Such may be cut with a razor, the stem being held between the finger and thumb of the left hand. The finger is held so that the blade of the razor rests upon it, while the stem to be dealt with is supported against a piece of pith or carrot placed between it and the thumb. The section is made with a diagonal cut of the razor. Some workers become very expert in hand-cutting, but I prefer to use a microtome. The least expensive form of microtome, which is quite good for botanical work, is represented in Fig. 25 ; it costs 5s., and consists of a tube surmounted by a round flange.
