Complete Microscope Outfits.
The outfits comprised in the following pages are made up with achromatic objectives, which suffice for all ordinary needs.
We are glad to supply any other combination of eye-pieces and objectives which may be preferred. The price of each outfit may be readily computed by adding together the cost of its various items.
Microscope stands, without objectives, will not be sold separately.
