In the placer or alluvial deposits, the precious metal is found usually in a water-worn condition imbedded in earthy matter, and the method of working all such deposits is based on the disintegration of the earthy matter by the action of a stream of water, which washes away the lighter portions and leaves the denser gold.

While his edition was passing through the press, it was observed by the present writer that all the while the work had been in our hands in Greek, though in a slightly abbreviated form, as it had been imbedded as a speech in a religious novel written about the 6th century, and entitled "The Life of Barlaam and Josaphat."

For the protection of the impression, in the 12th and 13th centuries, when it was an ordinary custom to impress the seals on thick cakes of wax, the surrounding margin rising well above the field usually formed a suitable fender; at other times, as in the 14th and 15th centuries, a so-called wreath,1 or twisted shred of parchment, or plaited grass or reed, was imbedded in the wax round the impression.

About the same time P. C. Schmerling of Liege was exploring the ossiferous caverns of the valley of the Meuse, and satisfied himself that the men whose bones he found beneath the stalagmite floors, together with bones cut and flints shaped by human workmanship, had inhabited this Belgian district at the same time with the cave-bear and several other extinct animals whose bones were imbedded with them (Recherches sur les ossements fossiles decouverts dans les cavernes de la province de Liege (Liege, 1833-1834)).
