Vitamin B Terminology

Abstract

Place a drop of the mounting medium in the center of a large cover-glass, and orient the objects in the medium. Cover the mount with a smaller cover-glass, and over this place a large drop of fluid Canada balsam. Cover gently with a slide until the smaller cover-glass and the mount are surrounded by a ring of balsam and the balsam also covers the exposed under surface of the large cover-glass. The slide is then inverted, revealing the microscopic mount under the one cover-glass and surrounded by a protected balsam seal.
