THE ACCESSORIES OF AN 1844 ORIGINAL FORM OF 'NEW MICROSCOPE' OF POWELL & LEALAND

MAKER: POWELL & LEALAND

MODEL: 'NEW MICROSCOPE'

ACCESSORIES:

This page illustrates another set of the original accessories supplied with the first version of the Powell and Lealand's 'New Microscope' of 1843. This example is from another private collection. Scroll down for an illustration below that is labeled with letters identifying the contents.

The accessories of an identical microscope, but made a year later, in 1844, from a private collection are pictured on this page. They include an understage simple wheel of apertures, a lensed understage condenser, a limb-mounting bullseye condenser, two live boxes, multiple objectives, multiple eyepieces, three darkwells, a stage forceps, a hand forceps, a substage polarizer, a Soemering-type camera lucida, lieberkuhns, a supplementary slide rest*, and an eyepiece analyzer. Some examples have a prism which attaches to the bottom of the condenser via a round clamp, to be used instead of a mirror. With this same example, and fitting separately into a drawer in the main case, are an eyepiece micrometer, a lever compressor, a large frog plate, and a larger top stage plate(left) designed to be used in place of the other top plate for larger slides and apparatus, like the frog plate. Unlike the main stage plate, this plate is not sprung as a safety stage and is therefore, although larger, it is at the same time, thinner.

*this attached under the fixed slide rest on the sprung stage plate and protrudes upward thus more firmly securing thicker accessories.
