SPECIAL MICROSCOPIC SLIDES 
These slides are very valuable in indicating a wider range of structures than the previous sets. They will be 
found especially valuable to all teachers who are using or intend to use THE NATIONAL BIOLOGY NOTE¬ 
BOOK. To assist such teachers the numbers of the sheets in the note-book, in which slides are particularly useful, 
are indicated at the right.

We frequently have been requested to supply a series of slides particularly adapted to the requirements of schools 
which do not differentiate between the biological sciences. We offer, therefore, for those schools the following lists 
of slides selected as best adapted to a general biology course of Botany, Physiology and Zoology.

6038 SLIDE MAKING MATERIAL. Teachers of Biology oftentimes have considerable difficulty in 
assembling material for mounting on slides. We have arranged for a careful selection of 50 packages 
of materials, diatoms, pollens, seed spores, parts of plants, insects, hairs, etc., prepared especially 
for mounting. Pet set of 50 packages......................................................
