By HENRY SCHERREN, F.Z.S., 



Author of ' Ponds and Rock Pools, 1 etc. 



Profusely Illustrated. Crown 8vo. Cloth gilt. 2s. 



'The object of this book is to show what an immense deal lies just beyond the 

 perception of the naked eye, waiting to be revealed by the application of the simplest 

 and cheapest forms of magnifier. The author explains what a mistake it is to sup- 

 pose, as so many beginners in scientific observation do, that a costly compound 

 microscope, with a host of accessories, is necessary to pry into any except the most 

 recondite mysteries of nature ; and he reminds the young student how much of 

 Darwin's most fruitful labour was transacted by the aid of simple lenses. A book 

 which can be confidently recommended.' Pall Mall Gazette. 



1 We cannot imagine a more useful preliminary training for a young student than 

 working with a pocket lens through the course indicated by the author. Field.

 boy or girl, will find abundant food for mind and recreation for many a year to
