MICROPHOTOGRAPHIC APPARATUS 
The microphotographic apparatus (Fig. 29), as the name 
implies, is an apparatus constructed in such a manner that it 
may be attached to a microscope when we desire to photograph 
microscopic objects. It consists of a metal base and a polished 
metal pillar for holding the bellows, slide holder, ground-glass 
observation plate, and eye-piece. In making photographs, the 
small end of the bellows is attached to the ocular of the micro- 
Fic. 29.—Microphotographic Apparatus 
scope, the tocus adjusted, and the object or objects photo- 
graphed. More uniform results are obtained in making such 
photographs if an artificial light of an unvarying candle-power 
is used. 
There are obtainable more elaborate microphotographic 
apparatus than the one figured and described, but for most 
workers this one will prove highly satisfactory. It is possible, 
by inclining the tube of the microscope, to make good micro- 
photographs with an ordinary plate camera. This is accom- 
plished by removing the lens of the camera and attaching the 
bellows to the ocular, focusing, and photographing.
