stage. In its early construction it was heavily built 

 and of a thickness which would make it unsuitable for 

 use with modern substage accessories.

mechanical parts are attached to and form an integral 

 part of the stage. The Attachable Stage, Fig. 28, is 

 complete in itself, being attachable to the microscope, 

 and may be removed at will. Both are provided with 

 graduations, usually divisions in millimeters, in both 

 directions by which one may read off the amount of 

 space which is covered and locate the position of an 

 object for future reference.
