PROCEEDINGS OF THE SOCIETY. 
Prof. Bell said tlieir thanks were due to Mr. Rousselet for this com- 
munication, and he felt sure that all would sympathize with him in being 
again unable to read it, remembering that it was similarly edged out at 
their last meeting. 
Prof. Bell reminded the Fellows of the Society that after Wednes- 
day the 28th inst., the Library would not be open on Wednesday 
evenings until after the vacation. Also that the rooms would be entirely 
closed from the 14th August until the 11th September. With regard 
to the opening of the Library on Wednesday evenings, he had caused a 
return to be prepared showing the attendance, so that they might see to 
what extent the arrangement had been appreciated. From this return it 
appeared that during the first quarter the total attendance was thirteen, 
and that there were four nights on which nobody came. From April 5th 
to June 7th the number who came was also thirteen, none being present 
on three nights. During the whole period the greatest number in attend- 
ance on any evening was four, whilst the average was rather less than 
one and a half. He thought if these statistics were reported and 
published with their Proceedings perhaps the Fellows might understand 
more clearly what success the arrangement had met with. 
The next Ordinary Meeting of the Society would take place on 
October 18th.
