Reichert's New Movable Mechanical Object-stage. t — C. Reichert 

 describes the above auxiliary, which is represented in figs. 68 and 69. It 

 is completely independent of the form of the Microscope-stage and can 

 be fitted to every Microscope, as it is applicable both to rectangular 

 stages of at least 70 mm. breadth and to circular stages of 90-130 mm.

diameter. The auxiliary is secured to the Microscope-stage by a single 

 screw S as is shown in fig. 6<s, in which TT represents the stage-plate. 

 The under-side of the object-stage is made out of a strongly secured 

 cast-iron bar to prevent Ijending, and contains the screw-nut. The end 

 of the screw-spindle is enlarged into a knob L, which presses against 

 the under-side of the Microscope-stage. Resistance to the screw-action
