Prehistoric Human Remains in Mexico.—Mariano de la Barcena describes in the "American Naturalist" some human remains that have been found in the hill Peñon de los Baños, near the city of Mexico, imbedded in a hard rock of silicified calcareous tufa. The cranium, with the upper and lower maxillæ and fragments of the collar-bone, vertebræ, ribs, and bones from the upper and lower limbs, are exposed, and present a yellowish appearance and the characteristic aspects of fossilization. No other fossils occur in the hill, and the age of the formation can only be estimated. The bed has evidently suffered upheaval since the bones were deposited in it, and their disordered condition is accounted for by this fact. Two facts seem at once to show that, even supposing it to be of the present age, it must be of remote antiquity. They are, the elevation of the ground above the actual level of Lake Tezcuco, and the remarkable hardness of the rock, which is different from that of the other calcareous rocks that contain remains of ceramics or roots of plants clearly modern. The stratigraphical and lithological characteristics of the ground indicate that the formation belongs to the Upper Quaternary, or at least to the base of the present geological age.
