Sliding Objective Changers. 



This apparatus is so arranged that the observer may centre each separate objective, and it admits of 

 the use of an unlimited number of objectives. 



The tube slide, as illustrated, is screwed on the end of the body like an Qrdinary revolving nosepiece, and may 

 be secured with the slide action either pointing to the front or turned sideways. 



The plane of the tube is inclined to the axis of the tube at an angle of about 84. The plane of the objective 

 slide, is inclined at a corresponding angle, so that, on being withdrawn, the objective moves slightly away from the 

 specimen.
