One other sign, the imprint of the naked foot, is to be noted, found only once on this slab. Two human footprints are traced on one of the pillars of the crypt of the Petit-Mont in Arzon. They are said to be divided off, by a slight relief, from the rest of the granite frame on which they are sculptured, and which contains other drawings. Similar figures, engraved on rock or on tombstones, are cited from abroad, in lands far apart. In Sweden, the prints of naked or sandaled feet are common among the rock sculptures of the age of bronze which represent the curious scenes of the life of the people of that period. It is proper to note that these Scandinavian and Morbihan sculptures are not synchronous; the idea of an immediate influence of one people on the other can not be entertained. One might, however, maintain the identity of origin. The other inscriptions of Brittany are enigmatic in every respect. But they probably had a conventional value, a determined meaning. There is first of all a sort of complicated cartouche, plainly defined, having the appearance of a buckler or heraldic shield. Among the isolated signs it is proper to note a figure of the shape of the letter U with the ends spread wide apart and curved in opposite directions. It recalls, with some aid from the imagination, the character which on the Scandinavian rocks represents more plainly ships and barks. The sculpturing of hands and feet is to be remarked in connection with similar characters on the rocks in America, many illustrations of which appear in the present work. B. Souché (_a_) in 1879 described and illustrated curious characters on the walls of the crypt of the tumulus of Lisières (Deux-Sèvres), France, some of which in execution markedly resemble several found in the United States and figured in this work. SPAIN. Mr. T. Jagor (_a_) communicated a brochure in reference to the Cueva de Altamira, transmitted to him by Prof. Vilanova in Madrid: “Short notes on some prehistoric objects of the province of Santander,” in which Don Marcelino de Sautuola describes the wall pictures and other finds in the cave discovered by him at Altamira. Mr. Jagor remarks as follows on the subject:
