Description
Growing interest throughout the eighteenth century in natural history, and more particularly in pond-life, stimulated the development of the “Aquatic” microscope. This was initially designed by John Ellis (1710 - 1776) and is therefore often referred to as the “Ellis Aquatic”.

Ellis, a peripatetic naturalist, commissioned his first instrument in 1752 from John Cuff. It was designed to hold small samples of pond-water on a watch-glass stage. In this way the microscopic creatures contained in it could be observed. Several of these microscopes have dissecting tools as part of the kits and could also be used for microscopic dissection.
