 ica. 



Am. Jour. Sci., (2) xviii, 193-200, 1854. 



Description of four classes of limestone, their geological position and 

 relation to other formations, and included minerals. The limestone of

 series; 2. The Green mountain series; 3. The White mountain series. 

 Their distinctive characteristics; tracing of the groups southward; 

 geological relations; position in time scale. Discussion of the " Taconic
