AUTHOE'S INTRODUCTION 



CHARLES KINGSLEY has said, <I have 

 ^^ seen the cultivated man craving for 

 travel, and for success in life, pent up in the 

 drudgery of London work, and yet keeping his 

 spirit calm, and perhaps his morals all the 

 more righteous, by spending over his micro- 

 scope evenings which would too probably have 

 been gradually wasted at the theatre.' 



This is strong testimony to the value of the 

 microscope alone as an entertaining and civilising 

 instrument. But the value of the instrument is 

 increased enormously by the addition of the 

 photographic camera. It is not at all necessary 

 to have a huge camera like that represented in 

 the illustration (Fig. 8). But of this we shall 

 say something later.
