THE LIVING ANIMALS OF THE WORLD 



their ways with which books of exploration and travel, school treatises and current 

 terature are nowadays crowded. Without such help, indeed, the study of zoology 

 would be practically impossible, and therefore pictures have always been considered 

 necessary to books of natural history. Too often, however, they have been sorry treatises 

 upon the reality, reflecting the imaginations of the draughtsman rather than the truth of 



nature. 



Photography was therefore welcomed by naturalists and scientific writers as a means 



of vastly needed improvement, yet only recently has it been possible to utilise it in any 



important picturesque way 

 in the illustration of living 

 animals. For a long time 

 the difficulties to be over- 

 come baffled both photog- 

 raphers and naturalists. The 

 makers of photographic in- 

 struments and materials were 

 compelled to experiment for 

 many years before they were 

 able to perfect " quick " 

 plates and lenses that would 

 answer the purpose, and then 

 it was only here and there 

 that a man was able or will- 

 ing, or had the opportunity 

 to make use of the portable 

 cameras, telephoto lenses, and 

 other special apparatus re- 

 quired to obtain successful 

 portraits of living creatures, 

 especially those at liberty 

 " on their native heath." 



It must be remembered, 

 too, that the processes of 

 mechanical engraving had to 

 be perfected in order to re- 

 produce such photographs so 

 that they might be printed 

 without the intervention of 

 brush or graving-tool, with
