the eager prosecution of natural science. In this Itinerary we perceive n* 
traces of that vanity for which its Author was subsequently too much di- 
stinguished.” — Munthiy lit-view, March 1812. 
“ Before we close our report of this very extraordinarj'- production, we 
deem it only an act of justice to t!ie learned and laborious Editor, to mention, 
that he has bestowed much trouble in deciphering the original manuscript, 
and in procuring a faithrui version of its miscellaneous contents. Even the 
Jac-similes 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.”- — Edinburgh

Author of Modern Geography, &c. flandsomely printed in 2 large 
vols. 8vo. vyith 25 Vignette and other Engravings. Price 21. 2s. in

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 stories which occur in large masses. 
2. Lithology; the knowledge of gems and small stones. 3. Metallogy; or 
the knowledge of metals. Each of these branches is even at present so im- 
portant, and offers such numerous topics of disquisition and research, that ii> 
the course of no long period a Professor of each will appear in Universities; 
and each might occupiy the sole pursuit of an Author who is isealous to make 
discoveries, or to compose complete and classical works.” — “ In the present 
Vfork it is to be hoped that the w'ant of attention, care, or labour will not bo 
accused. The Author has sedulously employed the intervals of ten years in 
this production, particulariy 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 Pa'irin, GilliiT-Laumont, Daubuisson, 
and others ; not to mention interviews with Hauy and with Wermeu, 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.”
