Compound Microscope in Case by Carpenter & Westley, London, 19th Century

The cylindrical pillar screws into the square wooden base. The limb is carried on the top of the pillar by a compass joint. Two struts on the pillar are attached to a sliding collar on the limb that tightens to hold the inclination. A plano-concave mirror is set in a horseshoe mount at the lower end of the limb. Below it a milled screw raises a square sectioned bar from within the limb, for focusing (.1). The body tube is engraved with the manufacturer's name, eyepieces are pushed into place at the top of the tube whilst a screwthread circles the tube's bottom end (.2).

The instrument is stored in a mahogany case with a domed lid. Case has fitted, velvet lined supports for microscope and accessories (.18). The accessories are three eyepieces (.3), four objectives (.4), a specimen chamber (.5), an erecting tube in a can (.6), a Lieberkühn in a can (.7), a spring stage (.8), an empty copper alloy can (.9), three copper alloy fittings consisting of two washers and one knob (.10), stage forceps (.11), thirteen wooden sliders consisting of eight sets of glass specimens and five opaque sliders (.12), a nose-piece bracket for attaching body tube to pillar (.13), a leather box with embossed star decoration (.14), two lens caps with different sized apertures (.15), card box containing one micro circle (.16), a wooden base with screwthread, into which base of pillar can be attached (.17).
