Educational Microscope Compendium, c. 1865
This is an interesting example of Highley's
Educational Microscope Compendium. c. 1865. Two microscopes are
stored within the main case. One being Highley's Educational
Microscope having the coarse focus utilizing a fusee chain drive.
The other microscope is a case-mounted
aquarium microscope.The optical components are interchangeable
between each of these two instruments. The remaining section in the
storage case houses some slide making tools and slides.
In How to Work with the Microscope,
lectures by Lionel Smith Beale-1861, it is implied that some
microscopes designed and/or sold by Samuel Highley were manufactured
by William Ladd, London. Ladd first introduced the use of a fusee
chain focusing mechanism for microscopes in 1851. Samuel Highley
(1826-1900) was a London-based instrument maker, publisher, and
photographer active from the mid 19th century.
Illustration from the British Medical Journal 1867
