 IXCITANTIA. 



I. i. THOSE THINGS, which increafe the exertions of all 

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

 the fpirituous part of fermentated liquors, opium, and many 

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

 being afcertained. To thefe fhould be added the exhilerating 

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

 tion of heat, electricity, ether, eflential oils, friclion, and ex- 

 erci 



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 nervcus pains ; 

 and prevent the convulfions confequent to them. When given 

 internally they induce coftivenefs, and deep coloured urine ; 

 and by a greater dofe intoxication, and its confequenc 



II. OBSERVATIONS ON THE INCITANTIA. 



1. i. Opium and alcohol increafe all the fecretions 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 ; and the increafe of general heat, which 

 theie 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- 

 tcftinal and pulmonary mucus, have again their thinner parts 

 abforbed ; and hence, though the quantity of fecreted fluid 

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

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

 it is deeper coloured or of thicker confiftence, as the urine, al-
