business in Oxford Street, London. About this time Mr. Skaife introduced his ingenious pistolgraph, but it was rather in advance of the times, for the dry plates then in the market were not quite quick enough for "snap shots," though I have seen some fairly good pictures taken with the apparatus. At this period a fierce controversy was raging about lunar photography, but it was all unnecessary, as the moon had photographed herself under the guidance of Mr. Whipple, of Boston, U.S., as early as 1853, and all that was required to obtain a lunar picture was sufficient exposure. On December 3rd, 1861, Thomas Ross read a paper and exhibited a panoramic lens and camera at a meeting of the Photographic Society, and on the 15th October, 1889, I saw the same apparatus, in perfect condition, exhibited as a curiosity at the Photographic Society's Exhibition. No wonder the apparatus was in such good condition, for I should think it had never been used but once. The plates were 10 inches long, and curved like the crescent of a new moon. Cleaning board, dark slide, and printing-frame, were all curved. Fancy the expense and trouble attending the use of such an apparatus; I should think it had few buyers. Certainly I never sold one, and I never met with any person who had bought one. Amateurs have ever been the most restless and discontented disciples of the "Fathers of Photography," always craving for something new, and seeking to lessen their labours and increase their facilities, and to these causes we are chiefly indebted for the marvellous development and radical changes of photography. No sooner was the Daguerreotype process perfected than it was superseded by _wet_ collodion, and that was barely a workable process when it became the anxiety of every amateur to have a _dry_ collodion process, and multitudes of men were at work endeavouring to make, modify, or invent a means that would enable them to use the camera as a sort of sketch-book, and make their finished picture at home at their leisure. Hence the number of Dry Plate processes published about this period, and the controversies carried on by the many enthusiastic champions of the various methods. Beer was pitted against tea and coffee, honey against albumen, gin against gum, but none of them were equal to wet collodion. The International Exhibition of 1862 did little or nothing in the interests of photography. It is true there was a scattered and skied exhibition at the top of a high tower, but as there was no "lift," I suspect very few people went to see the exhibits. I certainly was not there more than once myself. Among the exhibitors of apparatus were the names of Messrs. McLean, Melhuish and Co., Murray and Heath, P. Meagher, T. Ottewill and Co., but there was nothing very remarkable among their exhibits. There was some very good workmanship, but the articles exhibited were not beyond the quality of the every-day manufacture of the best camera and apparatus makers.
