Microscope

Description
This is a compound monocular with push-pull focus and micrometer screw, trunnion, sub-stage diaphragm, Lister limb with sub-stage mirror, black base, and wooden box. The “J. W. QUEEN. PHILA / 186” inscription suggests that it was made in the 1850s, before the firm became James W. Queen & Co. Queen was still offering instruments of this sort in the 1870s.
Queen termed this “Dr. Woodward’s Student’s Microscope,” noting that it was the “most satisfactory microscope ever offered to the student.” It was identical to Queen’s Table microscope but had a micrometer adjustment for focus. The lenses are achromatic.
This was probably designed in conjunction with J. J. (Joseph Janvier) Woodward, a young physician who had received his degree from University of Pennsylvania in 1853, and then gave private lessons in microscopy. Woodward became an assistant surgeon with the Union Army in 1861.
