The cover is then pressed gently down on the ring of cement so that contact is complete all the way round, and, after placing the slide on the turntable once more, a fresh ring of cement is apphed partly on the edge of the cover and partly on the slide. When thus prepared the dry mount is completed and should be labelled on the left-hand end of the slide, the nature of the specimen, the treatment to which it has been subjected, the mounting medium, and the date being indicated.
