ELEMENTARY PHOTO-MICROGRAPHY. 17 



the special branch of photo-micrography. To such 

 there is a fund of pleasure in store. As a fascinating 

 pursuit it has no equal. Independent of weather, 

 scenery, and sunshine, the photographer may be 

 seated at a comfortable fireside by gaslight and 

 produce pictures both marvellous and beautiful. 

 Every article at hand is capable of being pressed 

 into service, or if the operator dislike the prepara- 

 tion of his own objects, he has at command for a 

 small sum about 40,000 fine specimens of infinite 

 variety, which can be sent by post from the circu- 

 lating departments of Mr. C. Baker, and Messrs. 

 Watson and Sons, of Holborn, London. 



From his negatives the worker may make both 

 prints and lantern slides, and so provide a feast 

 of entertainment and instruction for himself and 

 his friends. 



But the beginner is warned against letting the 

 mere pursuit of pleasure keep him from the educa- 

 tional advantages of systematic work. Hence, 

 instead of making desultory efforts, he is strongly 

 advised to take some special subject and master 

 it before proceeding to another. For instance, he 

 may select plant life, beginning with the simple 

 cell, modes of cell growth, shapes of cells, cell 

 contents, and so following on to the various modi- 

 fications in highly-organised plants. Seeds, pollen, 

 flowers, and sections of stems are also interesting
