This photo-micrographic apparatus is also available when it is desired to photograph gross specimens as, for example, embryos, insects, etc., by reflected light, as is represented in the figure on p. 86. The photographic objective of 64 mm focal distance, is best adapted to this purpose. It fits in a collar in the neck of the camera and yields a magnified image of about 3 diameters. The object is brought into proper focus by means of a small stand, the table of which may be raised or lowered as required. Price of the apparatus without microscope stand =40.--= 106. =Small stand for supporting specimens= to be photographed by reflected light as mentioned above =4.75= 107. =Welsbach lamp= with reflector =6.--= 108. =Illuminating lens= of 100 mm diam. on stand =12.--= 109. =Photo-micrographic apparatus=, for use in horizontal and vertical position. It is in construction similar to the foregoing, but is provided with joint for inclination and clamping lever, and can be used at any angle. Large size bellows and plateholder, for plates up to 24×24 cm. Moveable platform with three leveling screws and clamping-bar for holding stand. Price of the apparatus, with 2 simple plate-holders, ground and plain glass plate, etc., without microscope stand =60.--= [Illustration: Photo-micrographic Apparatus No. 109.] =Edinger's Projection Apparatus.= [Illustration: Edinger's Projection Apparatus with Nieser's Photographic Camera.] 110. =Edinger's Projection Apparatus=--For projecting and drawing large objects slightly magnified. (Cf. Zeitschrift für wissensch. Mikroskopie. VIII. 1891.) A polished wooden base, in which a lime wood drawing tablet is inlaid, supports a wooden stand which in turn holds a horizontal metal tube in which are a collecting lens and a reflecting mirror. The upright also carries, two arms, by rack and pinion adjustment, the one supporting the object stage, the other regulating the length of the camera. On the other side of the upright is a support for a lamp. The rays of this lamp are converged by the collecting lens upon the mirror, are reflected downward to the object and through the objective to the drawing board below. The various adjustments permit considerable variation of magnification with the same objective. Price, including lamp =18.--= For photographic purposes this same apparatus may be had with Nieser's photographic camera, plate holders, focussing plate etc. 111. =Edinger's Projection Apparatus with Camera= for plates 9×12 cm and 13×18 cm =38.--=
