MICROSCOPE SLIDES PRESERVED AND 
LANTERN SLIDES DRY MATERIAL 
Make your teaching effective by ordering slides which really illustrate the 
facts you want to bring out. Nowhere will you find a wider range of prepared slides 
and material put up by trained technicians. 
The microscope slides range from the lowest Algae, through the Fungi, Lichens, 
Liverworts, Mosses, Ferns and the Flowering Plans, including many of the rarer as 
well as the common forms. Special attention is paid to life-histories, vascular 
anatomy and soine features of ecology. 
Practically all of the lantern slides are from original negatives, not from text 
books. They show native wild flowers and trees, tropical and south hemisphere 
plants and many photomicrographs.
