the tone of which, towards the memory and discoveries of Cuvier 
every lover of science must deplore, we look in vain for any acknowl- 
edgment for the source of the beautiful generalization of the relation 
of the particular forms of the astragalus, to the parity or imparity of 
the hinder digits, or any ascription of the credit due to a prevision, 
which it had been the good fortune of the author of the ‘ Osteographie’ 
to verify.” M. de Blainville both in his published works and public 
lectures, has not only treated the memory of Cuvier with neglect, but 
seems to have been actuated by a worse spirit than that of a a. 
some detail in our last. Part third, sustains all that we observed with 
regard to the elegant character of the engravings and their finished 
accuracy and fullness of detail. The plates of this part illustrate Ge- 
ology, Physical Geography and Botany. ‘The principles of geology 
are well brought out by drawings that speak to the eye. Stratification, 
horizontal and disturbed, and structure of various kinds, are illustrated 
bald outline, but in pleasing landscapes an nes, executed in the 
best style of the art. The botanical department is illustrated with like 
beauty and fullness. On 55, we recognize the magnificent sketch 
tion by Captain Wilkes, volume v, p. 26; on plate 56, a Palm grove on 
the Island of Fakaafo, from the same volume, p. 14, though with some 
added shrubs and trees that are never found on Coral Islands ; on plate 
47, a view of the Antarctic continent from amid the icebergs, from the 
same work, volume ii, p. 325, besides reduced copies ofthe sketches of 
some of the craters of the Sandwich Islands, from volume 4, of Cap-

6. Foster's Complete Geological Chart.—A_ large geological chart 
under this title, some six feet or more square, largely lettered and well 
_ Yarnished, has recently been seen by us. [It emanates from Albany, 
- Y., and appears to have been intended to illustrate geology to the 
schools of that state. Strange to say, there is not one word of New 
York geology to be detected in it, and not even a hint with regard to 
American rocks. With some truth (in lineal descent from a well 
known French chart), it combines much that was formerly supposed to
