carrot, and shaving off very thin slices 
with a razor. The razor must be shar^) 
and should be kept well moistened with a 
little water, to which a small quantity of 
alcohol has been added. The thin slices, 
or sections, as they are called, are floated 
off into a basin of water, whence they are 
lifted out, placed on a slide, covered with

thin glass and examined under the micro- 
scope. The openings from the interior of 
the leaf to the outer air through the 
stomata will then be readily seen. 
In cutting these sections the leaf and its 
supporting carrot may be held in the 
hand, but this requires a good deal of 
dexterity. The easiest way is to fix the 
whole in a section cutter as it is called. 
Section cutters are kept for sale by most 
dealers in microscopes, but a home-made 
one, which will do very good work, is 
easily made, and some day we will tell our 
readers how to make one.
