INTRODUCTORY.

Preliminary Remarks on the Subjects treated of in this Work.
Definition of the Terms Recent and Pleistocene.
Tabular View of the entire Series of Fossiliferous Strata.

No subject has lately excited more curiosity and general interest
among geologists and the public than the question of the Antiquity
of the Human Race--whether or no we have sufficient evidence in
caves, or in the superficial deposits commonly called drift or
"diluvium," to prove the former co-existence of man with certain
extinct mammalia. For the last half-century the occasional
