magnification of only ten diameters. Then he transferred the minute fragments of glass to a slide, and, having arranged the lantern as a microscope-lamp, commenced his examination.
"Ha!" he exclaimed presently. "The plot thickens. There is too much glass and yet too little; that is to say, there are only one or two fragments here that belong to the spectacles; not nearly enough to complete the building up of the lenses. The remainder consists of a soft, uneven, moulded glass, easily distinguished from the clear, hard optical glass. These foreign fragments are all curved, as if they had formed part of a cylinder, and are, I should say, portions of a wine-glass or tumbler."
