    chemical nature of the calculus itself, I wrote to Mr. Crosse con- cerning it, and forwarded the calculi for his examination. To that gentleman and his son I am indebted for having put together the several pieces, so as to build up the calculus as it existed in the urethra, and from which a few casts have been prepared by Mr. Charles Goodwin, of Norwich.* The entire stone is four inches and seven-eighths in length, and considerably larger at one end than at the other. The larger extremity had been situated posteriorly in the prostatic part of the iirethra. Around the broadest part it measures four inches and five-eighths, from which it tapers to the other extremity, where it measm'es one inch and five-eighths in circumference. Midway between the two ends it measures three inches and a half. It is rounded and convex on the lower surface, or that which was neai-est to the perinseum, which is the aspect respresented in the plate; and the opposite surface is somewhat flattened and concave. It presents two curves,—a larger one, the concavity of which is in the centre of the upper surface of the stone, and apparently corresponding with the curved shape of the posterior part of the urethra, and a smaller one in the opposite direction, near the anterior extremity. The surface is intersected with numerous angular Hnes, indicating the division of the stone into many pieces, which are well shown in the plate. In order to give some idea of the difficulty in fitting together the several pieces constituting this calculus, I cannot do better than transcribe part of a note from Mr. Crosse, dated April 7, 1844. You will be surprised to learn that my son put together nineteen portions of the calculus sent me, and that by two hours attention last night I adjusted the other eight, so that I have made out a most singular specimen, shaped like the outline herewith sent, nearly five inches long. There is one vacancy which answers to the large portion you sent to Dr. Golding Bird, and the anterior flat end shows a deficiency, which I can readily supply in imagination, as shown by the dotted line, and to which the fragments you name undoubtedly answer. The portions are now fixed together lightly by gum; and I hope to be able to make * Possessed of the mould I shall be happy to prepare a cast for any gentleman who may wish to have one.
