Note 1 — Chapter VIII · Tombs.

The true name of this cave is the Betche aux Roches. A very excellent essay on the subject was read by the explorers, MM. de Puydt and Lohest, in August, 1886, to the Historic Society of Belgium, and “Les Fouilles de Spy,” by Dr. Collignon, published in the Revue d’Anthropologie, 1887, may also be consulted. Excavations were also carried on in the same cave in 1879 by M. Bucquoy (Bul. Soc. Anth. de Belgique, 1887). He distinguished five ossiferous levels and picked up some flints of the Moustérien type, and even some Chelléen hatchets, to which he gave the name of coups de poing.—Fraipont and Lohest; “Recherches sur les Ossements Humains Decouvertes dans les Dépôts Quaternaires d’un grotte à Spy.”
