Of course the artist will spurn this quick method of repro- 

 duction; but, as opposed to many of the painful attempts of 

 some of our entomolgists who do not possess the divine gift, it 

 will be found that this method is calculated to give infinitely 

 more pleasure to those who must look at the finished work. 



In the accompanying plate specimens are shown from the 

 most delicately transparent to the most opaque wings obtainable 

 and yet all, except perhaps fig. 10, give practically all the vena- 

 tion details necessary for taxonomic purposes. It will be noted 

 that none of the figures has been retouched in the least. 



This method can be and undoubtedly has been applied to the 

 making of prints from such objects as skeletonized leaves, thin 

 rock sections, bone sections, handwriting, and manufactured 

 articles such as laces, woven fabrics, etc.
