 (2) that the former of these is the older ; (3) that the VaUey of the 

 Somme has been excavated to the depth of 40 or 50 feet since its 

 deposition ; (4) that both gravels contain bones of extinct animals, 

 and implements of human manufacture, the lower gravels, however, 

 containing the greater number of species of Mollusca,and the upper the 

 greater number of flint implements ; and (5) that the height (70 feet)
