When comparative prints are made on bromide paper withthe manufacturers own amidol and metol-hydro. formulasand with duratol, the latter yields prints of superior gradation.In fact, I consider it the best bromide developer to date. Itworks perfectly clear on fresh paper without addition ofbromide solution, which would account for its yielding a fullerscale of gradation. For tank, the best dilution is one part of A, one part of B,and four parts of water. At 65 degrees, the time of develop-ment varies from sixteen to twenty-four minutes, accordingto the development speed of the plate and the contrast desired.I give the shortest time to such plates as the Wellington Anti-Screen and other ortho. plates of the same class on the Wat-kins card; eighteen minutes for films and average plates ofthe 180 and 250 Watkins groups; twenty-two minutes for the350 plates, and twenty-four minutes for the 500 plates. I alsomake an allowance of one minute for each degree over orunder 65. no
