310 PROJECTION MICROSCOPES ON THE MARKET [Cn. IX FIG. 175. MODEL 4-5 DELINEASCOPE WITH THE MICROSCOPE IN A VERTICAL POSITION FOR HORIZONTAL OBJECTS. (Cut loaned by the Spencer Lens Co.). This figure is to show the course of the rays for lantern slides in a vertical position and for microscopic objects in a horizontal position. A mirror M reflects the light vertically through the horizontal specimen, and by means of a prism (PR) in the tube of the microscope the vertical light is made to extend out horizontally to the screen. A joint in the microscope frame makes it possible to turn the microscope down in front of the instrument after turning the lantern-slide objective aside on its hinge. Then vertical objects can be projected in the usual manner, or by using the prism (PR) the image can be reflected down upon a horizontal drawing surface.
