 in the room by Mr. Norman, who was invited to offer some remarks in 

 explanation. 



Mr. Norman said that the slides were examples of the Sanger- 

 Shepherd process of colour photography, as applied to medical photo- 

 micrography. A blow-through jet and zirconium lime were used for 

 the illumination of the specimens from which the negatives were made.
