Collodion Vial.—Color-Boxes.
COLLODION VIALS. COLOR-BOXES.
This shaped vial is made expressly for collodion, to which purpose it is admirably adapted. It has a wide mouth, and is so constructed that the liquid flows clear and free. It is deep, and with a heavy protruding base, to prevent its falling. There are two sizes made at present, one to contain 2½ ounces—the other, 1½ ounce. I generally use the smaller ones, but always keep on hand, and would not be without, a few of the larger size.
