Mallet, the Chemist of the Survey, and under his direction the re- 
have been brought out. The volume treats briefly of the geology _ 
the northern part of the State, giving some facts relating to the Silu- ~ 
tian, Devonian and Carboniferous rocks, and also the metamorphic, with 
particular descriptions of iron ores and other economical products. It 
_ also mentions local details on the newer deposits of the State. eim- . 
t statement is here made that the “ Gnathodon beds” of Mobile 
y, regarded as fossil beds by Lyell, are beyond doubt accumulations 
made by the aborigines of the country. They are often in heaps and 
contain ashes, burnt shells and charcoal, and bear no evidence of accu- 
mulation by wave action. The Report of Prof. Mallet, as Chemist of the 
Survey, contains analyses of a large number of rocks and ores.

1859, pp. 48.—Collectors of mineral and geological specimens will be 
to know that Dr. Krantz has published an American edition of his 
h 
hited States. This Catalogue will serve an excellent purpose in guiding 
Mineralogists and others as to the comparative value of mine and 
‘ological specimens, and at the same time it gives an idea of the ex- 
tended scale upon which Dr. Krantz conducts business in his justly cele-
