Description

The instrument is made of brass copper alloy. The pillar has a rectangular cross section and the manufacturer's name engraved on one side. Rack work cut into one edge allows the stage mounting to be moved up and down, by a mill-edged knob, for focusing. The stage is secured by a single screw. It consists of a ring attached to a bar with a pinhole for accessories and two screws holding a circular leaf spring. The mirror is mounted in a pinhole below the stage. An arm screwed to the top of the pillar carries a ring with an internal thread, into which objectives can be screwed. The Gould body tube has an eyepiece with two lenses in a blackened eyecup, a field lens and at its lower end an external thread to take objectives. Objective lenses can be singly, combined or in with the body tube. The lower end of the pillar can screw into a socket in the front edge of the box or a circular brass base. The box is mahogany lined with blue velvet.

The accessories are four objectives, one with no threads that fits into the settings of the others, copper alloy forceps, stage forceps, a steel pin and a scalpel on ivory handles, a glass and wax wet cell, a live box and a copper alloy ring to hold it on the stage, two ivory sliders and a lens in a copper alloy setting on a steel pin that fits horizontally into a copper alloy post. The post can be mounted in the socket on the box or the circular base.
