THE MICEOSCOPE. 



By ANDREW BOSS. Fully Illustrated. With notes chiefly Bibliographic. 



This is the celebrated article contributed by Andrew Boss to the 

 " Penny Cyclopedia," and quoted so frequently by writers on the Micro- 

 scope. Carpenter, in the last edition, of his work on the Microscope, and 

 Brooke in his treatise on Natural Philosophy, both refer to this article as 

 the best source for full and clear information in regard to the principles 

 upon which the modern achromatic Microscope is constructed. It should 

 be in the library of every person to whom the Microscope is more than a 

 toy. It is written in simple language, free from abstruse technicalities.
