Microscope

Description
This is a compound monocular with coarse and fine focus, inclination joint, circular stage, sub-stage iris diaphragm, sub-stage mirror, tri-leg base, and a Zeiss objective. The inscriptions read “John W. Sidle & Co. Lancaster, Pa. ACME” and “176” and “G. S. Woolman / AGT / N.Y.” John W. Sidle began making microscopes in Philadelphia in 1879, and moved to Lancaster in 1880. George S. Woolman, a microscope merchant in New York, was his agent for a brief period around 1880.
Sidle developed the Acme stand in conjunction with James Edwards Smith, a professor of medicine and active microscopist. Sidle described this example, an Acme No. 3, as “a good, cheap stand, which would be adapted to all kinds of work.”
