There is, at any rate, no doubt about them.

Yet, rather more than half a century ago, when the Abbe Boucher de Perthes found palaeoliths in the gravels of the Somme at Abbeville, and was the first to recognize them for what they are, there was no small scandal.

Now-a-days, however, the world takes it as a matter of course that those lumpish, discoloured, and much-rolled stones, shaped something like a pear, which come from the high terraces deposited by the Ancient Thames, were once upon a time the weapons or tools of somebody who had plenty of muscle in his arm.
Plenty of skill he had in his fingers, too; for to chip a flint-pebble along both faces, till it takes a more or less symmetrical and standard shape, is not so easy as it sounds.

Hammer away yourself at such a pebble, and see what a mess you make of it.

To go back for one moment to the subject of eoliths, we may fairly argue that experimental forms still ruder than the much-trimmed palaeoliths of the early river-drift must exist somewhere, whether Mr.Harrison's eoliths are to be classed amongst them or not.
