LABORATORY MICROSCOPES 



[CH. II 



Fig. 85. Watson & Sous, Edinburgh Students' Microscope (Stand G). This 

 is a good representative of the tripod-base, English models of to-day. It is in gen- 

 eral like the Powell and Lea/and stands which have held their position with the 

 foremost English microscopists for the last 40 years. (See Carpenter-Dallinger, 

 p. 172. ) 



Microscopes with tripod base something after this pattern are now being 

 made on the Continent. 



Attention is called to the sub-stage for the condenser . It possesses centering 

 screws so that any apparatus used in it may be accurately centered. It is to be 

 hoped that all microscopes of this grade will soon be supplied with a centering 

 sub-stage.
