PROCEEDINGS OF THE SOCIETY. 487 



position of a diaphragm which cut off part of the light in the upper focal 

 plane of an objective filled with light, you might obtain somewhat 

 similar effects to those which occur when the light distribution in the 

 focal plane, due to the object, coincides more or less with that allowed to 

 pass through the diaphragm, to draw conclusions from this fact as to 

 the incorrectness of fundamental laws embodied in the Abbe theory was 

 an illogical procedure. 



Prof. Everett, being called upon by the President to reply, said that 

 no reply was needed. He had seen Mr. Rheinberg's experiment, and the 

 main feature of it was that the whole series of lines moved bodily across 

 the field, thus illustrating in a very interesting way the main point of 

 the paper. 



The President, in moving a hearty vote of thanks to Prof. Everett 

 for his paper, said it was quite clear that the subject was one which gave 

 opportunity for much fuller discussion than was possible at that Meeting. 



Mr. F. W. Millet's paper — the sixteenth of the series — ' On the 

 Recent Foraminifera of the Malay Archipelago,' was taken as read. 



Mr. F. Enock then gave an extremely interesting exhibition of lantern 

 slides photographed by the Sanger- Shepheard three-colour process from 

 living insects, which showed the specimens in their natural colours with 

 great brilliancy and fidelity. The advantages, and also the difficulties of 

 successfully producing perfect pictures from objects whose least move- 

 ment during either of the three exposures would spoil the set, were 

 explained, and a brief description of each slide was given as — owing to 

 the lateness of the hour — they were somewhat rapidly passed through the 

 lantern. 



The President was sure that all who were present must have been 

 delighted with this demonstration. Mr. Enock had broken fresh ground 

 in attempting to make these three-colour pictures of living subjects, and 

 it was quite clear that in this direction the process had a great feature 

 before it. They were extremely obliged to Mr. Enock for bringing these 

 beautiful pictures to show them. 



A hearty vote of thanks to Mr. Enock for his demonstration was 

 unanimously carried. 



The List of those gentlemen, eight in number, who were proposed 

 for election as Honorary Fellows of the Society at the preceding Meeting 

 was read, and, after a bollot had been taken, they were then declared all 

 duly elected. 



The President mentioned that he proposed to give a demonstration 

 of the microscopic structure of some Palaeozoic plants at the October 

 Meeting. 



Notice was given that the rooms of the Society would be closed from 

 August 15 to September 10, and the proceedings were adjourned to 

 October 19.
