Mr. Stiles then gave a lecture on lantern slides in which he fully explained the method of producing them from the original negative, and furnished details of exposure, development, clearing, and where requisite, toning.
The remainder of the evening was spent in exhibiting, with the limelight lantern, a collection of about fifty slides prepared by the lecturer, and embracing views of Scotland, the lake district, the Isle of Man, the neighbourhood of Doncaster, and of Furness Abbey.
