The other specimen(5227) while Early Paleolithic throughout the mostof the exposed surface, was chipped by Xeolithic manalong the upper edge, as evinced by the fresh fracturesurfaces. The Early Paleolithic weather-crust, orpatina, has somewhat less thickness than seen in thelast, and consists, not of a gloss, but of an alterationin color to a dirty white. The dark spots seen on theEarly Ialeolithic Mirface are caused by limonite de-posits. Plate XI shows a collection of artifacts of recentdate, collected bv Mr. P>rower in the vallev of Mill.
