The employment of chemistry by the miner alo- 

 gist, as a means of analysing the various substances 

 which come before him, w^as first undertaken in 

 the century under review. M argr a af and Pot r, 

 af Berlin, were among the earliest adventurers iii 

 this new field of inquiry. They were succeeded 

 by Neumann, Bergman, and Scheele, who dis- 

 played great industry, address, and perseverance, 

 in the same course of investigation, and went 

 much further than their predecessors. To these 

 may be added Klaproth, Sage, Vauquelin, and 

 many more, to whom we are indebted for many 

 new facts, and refined experiments, on the che- 

 mical properties of mineral bodies. 



Since the grand revolution in chemical doctrines 

 and language, effected by the labours of the French 

 Academicians, as above detailed, the new opinions, 

 and the proposals of further reform in this science, 

 have been numerous. Indeed, during the last 

 fifteen or twenty years of the century, the number 

 of students and experimenters in chemistry has 

 been so prodigiously great, and the new plans an- 

 nounced for explaining and expressing its princi- 

 ples so multiplied and various, that a simple ca- 

 talogue of them would fill many pages. All that 

 can be attempted in this brief sketch, is to men- 

 tion a few of those who have rendered themselves 

 conspicuous by their inquiries or publications on 

 chemical subjects. 



A new nomenclature of chemistry was proposed, 

 in 1796, by Professor Dickson, of Trinity College, 

 Dublin, and approved by his illustrious country- 

 man, Mr. Kir wan. In this plan of chemical 

 denominations there is an attempt to unite the 

 advantages of both the principal systems, between
