content: The Universal microscope that Bausch & Lomb introduced 1884 was similar to the popular Investigator but larger and heavier and equipped with several new features. The basic stand with case cost $55; with two objectives and camera lucida it cost $80. This example is of that sort. It is a compound monocular with coarse and fine focus, large circular stage, inclination joint, sub-stage condenser and iris diaphragm, sub-stage mirror, and tri-leg base. The inscription on the arm reads “PAT. OCT. 3 1876 / PAT. Oct. 13, 1885.” The inscriptions on the stage read “Bausch & Lomb Optical Co.” and “HENRY KAHN SAN FRANCISCO” (this refers to the dealer). There is an bracket at the bottom that we do not understand.
