 in the Chair. 



The thanks of the members were voted to the donors of the 

 books upon the tables. 



The President referred to the death of Mr. R. D. 

 Darbishire, who for many years took an active part in the 

 proceedings of the Society. Mr. Darbishire joined the Society 

 in 1853, served on the Council from 1869 to 1S85, and was 

 elected President in 1886. Mr. Darbishire's services to the 

 Society, like his services to the community at large, were long- 

 continued, disinterested, and carefully considered : but great as 

 those services were, all who knew Mr. Darbishire were aware 

 that his personality was even greater than his works.
