While this American-made microscope mounts on a round iron and wood base which was made for it, it is possible, given its small size and the fact that the stage is removable, that it was originally case-mounted and served as a field microscope. |
This advertisement appeared in the Army Surgeon's Manual for use of Medical Officers, Cadets, Chaplains, and Hospital Stewards by William Grace published in 1864 .
