Beck Microscopes. 
This catalogue first deals with the simplest forms of compound 
microscopes and proceeds through the various types of more 
elaborate instruments up to the most complete research micro- 
scopes, and binocular microscopes in all forms are then described. 
Particulars and prices of microscopic apparatus and accessories 
are given after which micro-projectors are dealt with. A complete 
range of magnifiers and reading glasses completes the catalogue. 
For convenience all microscope outfits are shown with prices 
of the stand and apparatus given separately, so that with any 
change in the outfit the alteration in price can be at once 
determined.
