them to a pursuit far more satisfactory than some 

 which previously occupied much of their leisure. 



A list of books upon the scientific side of the sub- 

 ject will be given to enable the amateur to pursue 

 his study with more accuracy and more efficient 

 apparatus than are contemplated for beginners with 

 limited purses and scanty leisure. 



I am aware that some of the methods recom- 

 mended are contrary to the practice of scientists, 

 but I am not writing for experts in possession of 

 high-class apparatus, but for beginners, and I do 

 claim that an amateur with simple apparatus may 

 produce results which, though not perfect, are good 

 and acceptable for nearly all purposes. A doctor, 

 for example, who may wish to photograph certain 

 specimens of only temporary interest, is enabled 

 to do so by simple means perhaps already at com- 

 mand, and with sufficient exactitude to serve his 

 purpose, even with high powers, whilst with low 

 powers he need not be ashamed of comparing results 

 with the best. WALTER BAGSHAW.
