[Spencer Lens Co. | This stage is convenient for use with the projection microscope as it can be attached to any square stage and has a great range of motion. This large range is especially necessary for series of'organs or embryos. For the projection microscope it would be better to have both milled heads for moving the stage on the side as in the next. § 414. Stage for Specimens.—This should be large and prefer- ably square or oblong. The central opening should be 50 to 60 mm. in diameter, and have a large iris to lessen this diameter at will. The specimen stage should be on an independent support and adapted for independent motion. This is necessary so that all objects capable of projection may be used on the stage and moved far enough from the.
