The apparatus is now ready foruse. The use of a cylindrical litre measureheld by an assistant over the side of adish tilted on blocks has been suggested(see Fig. 270); but this is not a convenientarrangement, as it necessitates two personsworking together. Coating the The paper, cut to correct width, iswound tightly round the roller andthis is then inserted. The lower ves-sel having been placed upon blocksov-sr a small easily regulated flame andfilled with water, the emulsion is pouredinto the inner vessel to a height just suffi-cient to reach the roller and no paper is then pulled up tightly, andthe roller allowed to revolve over the12 surface of the solution, and in doing soreceives a layer on the paper. It is thenhung up, or if long, passed over rollers todry, and when dry is ready for use. Thetoning, fixing, and washing of these papersare dealt with in a separate section. Glos
