2. The seconddivision of the Stone age is characterized by the Moustier 

 spear-head. (See Figs. 3, 4, and 5.) This iustrnnient, which was at- 

 tached to the end of a long lance, diflers little in contour from the Saint 

 Acheul ax — is somewhat more pointed, but is distiuguished by having 

 only one of its sides shaped. The other was made at one blow which 

 split it from the adjacent stone, and was never retouched. It is there- 

 fore not biconvex, like the preceding, but plano-convex, and conse- 

 quently only half as thick.
