This compound monocular suitable for student use has coarse and fine focus, trunnion, square mechanical stage, Lister limb with support for sub-stage mirror, and Y-shaped base. The “Baker / 244 High Holborn / LONDON 1” inscription on the base refers to Charles Baker, a prolific instrument maker who began in business in 1851.
This may have been used by John Bernard Smith (1858-1912), a lawyer who, in 1884, became an assistant to J. V. Riley, entomologist at the U.S.D.A. Smith became Prof. of Entomology at Rutgers College and entomologist at the New Jersey Agricultural College Experiment Station, in 1889. He was known especially for his work with mosquito eradication.
