  "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.

  Dollond Cuff-Type Microscope

  The cuff-style compound microscope is made from brass and is secured to a square mahogany base. The single-sided plano-concave mirror is mounted on a gimbal and connected to a brass mounting on the base which can rotate. The Bonnani stage is signed "Dollond London" and has a small removable bullseye condenser attachment. Beneath the stage are two stage clips which hold the specimen in place. The instrument comes with a removable spring-loaded attachment which slots into the circular cut out and acts as a method to hold a specimen in place. The stage is supported by a rectangular pillar, which is parallel to another movable pillar for coarse focusing. The movable pillar slides up and down, adjusting the body tube relative to the stage. The focusing is controlled by a Hevelius screw, with the top mount fixing the body tube in position, and the screw thread adjusts the position of the body tube along the pillar. The pillar has numbered markings which represent the position of the body tube from 1 to 6. The body tube sits in the arm attachment at the top of the pillar. The eye piece has a sliding brass protector. The instrument is housed in a pyramid-shaped mahogany case with an interior draw in the base. The case has a brass carrying handle and is secured by a lock, however, the key is not present with the instrument.

  Culpeper-style Compound Microscope

  The Culpeper-style microscope is made from brass and is attached to a mahogany base that contains a drawer. The design is based on instruments produced by Edmund Culpeper (1670-1737). The instrument stands on a decorative tripod stand which is connected to the fixed circular stage. Beneath the stage are two long stage clips which hold the specimens in place. The stage also has a spring-loaded attachment which can also be used to hold specimens in place for observation. The stage also comes with small forceps which connect to the stage by a pin. The sub-stage plano-concave mirror is attached to the base and is set in a gimbal which allows it to be rotated. Coarse focusing is achieved by rack work controlled by a thumbscrew on the body-tube. The body-tube stands directly above the stage which is held up by three curved pillars. The instrument is kept in its original pyramidal shaped mahogany case with a brass carrying hook situated at its top. The case is secured by a lock which is still functional and the key is kept with the accessories.

  German Cuff-Type Microscope

  The cuff-style compound microscope stands on a large oak base with a drawer. The brass microscope is connected to the base by 4 splayed short legs, one of which is connected to the sub-stage plano-concave mirror set in a gimbal. The instrument has a rectangular pillar which is connected to the screw adjustment controlled by the thumbscrew at the top of the pillar. The decorative sculptural triform stage has a circular cut out and attachment which is spring loaded to hold the slides. The instrument comes with a small bulls-eye condenser and specimen holder which connect to the stage via a pin. The body-tube is held by the arm which allows the body-tube to be adjusted by sliding it closer or further from the stage. The instrument can also be used as a simple microscope by detaching the nosepiece attachment and using it to examine specimens. An addition to the nosepiece of the body-tube allows the instrument to be used as a compound or simple microscope by removing the attachment or sliding the slide above the objective lens. The addition is spring-loaded which secures the slide in place. The eye piece has a protective cover which slides out of place. The base has one draw which holds the microscopes accessories and slides.

  Andrew Ross Microscope

  The brass microscope stands on a splayed Y-shape base and engraved with "Andw. Ross, London, No.190." This instrument represents the classic design created by Ross - the bar-limb and splayed Y-shape base - which was copied by many other manufacturers. The monocular instrument's limb is triangular in the cross section. The dual side pillars end in trunnion joints that allow for inclination. The square mechanical stage has an uppermost section which rotates clockwise and counter-clockwise. The stage can be adjusted along the X and Y axis with a rack and pinion mechanism. The stage also has a bullseye condenser and stage forceps attachments which are attached by a pin. The stage has a substage iris diaphragm which can be rotated. The receiver for the threaded objective is spring loaded, which in effect acts as a "safety-stage." Coarse focusing is achieved by a rack and pinion mechanism which is controlled by thumbscrew located at the side of the stage. Fine focusing works by a lever mechanism mounted within the bar proper and adjusted by a knurled thumbscrew mounted on the bar. The instrument has a substage plano-concave substage which is mounted in a gimbal. The microscope also comes with a stand-alone bullseye condenser with a circular stand. The mahogany glass-fronted case contains three internal accessory drawers.

  Smith & Beck "Milk Box" Educational Microscope

  This microscope is a rare example as it has a cast iron base which appears to have been purpose-built rather than retrofitted. The actual instrument has been stripped of its gunmetal and black lacquers. The microscope is signed with a stamped with "Smith & Beck, London" on the side pillar. The cast iron base is attached to the dual side pillars which end in trunnions that allow for inclination. The square stage has a substage iris diaphragm which can be removed and a substage plano-concave mirror set in a gimbal. Coarse focusing is achieved by sliding the body-tube through the cylinder attachment connected to the main pillar. The fine focusing is controlled by knurled knob at the base of the pillar and the cast iron base is attached to a mahogany accessories tray that holds the objective and objective lens. The mahogany case is secured by a lock and key, which is broken. The base slides into the case horizontally. The microscope design was low end and became eclipsed by the binocular version —  "Popular Microscope" —  by 1865. The instrument was described by Richard Beck in his book, A Treatise, in 1865 and reviewed by Gerald Turner in his book, The Great Age of the Microscope (1989).

  Watson & Son "Fram" Microscope

  The compound microscope stands on a tripod base, which is similar to the design used in W. Watson's more expensive instruments. The tripod ends in two uprights connected to the trunnion joint with adjustments that were similar to many other Watson models such as the Edinburgh and Royal. The double-sided substage mirror is housed in lacquered brass casing and set in a gimbal. The substage mirror is a screw focusing substage condenser which is similar to the American and German models. The mechanical square stage has two stage clips, one of which is spring loaded. The stage is designed along the Nelson form with U-shape cut out. This form of stage was used on this design from 1898 through 1913. The stage attachment can be moved vertically and horizontally by the two thumbscrews on the side in order to adjust the specimen for observation. "W. Watson & Sons Ltd. London" is etched into the stage. On the base, "W. Watson & Son Ltd. 15036", "FRAM" and "313 High Holborn London." are etched into the surface. Coarse focus functions by diagonal rack and spiral pinion which is controlled by the thumbscrews on either side of the body-tube whilst the fine focus is via a long lever controlled from the thumbscrew located at the top edge of the rear part of the arm. The Fram was an attempt at a slightly smaller and less expensive option than the earlier Edinburgh stand. The wooden case is original to the microscope and has a compartment to hold the lenses which can slide out.
