This Table Stage, designed by Mr. G. T. West, and exhibited 

 by Messrs. Watson on May 19th, is intended to fit over the 

 stage of a microscope, when placed in a vertical position. 

 Obviously it will preserve the stage of a microscope, when 

 corrosive or other injurious fluids are used ; and when it is 

 heated it mil form a hot stage, the hands being protected by 

 the attached wooden blocks. It forms also a convenient dis- 

 secting microscope, when it is used in conjunction with a loup 

 holder. 



It is a thoroughly practical and useful adjunct for a micro- 

 scopist's outfit.
