AN OPTICAL ILLUSION.
Standing at the corner of a ward robe with a plate-glass door in such a way that only one-half of the body projects from the side, the other half is seen in the glass, and at a little distance it will appear as if the whole body of the person ca'n be seem while in reality half of it is hidden behind the wardrobe, as indicated by the
dotted lines in the sketch. By raising the one visible arm the looker-on imagines that the arm in the glass Is also raised. There is nothing remarkable about that, however, says the PostrDlspatch, but when one leg is lifted the Impression is as if the lad performing the little feat had suddenly Jumped in mid-air and was hanging suspended there by some invisible mechanism* With the necessary paraphanalia—a paper fool’s cap, etc. —the whole will look like a jumpingjack operated by a‘string.
