"Improved" Huxley-Type Dissecting Microscope
The brass Huxley-type dissecting microscope can function both as a simple or compound microscope by using one or multiple objective lenses. The instrument stands on a tripod base, with two of the curved legs angled and the rear leg standing vertical. The circular stage is made from glass and is painted black. The substage mirror is connected to the rear leg and is set in a gimbal. The arm is connected to a column which extends from the rear leg via a rack and pinion mechanism. The thumbscrew connects to the rear leg controls the coarse focusing by moving the arm closer or further from the stage. The objective lens sits in a circular cut out of the arm, directly above the stage. The microscope has a wooden chest-style case with a lower interior drawer, which holds the accessories. The case is secured by a lock and push mechanism. -

Botanical "School" Microscope
The botanical entomological microscope consists of a brass tubular pillar stand that screws into the lid of the wooden case. At the top of the pillar is a fixed arm that holds the three stacking objectives that can be used together or individually. The round black stage with slide clips elevates up and down the pillar manually simply by lifting it up and down the pillar as desired. The gimbaled sub-stage mirror is attached to the lower pillar. The design was often called a "School Microscope" because it could be used for educational purposes such as particular examination of botanical specimens, small insects or insect parts, water fleas and other objects that could be readily collected and examined. This instrument is an English import and follows the design of the Society of Arts School Microscope of the 1855 time period. The design is similar to the earlier model of the Ellis Aquatic microscopes. It was also considered an inexpensive, simple microscope and became a popular model. The wooden case is secured by two swinging brass hooks. -
