In all these investigations, interest has centered in the 

 reflected rather than in the refracted waves. The phenomena, 

 however, resulting from the transmission of light through 

 crystal plates are of great importance in practical microscopic 

 diagnosis and merit detailed consideration, from the standpoint 

 both of general theory and of observation. The present inves- 

 tigation was undertaken primarily to determine the influence
