Dr. Edw. G. Love also exhibited twenty-five photomicrographs, 

 mainly of crystals and vegetable tissues, taken by polarized light. 

 Dr. Love stated that he had made many negatives with the use 

 of polarized light ; that it frequently brings out details which 

 cannot be discerned by ordinary light ; and that the method 

 was well adapted to vegetable structures, such as starch-grains, 

 wood-sections, &c. The subject was also discussed by Messrs. 

 Dean, Cox and Dr. Skeeh
