In it were a number of very small pieces of broken glass, some of which had been cemented together by their edges.
"These, I suppose," said I, looking with considerable curiosity at the little collection, "are the pieces of glass that we picked up in poor Blackmore's bedroom ?" "Yes.

You see that Polton has been endeavouring to reconstitute the object, whatever it was; but he has not been very successful, for the fragments were too small and irregular and the collection too incomplete.

However, here is a specimen, built up of six small pieces, which exhibits the general character of the object fairly well." He picked out the little irregularly shaped object and handed it to me; and I could not but admire the neatness with which Polton had joined the tiny fragments together.
I took the little "restoration," and, holding it up before my eyes, moved it to and fro as I looked through it at the window.
"It was not a lens," I pronounced eventually.
"No," Thorndyke agreed, "it was not a lens." "And so cannot have been a spectacle-glass.

But the surface was curved--one side convex and the other concave--and the little piece that remains of the original edge seems to have been ground to fit a bezel or frame.

I should say that these are portions of a watch-glass." "That is Polton's opinion," said Thorndyke, "and I think you are both wrong." "What do you say to the glass of a miniature or locket ?" "That is rather more probable, but it is not my view." "What do you think it is ?" I asked.
