PROCEEDINGS OF THE SOCIETY. 
names of the Fellows nominated at the last meeting of the Society were 
distributed in the room. He would ask Messrs. J. M. Allen and C. L. 
Curties to act as Scrutineers on that occasion. 
The President then read his Annual Address, in which he epitomised 
the history and work of the Society during the past year, concluding 
with an explanation of the practical construction of achromatic doublets 
and triplets, the formulas for which he illustrated by diagrams drawn 
upon the board. (The address will be printed in extenso.') 
Mr. A. D. Michael felt sure that everyone present would wish to join 
in returning a very hearty vote of thanks to Mr. Nelson for the address 
to which they had just had the pleasure of listening. With regard to 
the latter portion of the address it was perhaps hardly possible at the 
moment to fully appreciate its value, because of the difficulty felt by 
most persons in grasping lines of figures as they were read out, but 
there could be no doubt that when they had the matter before them in 
print, and it was possible to read it in full, they would find it to be a 
most valuable and instructive communication. That a portion of it 
should have to be passed over at the time was not at all an unusual 
occurrence, as many of the most valuable papers brought before the 
various learned societies were frequently taken as read for similar 
reasons ; but he believed he was right in saying that when this address 
was printed in extenso it would be a most valuable addition to their 
Journal, and would be of great assistance to all who desired to construct 
lenses upon correct principles. He had great pleasure in moving that 
the best thanks of the Society be given to the President for the address 
which he had delivered to them that evening. 
Mr. G. 0. Karop said it was his privilege to second this vote of 
thanks ; there could be no doubt that this address would be of inesti- 
mable value to many of those who were interested in the problems of 
optical construction. 
Mr. Michael said that as this motion was obviously one which could 
not be put from the chair, he had great pleasure in putting it, “ That 
this meeting returns its hearty thanks to the President for the address 
which they have just heard. 
Carried by acclamation. 
The President said that he must thank Mr. Michael for proposing, 
Mr. Karop for seconding, and the Fellows present for the very kind way 
in which they had received his address, and for the vote of thanks they 
had passed. It was always a pleasure to him to do what he could in the 
interest of the Royal Microscopical Society. 
The President announced that the Scrutineers had handed in their 
report, from which it appeared that all those gentlemen whose names 
were printed on the list had been duly elected. For his own part he 
could only again thank them for their renewed confidence, as shown by his 
election for a further term of office as President of the Society.
