the easrer proseoution of natural sciente. In this Itinerary we perceive n* 

 traces of that vanity for whicii its Author was subsequently too much di- 

 stinguished." — Monthly Revieic, March 1812. 



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

 deem it only an act of justice to tiie learned and laborious Editor, to mention, 

 that he has bestowed much trouble in deciphering the original manuscript, 

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

 facsimiles 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 performance.'' — Edviburiih

PETRALOGY: A Treatise om Rocks. By Jount PiN-KEUTO>r, 

 Author of Modem Geography, &C. Hanilsoniely printed in 2 lar"e 

 vols. 8vo. with 25 Vignette and other Engravings. Price 2i. 23. in 

 boards. 



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

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



1. Petralogv, or the knowledge of rocks, or stones w hioh occur in large masses. 



2. Lithology; the knowledge of gems and small stones. 3. METArxoGv j or 

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

 portant, and oilers such numerous topics of disquisition and research, that in 

 the course of no long period a Professor of each will appear in Universities- 

 and each might occupy the sole pursuit of an Author who is zealous to make 

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

 Work it is to be hoped that the v/aut of attention, care, or labour will not be 

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

 this production, particularly three which he passed at Paris, where he had 

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

 with men eminent in the science; as Pairin, Gillft-Laimont, Daubuissun, 

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

 his short stay in that capital. — He hopes the Work may at least aspire to the 

 humble praise of utility, the chief aim of his labours."
