When on the contrary fome branches of the abforbent fyttems 

 have their motions inverted in conference of the previous ex- 

 haustion of their fenforial power by any violent ilimulus, other 

 branches of it have their abforbent power greatly increafed, 

 Hence continued vomiting, or violent cathartics, produce great 

 abforption from the cellular membrane in cafes of dropfy 5 and 

 the fluids thus abforbed are poured into the ftomach and intcl* 

 tines' by the inverted motions of the lafteals and lymphatics, See 

 ge&, XXIX, 4, and 5.

 rejected with the firft effort, AU emetics are (aid to act with 

 greater certainty when given in a morning, if an opiate had 

 been given the night before. For the fenforial power of irrita* 

 tion of the ftomach had thus been in fome meafure. previoufly 

 exhaufted by the ftimulus of the opium, which thus facilitates 

 the action of the emetic ; and which, when the dole of opium 

 has been large, is frequently followed on the next day by (pan* 

 faneous fjcknefs and vomitings, as after violent intoxication.

 fane people, and from thence to twenty to in fane patients, will 

 qnfwer moil of the ufeful purpofes of emetics j but nothing 

 equals the digitalis purpurea for the purpofe qf absorbing w ., 

 from the cellular membrane in the anafarca pu!monum 3 or 'hy- 

 drops pectoris,. See Art, II. 3, 7, 



II. Violent cathartics. 1, "Where violent cithartics are re* 

 quired, as in dropfies, the fquill in dried powder mads into 

 (mail pills of a grain, or a grain and * half* one to be given

 grain of emetic tartar di/Folved in an ounce- of peppermint-Wat*: , 

 and given every hour, till it operates, Scammony, and other 

 ftrqng purges, are liable to produce hypercatharfis, if they 

 not nicely prepared, and accurately w rl, 2nd are * 



dangerous in common practice. Gamboge is uncertain in it? 

 effects, it has otherwife the good propertv of f being taftele-fs } 

 on that account fome preparation of it might be uf< r clrlL
