Newer Magnesian, or Conglomerate Limestone. Synonyme, 
First Floetz Limestone of Werner.—This is the oldest rock 
of the supermedial order. It is distinct fromthe older rocks 
of similar composition, associated with the mountain lime- 
stone, though sometimes blended with them. It hasa gran- 
ular, sandy structure, a glimmering lustre, and a yellow col- 
our ; andis associated with conglomerate limestone The 
organic remains are not numerous: but they may serve to 
distinguish it from the older formations. They consist of 
fish, shells, &c. 
In giving the foreign localities of the Red Marle and 
Newer Magnesian Limestone series, we perceive the Ger- 
man fetid limestone, cellular limestone, compact marly 
limestone, and bituminous marle slate, to be included near 
the centre : rocks, whose relative position has long per- 
plexed geologists. Reference is of course made to all 
other countries, where rocksalt, or gypsum occurs ; since, 
in every known locality, these minerals, certainly the 
latter, are accompanied by the red marle, or as it is some- 
times » the saliferous sandstone. North America is 
among these references ; as Louisiana, the banks of Hock- 
hocking, Sciota, Wabash, Tenessee, Kanaway, Great San- 
dy, &c. and the Salines, near Unondaga and Seneca Jakes, 
in New York. We have seen a specimen of the rock from 
which the salt springs issue at the latter locality, and have 
no doubt itis the red marle; and we are informed, that the 
2 ae lies above this rock, and the coal beneath it. It 
will be of great importance to American geology, to 
this rock identified with the English red marle; as it will 
furnish a convenient starting point, from which geologists 
may proceed to identify other strata above and beneath. 
Should the New York rock and the English rock prove to 
ler basins will be easily determined. We shall expect to 
find this point settled by Mr. Eaton, in the Geological Sur- 
vey of the rn canal, he is now prosecuting,
