"Acme" Class Microscope. — The "Acme" Microscope of Messrs. 

 Sidle and Co, (described in Vol. III. (1880) p. 523) is now adapted 

 for being readily converted into a Class Microscope (Fig. 29). This 



is accomplished by removing the metal tripod foot, and substituting 

 for it a wooden base of suitable form, carrying upon a jointed arm 

 a small lamp. It can then be handed round the class or lecture- 

 room. 



We think the ready conversion of ordinary students' stands into 

 class Microscopes, is a point deserving the attention of opticians.
