THE student should be provided with the following articles: 



A compound microscope with two eye-pieces and low and high

A simple dissecting microscope; a desirable form is an ordinary 

 watchmaker's lens provided with a support. An ordinary pocket- 

 lens; glass slides (3 X 1 in.), cover-glasses, watch-crystals, small 

 gummed labels, needles with adjustable handles, camelVhair

 insect-pins for pinning out dissected specimens, drawing materials, 

 and a large note-book for sketches and other records. 



Each table should be furnished with a set of small reagent-bottles, 

 a Bunsen burner, wash-bottle, test-tubes, beakers, and a bell-glass for 

 protection from dust. Thermometers, a balance, microtome, drying

REAGENTS AND TECHNICAL METHODS.f 



Alcohol. Since biological laboratories belonging to incorporated 

 institutions obtain alcohol duty free, it should if possible be liberally 



* Most of the apparatus and reagents here mentioned may be obtained from 

 any first-class dealer in physical and microscopical apparatus, e.g., from the 

 Educational Supply Co., 6 Hamilton Place, Boston, or James W. Queen & Co., 

 924 Chestnut Street, Philadelphia. Chemical apparatus may be obtained from 

 Eimer & Amend, 205-211 Third Avenue, N. Y. 



f Every laboratory should be supplied with some of the standard books upon 

 this subject, e.g., Strasburger's Botaniscke Practicum, Jena, 1884, and Whit-
