The stem of this chest microscope is fixed permanently to the bottom corner of its case connected by a joint that allows it to fold up or down or swivel to any orientation. By this means, the user can adjust the angle of inclination. Focusing is achieved by rack and pinion movement of the stage. The main tube has a double eye lens and a field lens. The microscope is supplied with a live-box, stage forceps, dissecting tools, a glass stage insert, an ivory and ebony stage insert, a number of ivory sliders, and an adjustment tool that tightens the inclination joint. The three objectives are housed in a rotating holder that allows a rapid change of the magnification. This microscope was sold by George Dollond. It was called by him a "Complete Pocket Microscope".
