As has beenalready shown, the threeaxial planes of the sphereare at right angles toeach other, as, also, arethe axial planes of thecube and cylinder. (See Figs. 3, 3, 4.) So far as our knowledge goes no especial effortwas made in America to bring this inner similarityof the structure of the three externally differentforms, to the childs sense-perception, until Miss Glidden, of the Kindergarten Department ofPratt Institute, cut circles and squares of stiff paper,and by a most ingenious device made incisions inthem; by joining three circles together illustrated thethree axial planes of the sphere (see Fig. 3) ; and byjoining three squares illustrated the three axialplanes of the cube (see
