7. Mecherches sur les Poissons Fossiles, par UAgassiz, fyc. — 

 We mentioned this splendid work, and its plan and object, in Vol. 

 XXVIII, p. 193. We have received from the author the fourth livrai- 

 son, the third not having come to hand ; the first and second have 

 been before acknowledged. We have also received four of the folio 

 parcels of plates, containing in the whole eighty six plates. 



This learned and important work is carried forward by Professor 

 Agassiz with great spirit and energy, and we are happy to observe 

 that he is liberally and zealously assisted by naturalists and public 

 bodies, in different countries, and especially in the British islands. 

 We should be gratified, if he were cheered on, from this distant 

 country, by a liberal subscription. As yet, we are apprized of only 

 a few copies that have been ordered for the United States, but trust 

 that the number will be considerable in the end. 



The work will be of the greatest utility, in determining the differ- 

 ent species of fossil fishes, that have been or may, be developed in 

 our immense territory. 



8. Gradual rising of parts of Sweden, and of other countries 

 around the Baltic. — This fact, which has been observed for a cen- 

 tury past, has been ably investigated by Mr. Lyell, the eminent 

 EngHsh geologist, of whose observations there is an abstract in this 

 Journal, Vol. xxviii, p. 72, and the paper of Mr. Lyell, giving all 

 the most satisfactory details, has been since published in the Trans- 

 actions of the Royal Society, and received by us from the author. 



We have the pleasure, also, of presenting the opinion of an emin- 

 ent Swedish philosopher, whom we consulted on this point, and al- 

 though the letter, dated Stockholm, July 4, 1835, in which it is 

 contained, was not intended for publication, w^e do not hesitate to 

 cite the opinion. 



The fact of the gradual rising of the land, is considered by the 

 Swedish philosopher as fully established, on the basis of observa- 

 tion. Mr. Lyell, in the summer of 1834, having reviewed all the 

 marks cut in the rocks, and also other proofs of a similar nature, 

 returned to Stockholm, with the happy results of his investigation. 

 It is remarked by our correspondent, (than whom there is no more 

 competent judge,) that the phenomenon in question appears to be a
