Torquay, evidences of man in the form of flint flakes and stone 

 implements, associated with the remains of Hyaena, Eeindeex', Cave- 

 bear, and the sabre-toothed Tiger or Lion (the Machcerodiis) , together 

 with the Mammoth and Ehinoceros. 



The truth of MoEnery's discoveries remained unverified until forty 

 years afterwards, whenPengelly's exploration of Kent's Cavern placed 

 the accuracy of McEnery's original observations beyond a doubt. 

 The stone implements sent up to Professor Buck] and eighty years 

 ago by McEnery seem to have disappeared, but the remains of 

 Macharodus and Hysena were preserved, and testify to the value 

 of his work as an original observer and discoverer of early Man.

A diagram is given by Mr, Eead (on p. 2) to show the evidence as 

 to the geological antiquity of the river-valley gravels containing the 

 flint implements in the valleys of the Somme, the Thames, and else- 

 where. Contrary to other geological evidence, based upon superposition 

 (where one would at once naturally conclude that the highest beds 

 were the newest, and the lowest the oldest), in these river- valley 

 deposits it is the oldest beds of gravel which occupy the highest 

 of the old river- valley terraces, and the newest gravels which lie 

 in the bottom of the present river valley. The explanation is so 

 obvious that (like the story of Columbus and the egg) everyone sees 

 it must be so, when told that the river in the course of centuries has 

 gradually deepened its valley, and that whereas it formerly flowed 

 perhaps hundreds of feet above its present level, it has, by its slow 

 erosive action (aided by rain, frost, and snow), cut its channel lower 

 and lower, until it has reached the depth at which we find it flowing 

 to-day. But the river, in wandering in its serpentine course along 

 its valley, leaves behind upon its flanks portions of its earlier and
