=The Indian Idea of the "Midmost Self."=--In attempting to explain the significance of a pentagonal stone dodecahedron with vestiges of figures on it found near Marietta, Ohio, Dr. J. C. Morris assumed that, besides the Aryan idea of three dimensions of space, there is, to the Indian and to the Eastern mind, another--the fullness. "It is not the length and breadth and thickness of a cube, for instance, but the whole of it, which is as much to be considered as any one of its sides. A cube would therefore be represented numerically by seven, a dodecahedron by thirteen. Among the Mexicans the thirteen lunar months would thus correspond in the year with the twelve zodiacal signs and the earth which passed under and embraced them all." Again, the five digits came to be a measure of man's power or individuality, and thus a sacred number. A pentagonal dodecahedron, then, might be the emblem of the world; and the best time to be active in some contemplated pursuit might be shown by the zodiacal sign that came uppermost when the dodecahedron was thrown or rolled with appropriate ceremonies. As Mr. Frank H. Cushing interpreted the doctrine at the same meeting of the Anthropological Society, when the primitive man contemplates or considers himself or anything in its relation to space or the surrounding directions, "he notices that there is ever a front or face, a rear or back; two sides, or a right and a left; a head and a foot, or an above and a below; and that of and within all of these is himself or it; that the essence of all these aspects in anything is the thing itself--that is, the thing that contains their numbers or sum, yet is one by itself. This is indeed the very key to his conception of himself and of anything in relation to space and the universe or cosmos. He observes that there are as many regions in the world as there are aspects of himself or sides to any equally separate thing; that there are as many directions from him or his place in the world (which is his 'midmost' or place of attachment to the Earth-mother), or from anything in the world (which is its midmost or natural station), toward these corresponding regions. Hence to him a plane would be symbolized not by four, but by five--its four sides and directions thence, and its central self--as was actually the notion of the prairie tribes; a cube, not by six, but by seven, as was the notion of the valley Pueblos and Navajos; a dodecahedron, not by twelve, but by thirteen, as was the notion of the Zuñis, the Aztecs, and apparently--from this example--of the mound builders as well."
