Fig. 51.—Turntable
Much time and energy may be saved by ringing slides on a turntable (Fig. 51). There is a flat surface upon which to rest the hand holding the brush with cement, and a revolving table upon which the slide to be ringed is held by means of two clips. In ringing slides, it is only necessary to revolve the table, and at the same time to transfer the cement to the edge of the cover glass from the brush held in the hand.
LABELING
There are many ways of labeling slides, but the best method is to place on the label the name of the specimen, the powder number, and the box, the tray or cabinet number. For example:
Powdered Arnica Flowers
No. 80—Box A—600.
