^^ Dissection. On removing the dura mater, the 

 pia mater was seen elevated over the right hemis- 

 phere by a taraour, which was found to be an hy- 

 datid, about three inches long and two broad. It 

 was imbedded in the substance of the brain, by 

 which it was very lifierally supplied with numerous 

 minute vessels of the size of hairs, which were par- 

 ticularly abundant at the lower part. 



'^ The symptoms were supposed, by the medi- 

 cal attendants, to arise from some organic affection 

 of the head, as was afterwards demonstrated.''! 



IV. TREATMENT OF THE TRICOCEPHALUS. 



§ CLXII. Consumption, nervous epidemic fe- 

 vers, slow nervous, and mucous fevers, are the 

 chief diseases which seem at present (313) directly 

 to favour the development of this worm in the in- 

 testines. Inflammation and dilaeeration of the intes- 

 tines, occasioned by its presence (314), seem to orig- 

 inate rather from the prevailing atony of the viscera 

 than from the bite of the tricocephalus. 



§. CLXIII. So soon as those diseases, during 

 which this worm is developed, are cured, and the 

 tone of the intestines restored by a strengthening 

 diet, it is expelled ; because the circumstances 

 ■which favour the unfolding of the eggs, having ceas- 

 ed, they cannot again multiply in the human intes- 

 tines.
