Per-sonally I use a piece of cotton, go all over the print as swiftlyas possible, and keep at it until everything is up and no streaksshow. Some prefer a brush, instead of the cotton. A most satisfactory formula for a hypo bath from the Brit-ish Journal of Photography which keeps clear and has suf-ficient acid and good hardening qualities is as follows: Hypo 16 oz. Metabisulphite Potash i^^ oz. Water 32 oz. This makes about a 50 per cent, solution. Diluted withequal parts of water is about right for plates, while one partto three of water is about correct for papers. 238. THE EVENING STAR. EDWIN LOKER. 239
