III. On a Photographic Printing Process. By Captain 

 Tripe, 12th Eegt. N. I. 



[This paper which was read at the Meeting of the Photographic Society, has 

 been received from the Secretary to that Society, for publication in the 

 Journal.] 



Bangalore, 22nd September, 1856. 

 Gentlemen, — I have much pleasure in laying before you this 

 paper which Dr. Scott will read to you. There is a value in the 

 Printing process, that I am about to describe which, coupled with 

 the fact, that I do not obtrude on you uninvited, will acquit me of 

 presumption in doing so. 



My facilities for acquiring experience in this branch of the art, 

 have been great, and there are few, to whom this will be read, who 

 have the requisite leisure, to practice the various proeesses,fromtime 

 to time put forward, and so decide for themselves, which would be 

 the simplest, as to manipulation, the safest, as to permanence, and 

 the best, and most certain, as to results. I have followed many 

 methods — and, keeping in mind all their several advantages, I have 

 no hesitation in recommending for your use, though it is by no 

 means, the simplest in manipulation, a Process published by Mr. 

 Sutton of Jersey, in which Hyposulphite of Gold is used as a 

 toning agent. The Council of the Society are, I believe, about to 

 notify the opening of an Exhibition to be held at Madras during 

 February next, and, as it is only through successful Printing, that 

 the Photographer's skill is properly represented, this may be no 

 inappropriate occasion to bring to your notice a process, not as yet 

 generally followed, but which will show itself superior, it is to be 

 hoped, over " Old Hypo" at the forthcoming Exhibition. 



Thin French negative Paper, albumenized, is what I find best 

 for my purpose. To albumenize, use 

 10 oz. Albumen, 

 20 oz. Dist. Water,
