MICROSCOPY: 



The Construction, Theory, and 

 Use of the Microscope.

NATURE says:- 



"From this point of view, let us hastec to urge every student of the microscope who wishes to

 Mr. Spitta's book witnout delay. It is a leisurely book— an unfriendly critic might even call it diffuse 

 —but there is scarcely a i:hapter which will not repay careful reading ; and when one comes to the 

 chapter on ' Testing Objectives,' one can but feel grateful to Mr. Spitta for his admirable treatment of 

 a diffit'jlt Kubiec'..'
