Essays on some of the most important articles of the Materia Med- 

 ica, comprising a full account of all the new proximate principles, 

 and the popular medicines lately introcuced in practice, detailing the 

 formulas for their preparation, their habitudes and peculiarities, do- 

 ses and modes of administration ; with remarks on the most eligible 

 form of their exhibition : to which is added, a catalogue of medicines, 

 surgical instruments, &c. &c, adapted for a physician at the outset of 

 his practice, with the doses and effects attached to each medicine, 

 &c. fee. By G. W. Carpenter. Second edition, revised and en- 

 larged ; 8vo. pp. 320. Philadelphia, G. W. Carpenter. 



Mr. Carpenter's Essays are well known, and the present edition 

 is much improved. 



Elements of Geology, for the use of schools. By Wm. W. Ma- 

 ther; 18mo. pp. 139. Norwich, Wm. Lester, Jr. 



This is a judicious, correct, and perspicuous work, containing in 

 a small compass, a selection of many of the most important facts and 

 theoretical views in geology ; it is well adapted to the object for 

 which it was written. 



Mr. Mather has also published a Sketch of the Mineralogy and 

 Geology of New London and Windham counties, in Connecticut, 

 with a map. We cannot doubt that these are executed with Mr. 

 Mather's usual accuracy. 



Letters from the Canary Islands, by D. J. Browne, with a litho- 

 graphic view of the Peak of TenerifFe, and a Map of the Canary and 

 Madeira Islands, and a part of the coast of Africa. 



This is an instructive and interesting work, replete with valuable 

 information.

Prof. H. D. Dewhurst, of London, has recently published in one 

 vol. 8vo. with numerous plates the natural history of the Cetacean. 

 We have perused this work with much satisfaction ; we presume that 



it is the most complete account of these animals that has been pub- 

 lished. 



Mr. Dewhurst, has published also synoptical tables of an improved 

 nomenclature for the features of the cranium not only of man, but of 



anatomical 



rangement of the regions of the human body.
