RELICS OF MAN IN THE GLACIAL PERIOD. 263 



have been disturbed ; while others, still, denied altogether 

 the artificial character of the implements. 



At length, Dr. Regillout, an eminent physician resid- 

 ing at Amiens, about forty miles higher up the Somme 

 than Abbeville, visited Boucher de Perthes, and, upon see- 

 ing the similarity between the gravel terraces at Abbeville 

 and Amiens, returned home to look for similar implements 

 in the high-level gravel-pits at St. Acheul, a suburb of 

 Amiens. Almost immediately he discovered flint imple- 

 ments there of the same pattern with those at Abbeville, 

 and in undisturbed strata of the gravel terrace, where it 

 rested on the original chalk formation, at a height of 90 

 feet above the river. In the course of four years, Dr. Reg- 

 illout found several hundred of these implements, and in 

 1854 published an illustrated report upon the discoveries. 



Still the scientific world remained incredulous until 

 the years 1858 and 1859, when Dr. Falconer, Mr. Prest- 

 wich, Mr. John Evans, Mr. Flower, Sir Charles Lyell, of 

 England, and MM. Pouchet and Gauclry, of France, visit- 

 ed Abbeville and Amiens, and succeeded in making similar 

 discoveries for themselves. Additional discoveries at St. 

 Acheul have continued up to the present time whenever 

 excavations have gone on at the gravel-pits. Mr. Prest- 

 wich estimates that there is an implement to every cubic 

 metre of gravel, and says that he himself has brought away 

 at different times more than two hundred specimens, and 

 that the total number found in this one locality can hardly 

 be under four thousand. " The gravel-beds are on the 

 brow of a hill 97 feet above the river Somme," and besides 

 the relics of man contain numerous fluviatile and land 

 shells together with " teeth and bones of the mammoth, 

 rhinoceros, horse, reindeer, and red deer, but not of the 

 hippopotamus," * bones of the latter animal beiug found 

 here only in the gravels of the lower terraces, where they
