The first who looked upon the practical side of chemistry properly so 

 culled was Gentile Gentili de Foligno, whose treatise upon doses and pro- 

 portions of medicine may be looked upxm as a summary of medical chemistry, 

 which was very complete for the time at which it was composed. Next to 

 him come Antonio Quaiuer of Pavia, who manufactured artificial mineral 

 waters; Saladin of Ascoli, and Arduino of Pesaro, whose works enumerate 

 the substances having a mineral base which have been discovered by the 

 alchemists.

industrial arts at this epoch, as in the preceding ones, has been recorded in 

 special treatises, for by this neglect we have lost many ingenious processes, 

 whilst others, which might have been ready to hand, have only since been 

 discovered quite accidentally, and after long and laborious research. More 

 profit would have been derived from consulting the daily note-book of 

 an artisan of that period than the farrago of those who were engaged in the 

 great work ; i.e. the search for the philosopher's stone.
