Mcintosh projection microscope Lyman D. McIntosh, Chicago (unsigned). Pat. March 13, 1883. Microscope for a Solar and Stereopticon Combination, c. 1885

The Mcintosh Galvanic Company of Chicago, have a large exhibit of their manufactures, including Dr. Mcintosh's projection microscope. The accompanying cuts give an idea of the arrangement of parts, and of the appearance of the instrument when arranged as an ordinary stand. Dr. Mcintosh has spent most of the winter in New Orleans and has had a place fitted up in the space occupied by his exhibit in which to show his instrument. I spent a pleasant hour with him, and came away with an impression that the resources and adaptability of projection were not fully comprehended as yet by microscopists. For the making of drawings it is greatly to be preferred to the camera lucida in any form, while for continuous study of a preparation it has a double advantage in giving a larger field than can be viewed with the eve-piece, and being much less wearisome to the eyes.
