borne, Alabama, and referred it to the age of the Loudon clay, of Eng- 

 land, and the Calcaire Grossier, of Paris. Having received L3'eirs Prin- 

 ciples, wherein the Tertlarj^ was subdivided into Eocene, Miocene and 

 Pliocene, he was enabled to class the Claiborne strata with the 

 Eocene. Tliis seems to have been the first application of the word 

 *' Eocene '" to American rocks, though as above remarked, Conrad had 

 compared American rocks with the London clay and Calcaire 

 Grossier, which were afterward made the tj'pe of the Eocene period.
