(4) Photomicrography. 
Messrs. B,. and J. Beck's Vertical Photomicrographic Camera. — 
This simple form of photomicrographic camera is intended for use with 
the Microscope in a vertical position, and for several kinds of work it 
is exceedingly convenient. 
The Microscope is easily adjusted and does not require any special 
attachment to the fine-adjustment. The camera is raised or lowered by

uprights. The apparatus is exceedingly rigid, the base being heavily
