enclosure between the microscope ocular and the film. With color 

 filters and color-sensitive emulsions, c()nsideraV)le flexihility can be 

 had in photographic records for the emphasis of important details 

 and the suppression of others. The greater the knowledge of both 

 microscopy and photography the better will be the records; of the 

 two a knowledge of microscopy is more important since the usual 

 principles of photography apply {7,10).
