Thursday, January 11th, 1866, I read, at the South London Photographic Society, a paper on "Errors in Pictorial Backgrounds." As the paper, as well as the discussion thereon, is published _in extenso_ in the journals of the period, it is not necessary for me to repeat it here, but I may as well state briefly my reasons for reading the paper. At that time pictorial backgrounds and crowded accessories were greatly in use, and it was seldom, if ever, that the horizontal line of the painted background, and the horizontal line indicated by the position of the camera, coincided. Consequently the photographic pictures obtained under such conditions invariably exhibited this incongruity, and it was with the hope of removing these defects, or violations of art rules and optical laws, that I ventured to call attention to the subject and suggest a remedy. A little later, I wrote an article, "Notes on Pictures in the National Gallery," which was published in the _Photographic News_ of March 29th, in support of the arguments already adduced in my paper on "Errors in Pictorial Backgrounds," and I recommend every portrait photographer to study those pictures. February 13th I was elected a member of the Photographic Society of London. Quite a sensation was created in the Spring of this year by the introduction of what were termed "Magic Photographs." Some one was impudent enough to patent the process, although it was nothing but a resurrection of what was published in 1840 by Sir John Herschel, which consisted of bleaching an ordinary silver print to invisibility with bichloride of mercury, and restoring it by an application of hyposulphite of soda. I introduced another form of magic photograph, in various monochromatic colours, similar to Sir John Herschel's cyanotype, and I have several of these pictures in my possession now, both blue, purple, and red, dated 1866, as bright and beautiful as they were the day they were made. But the demand for these magic photographs was suddenly stopped by someone introducing indecent pictures. In all probability these objectionable pictures came from abroad, and the most scrupulous of the home producers suffered in consequence, as none of the purchasers could possibly know what would appear when the developer or redeveloper was applied. On June 14th Mr. F. W. Hart read a paper, and demonstrated before the South London Photographic Society, on his method of rendering silver prints permanent. "A consummation devoutly to be wished," but unfortunately some prints in my possession that were treated to a bath of his eliminator show unmistakable signs of fading. In my opinion, there is nothing so efficacious as warm water washing, and some prints that I toned, fixed, and washed myself over thirty years ago, are perfect.
