(Figs. 6r-66).—This instrument consists of an objective-like attachment which may be screwed into the nose-piece of the micro- scope. It bears on its lower end (Figs. 61-3) a small brush and the brush can be made more or less eccentric and can be rotated, thus making a larger or smaller circle. In using the marker the brush is dipped in colored shellac or other cement and when the part of the preparation to be marked is found and put exactly in the middle of the field the objective is turned aside and the marker turned into posi- tion. The brush is brought carefully in contact with the cover-glass and rotated. This will make a delicate ring of the colored cement around the object. Within this very small area the desired object can be easily found on any microscope. The brush of the marker should be cleaned with 95",, alcohol after it is used. (Proc. Amer. Micr.
