On March 14th, 1865, George Wharton Simpson, editor and proprietor of the _Photographic News_, read a paper at a meeting of the Photographic Society on a new printing process with collodio-chloride of silver on paper. Many beautiful examples were exhibited, but the method never became popular, chiefly on account of the troubles of toning with sulpho-cyanide of ammonium. The same or a similar process, substituting gelatine for collodion, is known and practised now under the name of Aristotype, but not very extensively, because of the same defects and difficulties attending the Simpsontype. Another new method of positive printing was introduced this year by Mr. John M. Burgess, of Norwich, which he called "Eburneum." It was not in reality a new mode of printing, but an ingenious application of the collodion transfer, or stripping process. The back of the collodion positive print was coated with a mixture of gelatine and oxide of zinc, and when dry stripped from the glass. The finished picture resembled a print on very fine ivory, and possessed both delicate half-tones and brilliant shadows. I possess some of them now, and they are as beautiful as they were at first, after a lapse of nearly quarter of a century. It was a very troublesome and tedious process, and I don't think many people practised it. Certainly I don't know any one that does so at the present time. This was the year of the Dublin International Exhibition. I went to see it and report thereon, and my opinions and criticisms of the photographic and other departments will be found and may be perused in "Contributions to Photographic Literature." On the whole, it was a very excellent exhibition, and I thoroughly enjoyed the trip. A new carbon process by M. Carey Lea was published this year. The ingredients were similar to those employed by Swan and others, but differently handled. No pigment was mixed with the gelatine before exposure, but it was rubbed on after exposure and washing, and with care any colour or number of colours might be applied, and so produce a polychromatic picture, but I don't know any one that ever did so. I think it could easily be applied to making photographic transfers to blocks for the use of wood engravers. December 5th, 1865, Mr. Walter Woodbury demonstrated and exhibited examples of the beautiful mechanical process that bears his name to the members of the Photographic Society. The process was not entirely photographic. The province of photography ceased on the production of the gelatine relief. All that followed was strictly mechanical. It is somewhat singular that a majority of the inventions and modifications of processes that were introduced this year related to carbon and permanency.
