Distilled Water 4 oz. Sulphate of Iron 80 grs. Sulphuric Acid 4 scruples. Have this solution made up at the dealer in photographic supplies, as the sulphuric acid is a dangerous acid to handle. The small quantity in the solution will do no harm, though it is best to use rubber fingertips when handling all known poisonous chemicals. Place the print in this fixing solution for 30 seconds, pass it through three or four changes of water, and dry by the fire. Landscapes printed on green tinted paper make a pleasing change from the brown and black tones generally used. SIR KNIGHT W. F. BLATCHLEY asks what kind of sensitized paper to use for pictures which are to be reproduced in periodicals. Any printing paper, with the exception of blue prints, may be used; but the black and white tones are preferred to the reddish browns. SIR KNIGHT LE ROY THOMPSON asks what other color beside red and violet may be produced with nitrate of uranium. Green, blue-black, chestnut-brown, copper color, and several other tints may be made by different toning solutions or treatments of the print. The processes will be described in early numbers of the ROUND TABLE. SIR KNIGHT THOMAS S. WINSTON, Box 65, Albertville, La., says that he has some curios, consisting of turtle shells, water moss, water celery, wild boar's tusks, etc., and a collection of about one thousand stamps, which he would like to exchange for a Pocket Kodak or a Kombi Camera. SIR KNIGHT LAWRENCE FRALEY sends the following formula for developing bromide paper: Water (filtered), 20 oz.; carbonate of soda, 300 grs.; sulphite of soda, 500 grs.; hydrochinon, 30 grs.; metol, 30 grs. Sir Knight Lawrence says that he has used this developer, and finds that one can make a much shorter exposure and obtain clear whites and fine detail in shadows. This developer works equally well with dry plates. Sir Lawrence has the thanks of the club for his formula. LESLEY ASHBURNER asks what makes prints gray; the sizes and prices of transferrotype and bromide paper; a formula for toning solution; and in what number it gives directions for enlargements. The reason prints assume a gray color is because they are left too long in the toning solution, or the toning solution is not fresh. Bromide and transferrotype paper may be bought in any size desired; 4 by 5 costs 50 cents per dozen, and 5 by 7 costs 65 cents per dozen for both papers. A formula for toning solution may be found in No. 825. A formula for toning solution comes with every package of sensitive paper, and may always be relied on to produce good results. Several toning solutions will be given in an early number of the Camera Club. The number giving directions for enlarging is No. 801 of the ROUND TABLE, and the article is entitled "Bromide Enlargements."
