Jones Most Improved type microscope by Cary – circa 1820

A rare larger style compound microscope by Cary. It is signed on the base, "Cary, London", and stands 10 " tall. Focus is with a single knob that moves the stage up and down. The design of the microscope seems to be a cross between elements of the Jones Most Improved and stylistic characteristics of the Cary Pocket microscope. The instrument has full aquatic movement in that the body tube can be moved forward, backward, and to either side. The limb attachment to the pillar by a compass joint, and folding tripod base is directly attributable to the Jones Most Improved, while the smaller scale of the instrument and conical base of the body tube is more in keeping with the Cary Pocket and Field types. The microscope comes with seven lenses: Five are numbered 1-5, and two are different sized lieberkuhns. The eyepiece is comprised of three elements and slips into the body tube. An auxiliary holder has a slip-out compartment that can accept any of the objectives from the lenses, thereby converting the compound instrument into a simple microscope. Other accessories include an ivory slider, two ivory dissecting tools, a brass tweezers, a stage forceps, and live box. The mirror is a single concave showing age wear along the edges, but otherwise in fine usable condition. The instrument is finished in lacquered brass. Most of the lacquer is missing from the body tube, and shows some age streaking and wear along the pillar, stage, and base. The instrument and accessories are housed in their own fitted mahogany case with brass escutcheon plate, figured top, and lock but no key. The case is in fine usable condition, noting an age crack along the middle of the top. The microscope is an important type by an innovative English maker from the early part of the 19th century.
