from the ordinary stage. This stage is intended for the Reichert model 
No. II., but it can also be fitted by means of the screw i to any larger 
stage of the Continental type. 
A Sliding Carriage and Stage for the Microscope f — Mr. G. W. 
Brown, jun., says, “The following description and drawing of plan 
and section of an improved sliding carriage and stage for the Microscope 
may be of interest. If put into actual use it will, I hope, bring as much 
comfort and satisfaction as it has brought to me. 
After considering the qualities useful in a good stage, Dr. Dallinger 
concludes J that an efficient substitute may be found for a mechanical 
stage in what he terms a 4 super-stage/ so arranged that the bearings 
shall be glass, and friction reduced to a minimum. He says that 
4 against its employment is the fact, first, that the slide is clipped into a 
rigid position ; and, second, that the aperture is too small to admit of 
the employment of the finger in moving the slide to assist in rapid 
focusing.’ He adds, 4 But these are defects which might certainly be 
overcome.’ 
The improved 4 super-stage ’ now described is believed to obviate 
these objections, and is not only 4 an efficient substitute ’ for a
