8. Recherches sur les Poissons Fossiles, par L’ Agassiz—Great 
work of Prof. Agassiz on Fossil Fishes ——We have had (through 
the kindness of the author, and of Mr. Mantell,) the pleasure of ex- 
amining the two first livraisons of this splendid work. ‘They are 
in large quarto, and contain nearly one hundred pages each. The 
plates are in large folio, and forty seven were sent with the two first 
livraisons ; they are well executed by lithography, and colored so as 
truly to represent the originals; and we suppose that they are, in gen- 
eral, intended to be as large asnature. M. Agassiz states in his pre- 
e that he has already ascertained that there are more than five 
hundred species* of extinct fishes; and he thinks that when the sub- 
ject shall have been fully examined, the number will be augmented 
toone thousand. He has examined more than ten thousand individ- 
a letter this day received, (Feb. 22, 1835,) from Prof. Agassiz, dated Neuf- 
hans Switzerland, Jan. 6, 1835, he states the number of extinet species already 
ascertained, as being agit kandred. He manifests the most lively interest to be- 
come acquainted with Saroigt localities of ichthyolites, and to receive speci- 
mens and descriptions of them; he has carefully noted all those published in this 
Journal, and in —_ works for ie country which he hasseen. We earnestly 
Solicit for him assistance of American Geologists.
