 A New System of Chemical Nomenclature; exhibiting not only

Mr. Swainson's Exotic Conchologj"^, the publication of 

 which has been long suspended on account of the various acci- 

 dents to which the state of lithography in this country had 

 subjected the author, is about to be continued, and the Plates 

 of the fifth number are now printing by Messrs. Rowney and 

 Foster. Mr. Swainson, anxious to attain as near to perfection 

 as possible, has, in consequence of improvements in lithogra- 

 phy, which will do more justice to his excellent drawings, 

 re-engraved most of the plates already published ; and liberal- 

 ly offers to give early purchasers of the work the option of 

 changing their old plain copies for the new and improved en- 

 gravings. We have been favoured with a sight of the new plates, 

 which, in point of design, accurate delineation, and delicate 

 finishing, claim our highest commendation: and this is also due 

 to the scientific descriptions by which they are illustrated. 



The Natural History of Meteorites, or of those remarkable 

 Masses of Iron, and of Earthy and Metalhc Compounds, which,

 tries ; and an Appendix of Tables, &c. By E. W. Brayley,
