✦ Synopsis
This consists of a box about 25 centimetres long and of length and breadth to permit of the size of plate used. The apparatus as used takes a 3% x 4% plate. Supports at each short side of the box hold the ground glass and the sensitive plate which takes its place after the focus is adjusted. The box is carried on the draw tube by a snugly fitting opening. The apparatus is used vertically. It is to be noted, by the way, that in the section on illumination no mention is made of the condensed tungsten spiral lamps now available. The only incandescent bulb lamp mentioned in any detail is the pointolite. This is probably the best form, but its cost is a serious matter and for moderate powers.
as used for common animal and vegetable forms and rock sections, the cheaper lamps serve well.
It is gratifying to note that the metric system is generally used in the book and is specifically and emphatically endorsed. HENRY LEFFJIANN.
