Report of Society's Meetings. 151 
Mr. Matthey said that the fact that the juice remaining 
in the megass became weaker and less sweet than what 
was extracted by the mill did not affe6t the accuracy of 
the estimate he had made of the extra yield of sugar 
likely to be obtained by diffusion, because his estimate 
was based upon the recovery of dry sugar at a certain 
fraction of the total sugar, which he estimated at 14 per 
cent. He exhibited under the microscope several longi- 
tudinal and traverse sections of sugar-canes, showing 
their cellular tissue. 
The Campbell Memorial. — Mr. Imlach then brought 
forward the motion of which he gave notice, as recorded, 
at the previous meeting. 
This, being seconded by Mr. Sherlock was unani- 
mously adopted. A subscription list was thereupon 
opened, and the members present subscribed over 
$200. 
Evening Meetings,- — The President's proposal to hold 
monthly evening meetings for the benefit of those who 
could not attend the ordinary afternoon meetings was 
then taken up. He thought evening meetings would be 
very useful to young men in the city and suburbs, who 
would thus have a place to go to, once a month to read 
and discuss papers, which would lead to their mutual 
and literary improvement. 
Mr. Sherlock seconded the resolution, which was 
adopted. 
The President said that it would be a sine qua non 
that all papers must first be submitted to the Directors, 
and that any paper pertaining to politics or religion 
would be absolutely excluded. The Directors would de- 
cide when the meetings should be held.
