PHOTOMICROGRAPHY AND ITS APPLICATION TO THE STUDY 



OF THE COCCIDAE. 



BY E. R. SASSCER.! 



In the discussion of this paper Mr. Schwarz inquired as to the 

 best method of mounting coccidae for photomicrographing. Mr. 

 Schwarz stated that glycerin mounts gave the best results, but 

 that since most of the material that he had to examine is mounted 

 in balsam he preferred that all be thus mounted. Mr. Baker 

 suggested that for purposes of reproduction the photomicrographs 

 should be retouched in order to bring out the important charac- 

 ters. To this Mr. Sasscer objected on the ground that this might 

 lead to the overlooking by others of the characters thus inten- 

 sified through their expecting to find them as conspicuous in the 

 specimen as in the published figure. The paper was further 

 briefly discussed by Messrs. Kotinsky, Ely, and Paine.
