  "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.

  Pocket Microscope

  The simple brass microscope stands on a circular base. The base also acts as the stage and has a circular cut out which allows a specimen to be observed. The pocket microscope would have been used in the field due to its small size. The circular lens holder stands over the base/stage and there are two small columns that connect them.

  Microscope Lamp

  The lamp is made from brass and cast iron. The instrument stands on a cast iron circular stand which is painted black. The circular column is connected to the base and holds the lamp via an arm. The lamps height can be adjusted by loosening the thumbscrew and adjusting the height along the column. The glass and brass reservoir is connected to the burner and has a blue glass chimney with a white porcelain shade which is removable. The shade is held by a circular attachment which stands adjacent to the column and can be adjusted vertically by a thumbscrew located at the bottom of the arm.
