the Kingdom of Austria by Professor Zepharovich, and the Minerals 

 of Switzerland by Dr. A. Kenngott, — both of which include under each 

 locality a description of the mode of occurrence, associated minerals, 

 etc., of each species, — this Directory is a simple statement of locali- 

 ties ; and though there are many omissions and a few errors, it will 

 probably be found by many to be nearly as useful a work for 

 British, as the more elaborate Continental ones are for Swiss and 

 Austrian localities. 



With regard to the old Cornish term for a mine, Huel, the author 

 says, " Huel probably became corrupted first from its similarity of 

 sound with the Saxon weal, especially as mines were looked upon as 

 a fertile source of weal or wealth. This next became wheal, and so, 

 having lost its original signification, a double corruption has some- 

 times crept in, as Wheal Maria Mine, where the word 'mine' is thus 

 repeated twice." It is time that this error should be corrected, and 

 accordingly Huel has been adopted throughout as the correct spelling ; 

 the word still being in use in many parts of Brittany with the same 

 meaning. 



The introduction includes a table of the mineral species found in 

 the British Isles, accompanied with the essential constituents of each 

 and their amounts. 



The mineral localities are grouped in the same county around 

 their respective post-towns, with the exception of those of Cornwall, 

 which, owing to the great number of mines, are referred to their 

 respective parishes. In all cases where positively known, the forma- 

 tion is given, another point of interest in such a list. 



Preceding an appendix, which includes a list of geological forma- 

 tions with the minerals peculiar to or characteristic of their respective 

 strata, is a list of localities of pseudomorphs, to which certainly 

 numerous additions will have to be made. 



Such a work as this has long been a desideratum, and Mr. Hall 

 may be congratulated on having succeeded so well in bringing his 

 heterogeneous and often contradictory materials into so intelligible 

 a shape. 



We only hope that the author's request with regard to omissions 

 or errors will be liberally responded to by local collectors and 

 others, in order that the next edition, which is promised, may repre- 

 sent more completely still the mineral productions of all British 

 localities.

 Influence on the Oceanic Atmospheeio and Land-Currents, 

 AND THE Distribution of Eaces. By Geo. Catlin. Loudon, 

 1860. 8vo. pp. 228. Triibner & Co, 8 and 60, Paternoster Eow. 



CATLIN, the hero of our boyhood, the historian of the North 

 American Indians, comes before us here in a new character, 

 as a writer on physical geology, geography, and ethnography ; and 

 although we confess to a feeling of fond regret in not meeting with 

 a single buffalo-hunt, or a Pawnee chief in his war-paint in the book
