166 Miscellaneous Articles of Foreign Intelligence. 
I purpose in a future number to give an account of the 
New-Haven and Milford Marble, which is equally inter- 
esting in its relations to the arts and to geology.— Ed.

In France—The study of Organic remains continues to 
advance rapidly. Brongniart is at the head and is the most 
able man for Floetz (or secondary) formations, but for 
Primitive, Brochant is superior. Brongniart carries his 
views about coal formations so far, that he looks upon them 
as great Fresh Water deposits, from their sometimes con- 
taining shells like the lime or river water shells; they are 
found for example at Entreveres, in the Alps, at Falkirk, 
and Alloa in Scotland, &c. On the other hand, following 
this step, Mineralogists have already shown the great aggre- 
gation of rolled flints and sand between the Jura and the 
Gres, to be a succession of fresh water and salt water depo- 
sitions, or, at least three or four very different deposits ;— 
and the Jura limestone they have divided into three, lime- 
stone with Gryphites, and two others above which is the 
third Floetz limestone of Jameson. 
Brongniart delineates and describes all the impressions 
of plants which he can get, and every lover of the Science 
must wish that he may be enabled to publish so fine a work. 
Daubuisson has in the press, Elements of Geology in twe 
vols. itwill be a good work. 
Humbolt is preparing a similar work. 
Beudont, who has already, in the Journal des mines, given 
many interesting facts respecting the crystalization of salts 
under different circumstances, is about publishing a journey 
through Hungary, where he spent six months, and found 
beside primitive formations, a newer Sienitic and Volcanic 
Porphyry formation ; a red sand stone, with masses or beds 
of pitchstone, precisely like that of Arran, excepting that 
the latter occurs in veins ; a chalk formation, a part of the 
Paris formation, and a volcanic formation deposited and ar- 
ranged in beds by water; the pumice, in these singular wa- 
tery arrangements having often, at first sight, the appearance 
of chalk ; his work will throw much light on Geology.
