The Chairman called upon Mr. Stiles (Hon. Sec.) to read a paper upon “Lantern Slides & how they are made”.

After a brief introduction in which he passed in review the various modes of making lantern slides, the lecturer showed by practical demonstration the method of making lantern slides by contact and by reduction in the camera, after which the plates exposed were developed by the aid of a hydroquinope developer. The plates used were Thomas’s new lantern plates, with which the lecturer had always had successful results. Processes for cleaning and toning the slides were then explained, and the lecture concluded with the exhibition of a number of slides (including some very fine photo-micrographs) by the aid of an Oxy-hydrogen lantern lent by the lecturer.
