On the 16th February 1875 a very successful Conyersazione and 
Exhibition was held in the Picture Gallery of the Mechanics’ Insti- 
tute, and was attended by a very large number of friends. 
In addition to the course of Geological excursions already 
noticed, a very successful one was made in July 1874, into Upper 
Wharfdale, Grassington being the starting-point of the ramble. 
A Microscopical Section was formed in 1874 in connection with 
the Society. It numbered 22 members and held eight fortnightly 
meetings on Wednesday evenings. It was however found that the 
Society was not strong enough to carry on fortnightly meetings of a 
Section concurrently with the weekly meetings of the whole Society, 
and the Section was consequently discontinued. Mr. J. Abbott was 
president and Mr. Frederick Haigh secretary of the Microscopical 
Section during the time of its existence. Much good work was 
done in connection with it, and at three of its meetings the following 
papers were read:—
