HUNTERS. 305 



To elucidate this matter, and render it 

 perfectly comprehensible/ with as little ic- 

 ference as possible to abstruse reasoning or 

 anatomical disquisition) let it be, understood, 

 that the internal coat of the stomach is so 

 plentifully portioned with branches from the 

 nervous system, that it may with great pro- 

 priety be termed the joint seat of irritability; 

 for, exclusive of the acting stimulus of the 

 cathartic medicines upon the extreme sen- 

 sibility of the nerves, so innumerably dis- 

 persed in their different ramifications, they 

 act also by irritation upon the mouths of the 

 lacteak and lymphatics, exciting a continued 

 and proportional emission of their contents 

 into the intestinal canal, so long as the sti- 

 mulative properties of the medicine may have 

 power to act ; during which such absorption 

 of Lymph, and the regurgitation of Chyle, 

 intermixes with, and is carried off by, the 

 excrements. 



By this constant stimulus upon the exqui- 

 site sensibility of the stomach and intestines^ 

 the vermicular motion is not only excited to 

 a more frequent discharge of its contents, but 

 its continual irritation of the vascular system
