" Before we close our report of this very extraonlinary production, we 

 deem it ouiy an act of justice to the learned and laborious Editor, to mention, 

 that he has bestowed much trouble in d('ci[)lieviui^' the original manuscript, 

 and in procuring- a faiUituI version of its miscellaneous contents. Even the 

 fuc-nmiles of the rough drawings, though executed in a very different style 

 from the pretty plates of Mr. Ackermann's Repository, contribute, neverthe- 

 less, to the graphic and ghostly air of the whole performi'.nce.'" — Edinbiivh

Extracts from the Introduction. — '' I would propose, in the present advanced 

 state of science, thnt the mineral kingdom be divided into three provinces : 



1. PETRALOcy, or the knowledge of rocks, or htones which occur in large masses. 



2. LiTHOLOGV; the knowledge of gems aid small stones. 3. Metaixogv j of 

 the knowledge of metals. Each of the-e branches is even at present so im- 

 portant, and oflers such numerous topics of disquisition and i-eseareh, that ir* 

 the cour.-e of no long period a Professor of each will appear in Universities; 

 and each might occupy t'.ie sole jiursnit of an Author wf.o is zealous to make 

 discoveries, or to compose complete and classical works." — " In the present 

 Work it is lo be hoped that'the want of attention, <;are, or labour will not be 

 accused. The Author has sedulously employed the intervals often years ire 

 this j)rodnction, particularly three which he passed at Paris, where he had 

 constant opportunities of seeing the most opulent cabinets, and of conversing . 

 ■with men eniiricnt in the i:Ciince; as Paikin, Oili.lt-Laumont, Daubuissox, 

 and others : not to mention interviews with HAiiv and' wiih Werner, curing: 

 his short stay in that capiral. — ^He hopes the Wurk maj' at least asjiire to the 

 tiumble praise of utility, the chief ami of his labours."
