tion, 30, may be confidered as a comment od 

 the firft part of this general diflribution of medi- 

 cines, diftinguifhed by the term Sapida and the 

 prefent t-bejs as an explanation of a large divifion 

 of the Olida, here called Graveolentia^ from their 

 flrono; and ungrateful fmell. 



The combinations of Sapids and Olids are innu-^' 

 merable but that fimples, ftri6tly of the latter 

 kind, do, in a fudden and extraordinary manner, 

 exert their influence on the nerves, is certain ; 

 though our author contents himfelf with the fadl, 

 without enquiring whether the fundions of the 

 nerves are performed by means of animal fpirits, 

 by vibration, the medium of eledlricity, or by any 

 other way. And from the Graveolentia^ which are 

 the fubjed of his thefis, he juftly obferves, thac 

 we derive fome of the mofl: powerful remedies. 

 Of thefe he gives a catalogue, dividing them into 

 three clafles : i. Subinsipid. 2. Acrid. 3. Bit- 

 ter : each of which is fubdivided into two orders, 

 as the fubjeds differ in degrees of ftrength. The 

 Subinjipid contains chiefly the Narcotics : the Acrid 

 feveral of the purging, and fetid roots ; the fetid 

 gums, and carminative feeds : the Bitter con* 

 tains others of the purging roots and leaves ; and 

 fome of the bitter herbs. Under each, the au- 

 thor fpecifies, in technical terms, very briefly, the 

 quality, and the difeafes to which it has been ap- 

 propriated. 



He then prefents us with a concife, but very in- 

 ftrudlive theory, of the operation of this divifion of 

 the Olida ; leaving to the confideration of others, 

 the Suaveokntia : after which, follows a general 



pathology
