“The spectacles were of a rather peculiar pattern. The frames were of the type invented by Mr. Stopford of Moorfields and known by his name. The right eyepiece was fitted with plain glass, as is usual in the case of a blind, or useless, eye. It was very much shattered, but its character was obvious. The glass of the left eye was much thicker and fortunately less damaged, so that I was able accurately to test its refraction.

“When I reached home, I laid the pieces of the spectacles together, measured the frames very carefully, tested the left eyeglass, and wrote down a full description such as would have been given by the surgeon to the spectacle-maker. Here it is, and I will ask you to note it carefully.
