Occurrence of Flint-implements in Gravel-beda. 293 



some specimens of the teeth of a horse — but whether recent or ex- 

 tinct the specimens were too imperfect to determine ; and part of 

 the tooth of an elephant {Elephas priimgeniusl). In the gravel-pit 

 of St. Roch, 1^ mile distant, and on a lower level, mammalian 

 remains are far more abundant, and include Elephas primige- 

 nius, Rhinoceros tichorhinus, Cervus somonensis, Bos priscus, and 

 Equus* ; but the workmen said that no worked flints were found 

 there, although they are mentioned by Dr. Rigollot.

 the outlines of two specimens are represented in the following dia- 

 gram. They are very rudely made, without any ground surface, 

 and were the work of a people probably unacquainted with the use 

 of metals. These implements are much rarer at Abbeville than at 

 Amiens, fig. 1 being the common form at the former, and fig. 2 at

the latter place. The author was not fortunate enough to find any 

 specimens himself; but from the experience of M. de Perthes, and 

 the evidence of the workmen, as well as from the condition of the 

 specimens themselves, he is fully satisfied of the correctness of that
