502 Works on Natural History. 



which the author has expressed to us his great dissatisfaction. 

 Another number will complete the work; to which will be 

 added the description of the new species and genera, and which 

 has been the cause of the delay in the appearance of the latter 

 parts, of which such complaint has been made. 



Our third work is a Dictionary, somewhat in the same 

 style as Partington's Cyclopaedia of Natural History, but fat- 

 more extensive, four volumes being completed, and the letter 

 N only reached. The work is of the size and appearance 

 of the Penny Cyclopaedia, but with plates detached, and without 

 woodcuts. The price of the work is one of the most curious 

 things connected with it : eight pages and a well-engraved 

 plate are sold for a penny. Messrs. Guerin and Percheron 

 (well-known names) are employed in the entomological parts. 



The Suites de Buffon are a series of volumes, written by 

 authors especially devoted to the subjects selected by them, 

 comprising some of the most celebrated naturalists in France : 

 Desmarest, Fr. Cuvier, Andouin, De Blainville, Sander Rang, 

 Baron Walckenaer, &c, are engaged in this undertaking, 

 which promises to be of the greatest value. The plates are, 

 in general, well executed; indeed, some of them are very 

 superior productions. They will not, it is true, bear com- 

 parison with such works as those of Curtis, &c. ; but the price 

 is comparatively very small, a volume costing only 4J francs, 

 and a livraison of 10 plates uncoloured only 3 francs. 



Our fifth work is another exceedingly cheap production. 

 The " editeur," M. Dumenil, having brought to a success- 

 ful close a very cheap edition of BufFon, perceived the advan- 

 tages of completing the work by the addition of the articulated 

 animals, to be published on the same plan. The Count de 

 Castelnau, a distinguished entomologist, has undertaken this 

 task; and, from the smallness of the type and the conciseness 

 of the style, the two volumes, to which the work will extend, 

 are calculated to contain the matter of eight ordinary volumes, 

 accompanied with 100 plates, representing 800 or 1000 

 different objects from original figures, many of the drawings 

 of which we have seen in the hands of the author. The price 

 of the work is 4 sous (2d.) per livraison, including 16 very 

 closely printed pages in double columns, and 2 uncoloured 

 plates, representing a great variety of species, many for the 

 first time here figured from the author's cabinet. 



The Magasin de Zoologie is a work in which coloured 

 figures are from time to time published of new and chiefly 

 isolated species. Occasionally, however, valuable monographs 

 and memoirs are given ; as, for instance, the monographs of 

 the Pselaphidae, by M. Aube; that of the Trachyderides, by 

 M. Dupont ; and that of Phyllosoma, by the author.
