 INCITANTIA, 



1. i. Those things, which increafe the exertions of all 

 the irritative motions, are termed incitantia. As alcohol, or 

 the fpirituous part of fermented liquors, opium, and many 

 drugs, which are ftill efteemed poifons, their proper dofes not 

 being afcertained. To thefe mould be added the exhilarating 

 paflions of the mind, as joy, love : and externally the applica- 

 tion of heat, electricity, ether, eiTential oils, frifUon, and ex- 

 ercife. 



2. Thefe promote both the fecretions and abforptions, in- 

 creafe the natural heat, and remove thofe pains, which origin- 

 ate from the defect of irritative motions, termed nervous pains ; 

 and prevent the convulfions confequent to them. When given 

 internally they induce coftivenefs, and deep coloured urine j 

 and by a greater dofe intoxication, and its confequences. 



II. Observations on the Incitantia. 



1. 1, Opium and alcohol increafe all the iecretions and ab- 

 forptions. The increafe of the fecretion of fenforial power ap- 

 pears from the violent exertions of drunken people ; the fecre- 

 tion of fweat is more certainly excited by opium or wine than 

 by any other medicine j and the increafe of general heat, which 

 thefe drugs produce, is an evidence of their effect in promoting 

 all the fecretions ; fince an increafe of fecretion is always at- 

 tended with increafe of heat in the part, as in hepatic and other 

 inflammations. 



2. But as they at the fame time promote abforption ; thofe 

 fluids, which are fecreted into receptacles, as the urine, bile, in- 

 teftinai and pulmonary mucus, have again their thinner parts 

 abforbed; and hence, though the quantity of fecreted fluid 

 was increafed, yet as the abforption was alfo increafed, the ex- 

 cretion from thefe receptacles is lefTened ; at the fame time that 

 It is deeper coloured or of thicker confidence, as the urine, al-
