184 PROCEEDINGS OF THE SOCIETY. 



had the ditches and ponds open to him, and there was the opportunity for 

 all to add to their physiological knowledge of this interesting and beautiful 

 gi-oup. 



Mr. J. May all, jun., gave a very interesting account of a recent visit 

 to Jena, which he said Mr. Crisp had aptly termed the " Mecca of micro- 

 scopists." There he had been afforded every facility for examining all the 

 processes of manufacture as carried on in the factories of Dr. Zeiss. He 

 also described his interviews with Prof. Abbe and the way in which they 

 had together tested numerous objectives which he had taken with him for 

 comparison. (A full description will be printed post.) 



The President said he thought the Fellows would agree that their 

 Society was sufficiently mature to be entitled to get the highest possible 

 perfection obtainable with respect to its aj)paratus and appliances, so that 

 whatever would contribute to the attainment of any increase in this per- 

 fection could not fail to be of the greatest interest to them. From what 

 they had just heard, he felt sure that Mr. Mayall's visit to Jena had not 

 been in vain ; his communications would no doubt give rise to an amount 

 of interest and attention which would be certain to bear fruit at no distant 

 date, in the form of still further increase in the perfection of the very 

 admirable work which they were already so familiar with.
