ordinary way; whereas those whose household appurtenances include a clothes-wringing machine, with india-rubber rollers, may use these; or the bevelled edge of the cutting glass drawn carefully over the print with some pressure will do all that is required. For mounting prints in optical contact with glass the following method answers well: - Make a solution of gelatine (Nelson's X opaque), 20 grs. to every ounce of water, and whilst still warm immerse the print face downwards in it; place the glass in it, and after a few seconds bring them into intimate contact, and withdraw from solution, and squeegee thoroughly, and allow to dry. To mount prints which have an extremely glossy surface, like Aristotype, etc., when it is desired to retain the high gloss which cannot be done by mounting in the usual way, squeegee the print on to an old negative glass, cutting shape, or ferrotype plate, and when nearly dry coat the back with the mountant, and apply to the mount; use the squeegee vigorously, and when dry the glass may be stripped off, leaving the print upon the mount. (For the usual size of mounts, see Sizes, Photographic.)
Multiplying Camera. The most common arrangement for making a number of small negatives on one plate - as in the case of the so-called postage-stamp portraits - is to fit the camera with three or more miniature portrait lenses, and to so arrange the dark slide that several shifts are made; thus three lenses and four shifts will give twelve small negatives on one plate. Another arrangement is to use an ordinary camera, and in front of it support a number of small mirrors so adjusted that each reflects the sitter. In the stereograph we have an application of this principle. (See Stereograph.)
Muriatic Acid and Muriates. Muriatic acid is an old name for hydrochloric acid, and chlorides or hydrochlorates were called muriates.
Nameit Outfits. A set of reversed india-rubber type for stamp-ing titles on negatives. (See Titles on Prints.)
