©uvier’s great work, (the new edition of which we have 
already: mentioned,) M. Brongniart’ is engaged in revising 
it for that work. We are informed by him ‘that it will be 
greatly enlarged, and that he will referto it the analogous 
formations’ which he has had occasion to observe, or. to 
become acquainted with in other countries. The depart- 
ment relating to chalk is already executed, and the au- 
thor has described and figured all the fossil shells characteris- 
tic of that formation—four plates atleast are requisite for this 
‘subject.’ From the chalk he will pass to the lime stone of 
the Jura and of transition. 
‘In executing the memoir on the Vincentin, and the pein 
just mentioned, the author was obliged to have many figures 
delineated, and to digest many descriptions. This has af- 
forded him materials for another work which is a very great 
desideratum in the geological science : we mean—. 
64. 4 new elementary work on ail shells with a particu- 
lar reference: to Geology.—Every person conversant with 
geological investigations, must have found extreme incon- 
veitience from the want of a good elementary work with 
plates exhibiting the various fossil reliquia in a manner so 
distinct; that they maybe recognized by a learner. \The 
splendid work of Parkinson, embracing a part of this sub- 
ject, is too expensive to be in’ many “hands, and that of La 
Marck is little known’ in this country. 
We are therefore peculiarly happy in learning: aa M, 
Brongniart, that he is himself engaged in the prepamtan of 
such a work, which is already far advanced. 
“The fossil shells characteristic of the geological forma 
tions to which they belong, are enumerated, described, and 
figured, with the greatest attainable exactness. | ‘The sub- 
jects are arranged in zoological order, and will thus consti- 
tute an elementary work in that department. It may be ex- 
pected to appear about the end of the year 1822;, We have 
seen some of the prints executed for the above work: they 
are’ beautifully done in the Lithographic method; and when 
accompanied by their appropriate descriptions, we cannot 
doubt that they will prove perfectly satisfactory. = + 
‘We shall wait with much impatience for the appearance 
of this work, which will probably be even more useful i in this 
oy than j in as oo |S
