APPENDIX B. 
APPARATUS AND REAGENTS. 
» Requisites for each Student. — Every member of the class should 
have : 
Two or three mounted needles. (Prepared by forcing fine needles, 
eye foremost, into round slender sticks, e.g., old penholders.) 
A sharp penknife or a scalpel. 
A pair of small steel forceps. 
A good magnifying glass ; Coddington lenses are excellent, but 
rather expensive. The ordinary tripod magnifier which costs at 
wholesale 30 or 40 cents will answer fairly well. 
A large note-book of unruled paper for drawing. 
A drawing pencil. 
‘A ruled note-book for record of experiments, ete. 
General Equipment of Apparatus. — Compound microscopes, as 
described in Appendix A. 
It is desirable to have one for the use of each member of the 
division. Usually it is not possible to secure nearly as many 
instruments as this. Much good work may be done with only 
one or two microscopes, but in this case the microscopical work 
will have to be done partly out of the regular class hour and part 
of it must be carried along while the class as a whole is doing other 
than microscopical work. 
A set of photomicrographs of some of the most important tissues 
described in the text, or of similar ones. 
Walmsley, Fuller, & Co., 134-136 Wabash Avenue, Chicago, will 
supply photomicrographs of botanical slides. Mr. W. H. Walmsley 
of this firm, who bears a national.reputation for such work, has 
undertaken to prepare a set of 24 negatives to illustrate the set of 
*1 An achromatic doublet, made by Leitz, superior to the Coddington lens, can be 
imported duty free for $2. It magnifies 8 times.
