xil The P R E F A C E. 



medicines i?t general are ajlrange cojjt- 

 pound or jumble of various and difcordant 

 ingredie?ifs ; fuitable enough to the then 

 reigning fafiion of prefcribing where 

 the falfe pomp of nimierous ingredients 

 inhanced their value ; but by no 7neam 

 agreeable to the later improvements^ or 

 to that jufl fimpli city that fo remarkably 

 adorns thepraciice of modern phyfck and 

 furgery. 



THE author has no other apology 

 to make for d'gefting this piece, and 

 the obfervations and reflections he has 

 tjiteifperfed throughout the whole, than 

 his good intention to refcue the prac- 

 tice of fan^iery out of hands that fo 

 much abufe it ; and to cc?2vi7tce gentle^ 

 men^ that as it is founded on rati-- 

 07tal principles, it is neither iinbecom- 

 ing their notice, or miworthy their 

 ftudy : and he thinks he has reafon^ 

 from fome late attempts, to hope, that 

 it Will foon beco?ne as cujiomary for 

 ' gentlemen to go through regular courfes 

 ofjarrieyy, as it is for phyficians and 

 furgeons through thofe of chemifry and 

 anatomy.
