Photographing Insects under Magnification. 



In Camera Craft for October, 1914, there appeared an article by 

 Samuel B. Doten, Entomologist and Director of the Nevada Agricul- 

 tural Experiment Station, entitled, "A Cold Flame for Zoological 

 Work." 



Judging from the title, it is not suggestive of an article that would 

 interest entomologists, but it is, however, the results of experiments 

 conducted in the entomological field and is excellently illustrated by 

 half tones from photographs. These represent a few insects in their 

 natural attitudes, and well defined, especially aphids, photographed un- 

 der magnification illuminated by the intense light of fused silver wire. 

 The paper treats mainly of sources of proper lighting without heat 

 for photographing life under magnification. It is evident that such 

 illumination must not have a high temperature. Entomologists desir- 

 ing photographs of insects showing their natural attitudes will proba- 

 bly find Dr. Doten's methods of value. He promises further details 

 in the near future should his readers be interested sufficiently to ask 

 for them. E. T. C, JR.
