2013.3.60Description
These are a few of the many objects in the Transylvania collection. Each specimen of plant or animal is preserved in Canada Balsam between plates of glass and then these are put in hardwood frames. They then were used for projection by means of a cal-oxyhydrogen microscope, which in reality was a type of magic lantern using "limelight."
There are twenty-three sliders with unvarnished wooden frames made with mitered corners. The outside dimensions of these measures 151 x 56 mm. The identifying legend is written on the frame in India ink. There is no name of maker for this series.
The larger series of 72 sliders was made by W. & S. Jones, 30 Holborn, London. These are the sliders illustrated. The wooden frames, usually of varnished mahogany, measure 185 x 62 mm. The central openings which contain the specimen vary in size and shape depending on the size and shape of the specimen. Several (11) of the sliders have been crudely cut down in recent years, presumably for the purpose of projecting them in a modern micro-projector. The fate of the eleven slides emphasizes the necessity of separating old from contemporary apparatus.Collection
