Few strata have been more extensively worked than the superficial sands, clays, gravels, 
and brick-earth belonging to the Drift or Pleistocene series, and a great number of cave- 
deposits belonging to the same period have also been carefully explored ; nevertheless 
it is only in a few exceptional cases that the remains of man or of his works have been 
recorded as occurring in association with the mammalian and other organic remains so 
often found in such situations, and even these few exceptions have generally been viewed 
with doubt or else entii’ely rejected. The conclusion, in fact, that man did not exist 
until after the latest of our geological changes and until after the dying out of the great 
extinct mammals, had become almost a point of established belieff. Although resting 
mainly upon negative exidence and preconceived opinion, this prevalent belief was 
strengthened by the failure of the many ill-observed and dubious cases which had, from 
time to time, been brought forward. Owing to these circumstances there is little doubt 
that cases really meriting inquiry have been neglected or overlooked. To name only a 
few highly probable instances : — 
In 1833, Dr. SchmerlixgJ of Liege discovered in some caves in the valley of the 
Meuse, and at elevations of about 200 feet above the river, some bones of man 
associated with others of recent and extinct mammals: and he further subsequently

clusions, of the original paper. 
t Still the doctrine of the co-existence of man and of the great extinct pachyderms had been for some 
years partly accepted and taught by a few scientific men both in England and on the Continent.
