 photomicrography, the main point in which was its great stability. The 

 Microscope was built on the well-known Wales model, and had been made 

 to his specification by Messrs. Swift and Son. The body-tube, stage, 

 and snb-stage were all carried on one substantial casting, ensuring the 

 utmost rigidity of all the movements. The mechanical stage had 

 considerable range in each direction, allowing very large objects to be 

 examined, and could be removed. The draw-tube was racked, and had 

 more than sufficient range for use with long or short tube objectives. 

 Altogether it seemed to him to be an extremely useful type of stand, 

 suitable for high-power work of the most critical nature, and so well 

 balanced as to be equally stable either in a vertical, inclined, or horizontal
