of stand-development, because the proportion of water is much larger. The water should be allowed to cool completely before use. It is convenient to keep a stock of boiled water in the stopped half-gallon bottles sold as " Winchester Quarts "; the bottles being filled quite up to the stopper.
Temperature is an important factor in stand-development, and when the dark-room is in a cold part of the house it is often convenient to bring the stand-bath into a warm room ; it being, of course, suitably protected against light. A carefully made case of sheet metal is a convenient protection.

Stereograph. Mr. S. Gill's Stereograph is an old but very useful device for occasionally obtaining a stereoscopic subject, with any camera and lens of half-plate size or larger, and this without any alteration to the camera (see Journal of the Photo-graphic Society, March 22nd, 1858, p. 186). Two pieces of good quality looking-glass, five or six inches square, are hinged to-gether so as to open and close like a book. This double mirror is now set up at a suitable distance from the camera (say about eighteen inches more or less as the case may be), so that each mirror reflects one aspect of the subject, and these aspects come into correct position on the ground glass. The adjustment is a little troublesome, but if several stereograms have to be made, a special stage or platform can be constructed. The same prin-ciple can be applied to the making of many small portraits on one plate, as in the case of the so-called stamp portraits.
StereoscopeI look at). This
instrument, which affords the best illustration of the nature of binocular vision, is largely dependent on photography for fur-nishing pictures possessing the required accuracy of drawing. A twin-lens camera is perhaps the most convenient for producing stereoscopic views, and is an essential when instantaneous pic-tures are required. For subjects which are not liable to move any camera may be used, the two elements of the stereogram being taken at a distance apart which may vary from a few
