diameter, easily carried in the pocket, being. fully equal to a

Professor William A. Rogers, who was personally ac 
quainted with Mr. Tolles made a brief andress, in which he al- 
luded to the great amount of painstaking work Mr. Tolles was 
able to accomplish. He kept up the struggle for existence to a 
remarkable degree. Mr. Rogers said the society’s duty is to 
erect a fitting monument to the memory of Mr. Tolles, in Mt. 
Auburn. 
Dr. H. J. Detmers, of Champaign, Illinois, spoke earnestly 
of the business integrity of Mr. Tolles and of the excellence of 
his work, especially the objectives which yet stand unsurpassed. 
He urged that the members of the society should contribute lib- 
erally toward erecting a monument to the memory of the great 
optical manufacturer. President Cox suggested that a sub- 
scription paper be circulated before the meeting adjourn. 
Professor Smith said he had known Mr. Tolles while he was 
at Spencer’s, in Canastota. He believed that the association 
should show its appreciation of Mr. Tolles in some other man- 
ner than circulating a subscription list. He suggested that a 
committee be appointed to ascertain the amount that should be 
expended and that the association be assessed for whatever 
amount shall thus be reported. There was a considerable dis- 
cussion about the manner of the testimonial, resulting in the 
adoption of a resolution that Professor Rogers, Dr. Detmers and 
Dr. Blackham act as a committee to report the best method of 
showing the association’s respect for the deceased Mr. Tolles. 
The same committe was authorized to take action regarding 
Chas. A. Spencer.
