“ The misery of the systematist has already made itself apparent in synonyms for a well-known class of monuments—namely, the dolmens. To make the matter more perplexing, structures of quite a different form, and possibly intended for a different purpose, are called by the same name. A dolmen, generally speaking, consists of an arrangement of stones, few or many in number, supporting one or more stones in such a way as to inclose a cavity beneath. These supporting stones may form the four walls of a chamber, which may or may not be covered by a mound of earth. ”
