The vertical illuminators are two in number, separately mounted in tubes which may be each in turn swung in place by moving a lever; one tube carries a prism, the other a plane glass disk. In the illustration the prism is shown in place; since the horizontal displacement of the prism (P in Fig. 45) must vary with each objective, Reichert has provided an ingeni- ous method of indicati
