will indicate the connexion which exists between the organic 

 development of the earth, and that of different classes of ani- 

 mals. These ideas will be illustrated by an organic delineation 

 of each of the grand geological epochs. 



The " Researches on Fossil Fishes" will be printed in 12 

 numbers, each consisting of from ten to fifteen sheets of text in 

 q^uarto, and of 20 folio plates, at the price of 24 francs of France, 

 or 11 florins of Germany. 



The first will appear on 1st September 1833, with 20 sheets 

 of text, and 20 plates : it will comprehend the family of the 

 LepidotideSf and, besides the figures of all the fossil remains 

 which characterise the species, the skeletons of the living species 

 with which it is necessary to compare them, restored figures 

 will be given of one species of each genus. — The succeeding 

 numbers will appear, without intermission, every four months. 



6. The Internal Structure of Fossil Vegetables found in the Carboni' 



ferous and Oolitic Deposits of Great Britain. By H. T. M. 

 WiTHAM, Esq. F. R. S. & M. W. S. 4to. 84 pp. J 6 Coloured 

 Plates, containing 150 Figs. Black, Edin. and Longman, Lond. 



In this richly ornamented and interesting volume, besides a 

 reprint of former papers, there are many additional details illus- 

 trative of the structure of fossil trees, in different secondary for- 

 mations, and also of the formations themselves. An attempt is 

 made by Mr Witham to classify minutely some of the petrifac- 

 tions, which we consider premature, because such determinations 

 cannot be of much value until we are better acquainted with the 

 structure of the recent woods than is the case at present. We 

 therefore recommend to our author, and others engaged in this 

 inquiry, a close study of the structure of the recent woods, be- 

 fore instituting any more minute comparisons with the fossil ones. 



7. Boole's Work on the (Botany and Natural History of the Hima- 



htya Mountains, 



The intelligent author of this projected work is a sur- 

 geon in the India Company'*s service, who has enjoyed a lu- 

 crative appointment as one of their botanists. The work will 

 be principally devoted to the natural history of plants ; for, 

 as we have already often remarked in this Journal, the In- 

 dia Company have hitherto bestowed their munificent patron- 

 age almost entirely on botanists. " Although," says a valued
