There are various forms of cover-glass holders, but only two types as far as the method of securing the cover glass is concerned. First, there are the bacteriological and the histological forceps (Fig. 45), which are self-closing. The two blades of such forceps must be forced apart by pressure in securing the cover glass. The second type of forceps is that in which the two blades are normally separated (Fig. 46), it being necessary to press the blades to either side of the cover glass in order to secure and hold it. There is a modification of this type of forceps which enables one to lock the blades by means of a sliding pin (Fig. 47), after the cover glass has been secured. It is well to accustom oneself to one type, for by so doing one may become dexterous in its use.
NEEDLES
Fig. 48.—Dissecting Needle
Two dissecting needles (Fig. 48) should form a part of the histologist’s mounting set. The handles may be of any material, but the needle should be of tempered steel and about two inches long.
