A Second Edition of Dr. Ure's Dictionary of Chemistry, on 

 the basis of Mr. Nicholson's, has just made its appearance. 

 We spoke favourably of the First Edition in our 57th volume. 

 The reception it has met with (a large impression having been 

 sold off within two years) justifies the opinion we then ex- 

 pressed of the work. The new Edition, besides several 

 minute corrections, contains numerous additions which, very 

 judiciously, the author has rendered obvious by marking them 

 with a double asterisk. The following are among the new 

 articles: Acids — Butyric, Cevadic, Cholesteric, Delphinic, 

 Ellagic, Formic (factitious), Hydroselenic, Hyponitrous, Iga- 

 suric, lodo-sulphuric, Nitro-lucic, Nitro-saccharic, Phosphatic, 

 Pyromucic, Pyrocitric ; Acrospire ; Aphanite ; Carinthine ; 

 Chlorides of Carbon ; Chinconina ; Electro-magnetism ; Geo- 

 logy; Gieseckite; Inulin; lolite; Kollyrite; Lievrite; Chlo- 

 ride of Lime ; Liquetiiction of Gases ; Moiree Metallique ; 

 Peliom; Piperine; Quinina; Soap; Tea; Trachyte. — Besides 

 these additions, considerable insertions have been made in some 

 of the articles of the former edition. The work as a whole 

 reflects high credit on the author both in respect of his know- 

 ledge and his industry. 



Preparing for Publication. 



In the course of the ensuing month will appear the first two 

 volumes of The English Flora ; by Sir J. E. Smith, President 

 of the Linnajan Society, Sec. &c. In 8vo. — So much has been 

 tlone in Botany since the publication of the learned President's 

 Flora Britannica and English Botanij, especially with regard 

 to natural affinities ; and he has for 30 years past found so much 

 to correct in the characters and syngnjins of British plants, that 

 this is announced as an entirely original work. The language 

 also will be reduced to a correct standard ; \\\e genera reformed, 

 and the species defiued, from practical observation. Me are 

 well persuaded that tlie expectations of British bctanists will 

 not be disapj)ointed. 



Also, in one vol. 8vo, An easy Introduction to Lamarck's 

 Arrangement of the Genera of Shells; with illustrative Re- 

 marks, additional Observations, and a synoj)tic Table. By 

 Charles Dubois, F.L.S. 



Berthollet on Dyeing; translated from the last Parisian 

 edition : with Note?,'by Andrew Ure, M.D. F.lv.S. 8cc. It is 

 expected that this work will appear at the end of autumn.
