414 JVotices of Recent and 



written for this edition ; for example, Zoology, (by Dr. Godman, of 

 Philadelphia, author of the well known Am. Nat. History) Mineral- 

 ogy and Chemistry. The departments of Political Economy and 

 Geography have also been much enlarged. Numerous entire arti- 

 cles of American and English Law have been introduced. In gen- 

 eral Biography, large additions have been made. The articles on 

 American Biography are entirely original, and have been furnished 

 by Mr. Robert Walsh, Jr., whose learning and taste are a sufficient 

 pledge of their value. The contributions under Mineralogy and 

 Chemistry, though perhaps not a complete system in themselves, in- 

 clude nearly every particular which relates to the common con- 

 cerns of life ; and the articles are ably and faithfully written. In 

 the nomenclature of minerals, the following course appears to 

 have been adopted. When the composition of a mineral is sim- 

 ple, consisting of a combustible and metal, as Sulphuret of Anti- 

 mony, or of an acid and an earth, as Sulphuric Acid and Barytes, 

 as in Heavy Spar, — it is treated of under the head of the principal 

 ingredient, as Antimony in the first instance, and Barytes in the sec- 

 ond. Thus, also, Gibbsite, which is an Hydrate of Alumine, is de- 

 scribed under that earth. In such cases, it is no doubt intended, in 

 the progress of the work, that reference shall be made from the min- 

 eralogical names of these substances to the chemical head under 

 which they are mentioned. Where the composition is less simple, 

 the mineral is noticed under one of its most popular names, as in the 

 case of Axinite and Agalmatholite. 



While we congratulate the public on the prospect of such a work, 

 we must be allowed to ask a favor of the publishers — that in the fu- 

 ture numbers we may be saved from such a constant use of the pa- 

 per knife.
