t one way and then the other at right angles. Be sure that all the paper is covered. Dry in a dark room, pinning the paper to the wall or some smooth surface. After two or three times trying one can apply the solution evenly. The prints are very beautiful, and if well washed do not fade. ANSWERS TO SEVERAL CORRESPONDENTS.--We have had many queries as to how one may become a member of the Camera Club. Any member of the Round Table may become a member of the club by sending his or her name to the Round Table. We hope all of our readers who own cameras will join the club, as we expect to give some new and original plans for work during the year. SIR KNIGHT B. P. ATKINSON, Tilton, New Hampshire, asks, 1. What is Eikonogen made from, and what is the chemical name. 2. What is the difference between chrome alum and alum crystals. 3. When we expect to have another photographic contest. 4. Is Watkin's exposure meter a reliable machine. 5. How can films be kept from curling. 1. Eikonogen is the sodium salt compounded from three different chemicals, and comes in whitish-gray crystals. It is the name of a developing agent patented by Dr. Andreson about six years ago. It is not poisonous, does not stain the fingers, and gives a clear negative with plenty of detail. 2. The difference between chrome alum and alum crystals is principally that chrome alum has twice the strength of alum crystals, being a double salt, instead of the commercial alum usually sold. Both chrome alum and alum crystals are used for the same purpose in photography, for clearing and hardening the film of the negative. 3. The date has not yet been fixed for our next photographic contest, but we intend to have another soon. 4. It is out of our province to pass judgment on any kind of photographic apparatus. 5. Films may be kept from curling by soaking them after they have been developed and before they have been dried, in a solution of glycerine, 1/2 oz., distilled water, 16 oz., for five minutes, and then drying as usual.
