SECT XXIX. 10. RETROGRADE ABSORBENTS. 595 



I then patted a ligature round feveral branches 

 Of lacteals, aaJ inhaled tne n much with a knife 

 beneatn the ligature, but could not make them re- 

 gurgitate their contained tiuiJ in o tne boweis. 



I am not in JeeJ certain, that the nerve was not 

 at the fame time included in the ligature, and thus 

 the lymphatic rendered unirritable or iifelefs ; but 

 this however is certain, that it i> n >t any quantity 

 of any ilimulus, Which induces the veflels of animal 

 bodies to revert their motions ; but a certain quan- 

 tity of a certain itimulus, as appears from wounds 

 in tlie ftomach, which do not produce vomiting 5 

 and wounds' of the inteftines, which do not produce 

 the cholera morbus. 



At Nottingham, a few years ago, two fhoem\ke*-$ 

 quarrelled, and one of them with a knife, which 

 they ufe in their occupation, dabbed his companion 

 about the region of the ftomach. On opening the 

 abdomen of the wounded man after his death, the 

 food and medicines he had taken were in part 

 found in the cavity of the belly, on the outride of 

 the bowels ; and there was a wound about half ari 

 inch long at the bottom of the ftomach ; which I 

 fuppofe was diftended with liquor and food at the 

 time of the accident ; and thence was more liable 

 to be injured at its bottom : but during the whole 

 time he lived, which was about ten days, he had no 

 efforts to vomit, nor ever even complained of being 

 fick at the ftomach I Other cafes umitar to this are 

 mentioned in the philofophical tranfadlions. 



Thus, if you vellicate the throat with a feather, 

 naufea is produced \ if you wound it with a pen- 

 knife, pain is induced, but not iicknefs. So it the 

 foles of the feet of children or their armpits are 

 tickled, oonvulfive laughter is excited, which ceafes 

 the moment the hand is applied, fo as to rub them 

 more forcibly,
