LIST OF APPARATUS REQUIRED. 
A CompouND Microscope. An ordinary student’s micro- 
scope is quite sufficient. 
A DissecTING Microscope. A lens mounted on a stand 
with an arm, such as is used by engravers, answers 
very well. 
DissecTING TroucH. Nothing is better than a saucer, on 
on the bottom of which is placed a cirele of sheet cork 
three inches 1n diameter, fastened to a similar circle of 
sheet lead. 
DISSECTING INSTRUMENTS. Two knives, a pair of scissors, 
a pair of forceps, and two needles mounted in wooden 
handles. One of these needles should be straight, the 
other curved. A pair of nail scissors is necessary for 
cutting hard substances, which would spoil the finer 
pair. 
MISCELLANEOUS. Glass slides, three inches by one; and thin 
glass circles, three quarters of an inch in diameter ; in- 
sect pins, glass dipping tube, one or two watch glasses, 
blotting paper, a cork bung flattened on each side for 
fastening bivalve shells to, a pair of broad-pointed en- 
tomologist’s forceps, and a box lined with sheet cork, 
for insects. | 
For working by night the student will require in addition a 
MICROSCOPE LAMP, with a shade, and a 
BULL’S-EYE CONDENSER.
