others, to Tampico, and has deposited it in the collection of the New York Historical Society. Other stones, of a somewhat similar character, attracted his attention, but the most extraordinary sculpture he has described in his work is that to which he assigns the name of the American Sphynx. It is the image of a gigantic turtle, with the head of a man protruding boldly from beneath its carved and curving case. The back was correctly and artistically wrought, and all the lines of the scales were neatly cut in exact proportions. There were also in many parts fainter lines, shewing that the peculiar and graceful arabesques which are wrought by nature on the shell of this amphibious animal, had not been overlooked by the artist. This huge figure, raised on its four legs, was placed upon a large block of concrete sandstone. All its parts were equally true to nature. It was much mutilated, and the human head had been especially injured, but not sufficiently to obliterate the artistic workmanship with which it had been originally chiselled.
The place where Mr. Norman found these remains had evidently been the site of a large city; and, proceeding with his excavations among huge masses of earth or stones of every size and shape, he was, at length, rewarded by the discovery of another ancient figure. It was merely a human face, in full relief from the block, which was entirely cut away from the top and bottom, but left in two nearly circular projections at the sides. The ornaments on the head are peculiar, and are formed of three balls, with slight indentations, connected together by a band running across the top of the cerebrum and terminating at the sides just above the gigantic ears, which are nearly half the size of the face. The features and contour of the head are described as not resembling those of the American or Mexican Indian in any of their lines. This head is seventeen inches in length, twenty-one in width, including the ears, and ten in thickness. It was found on the side of a large pile of ruins, the remains of dilapidated walls, of which it had unquestionably formed one of the ornaments. It is to be regretted that Mr. Norman was unable to devote more time to the exploration of this region. His antiquarian
