536 PROCEEDINGS OF THE SOCIETY. 



Mr. Shillington Scales, in reply to the President, said he had been 

 studying the drawing, but found it incomprehensible without explanatory 

 notes. 



Mr. C. L. Curties said he should like to defer giving an opinion on 

 it until it had been made ; but, as far as he could understand the drawing, 

 it would be a very costly arrangement, and he did not think anyone 

 could give an opinion on it without seeing it when made. 



The President thought that, as in the case of Mr. Nelson's apparatus, 

 it was open to any Fellow of the Society to make it. 



The President said he should like to propose a vote of thanks to 

 Messrs. Baker for the loan of the Microscopes to illustrate the subject of 

 his paper. Also to the writers of the other papers and communications 

 and demonstrations. 



This was put to the Meeting and carried unanimously. 



It was announced that the next Meeting of the Society would take 

 place on October 19, and that the rooms of the Society would be closed 

 from August 12 until September 12.
