Film Quickly Developed.

Sixty rolls of photographic film handled in ten minutes’ actual working time is the claim made for a system of glazed stoneware developing tanks now on the market, according to Popular Mechanics Magazine. The tanks are sold in sets of three, one for developing, one for fixing and one for washing. Each has a concave bottom, terminating in a brass drain cock. The last, or washing, tank is fitted also with an overflow connection, to permit continuous water circulation from bottom to top.
