matter of expectoration,^- in urine, and in fecal 

 discharges. (32)
