The chief contributors to the exhibition of photographs were Messrs. Mayall, T. R. Williams, and Herbert Watkins in portraiture; and in landscapes, &c., Messrs. Francis Bedford, Rejlander, Rouch, Stephen Thompson, James Mudd, William Mayland, H. P. Robinson, and Breeze. By some carelessness or stupidity on the part of the attendants or constructors of the Exhibition, nearly all Mr. Breeze's beautiful exhibits--stereoscopes and stereoscopic transparencies--were destroyed by the fall of a skylight. Perhaps the best thing that the International Exhibition did for photography was the issue of the Jurors' Report, as it was prefaced with a brief History of Photography up to date, not perfectly correct regarding the Rev. J. B. Reade's labours, but otherwise good, the authorship of which I attribute to the late Dr. Diamond; but the awards--ah! well, awards never were quite satisfactory. Commendees thought they should have been medalists, and the latter thought something else. Thomas Ross, J. H. Dallmeyer, and Negretti and Zambra were the English recipients of medals, and Voightlander and Son and C. Dietzler received medals for their lenses. Early in 1862 the Harrison Globe Lens was attracting attention, and, as much was claimed for it both in width of angle and rapidity, I imported from New York a 5 by 4 and a whole-plate as samples. The 5 by 4 was an excellent lens, and embraced a much wider angle than any other lens known, and Mr. Hughes employed it to photograph the bridal bed and suite of apartments of the Prince and Princess of Wales at Osborne, Isle of Wight, and I feel certain that no other lens would have done the work so well. I have copies of the photograph by me now. They are circular pictures of five inches in diameter, and every article and decoration visible in the chambers are as sharp and crisp as possible. I showed the lens to Mr. Dallmeyer, and he thought he could make a better one; his Wide-Angle Rectilinear was the result. Mr. John Pouncy, of Dorchester, introduced his "patent process for permanent printing" this year, but it never made much headway. It was an oleagenous process, mixed with bichromate of potash, or bitumen of Judea, and always smelt of bad fat. I possessed examples at the time, but took no care of them, and no one else did in all probability; but it appeared to me to be the best means of transferring photographic impressions to wood blocks for the engraver's purpose. Thomas Sutton, B.A., published a book on Pouncy's process and carbon printing, but the process had inherent defects which were not overcome, so nothing could make it a success. Sutton's "History of Carbon Printing" was sufficiently interesting to attract both readers and buyers at the time.
