Description

Image of a flea being projected by ‘Palmer’s improved portable oxy-hydrogen apparatus and microscope with prepared objects, complete.’ The equipment is mounted on a wheeled trolley in front of a screen, gas being piped from storage bellows to the projector for illumination of the microscope slides. What appears to be a safety water pump is also shown, with a pointing stick. The complete apparatus sold for £35.

Figure 274 (p.61) from Palmer’s new catalogue, with three hundred engravings... (London 1840).

The accompanying text states that: “E.Palmer begs to submit the following splendid Apparatus to the attention of Lecturers, Schoolmasters, and Scientific Gentlemen...To the scientific Lecturer it is an Apparatus of great value, as it enables him to exhibit to an audience many very interesting and beautiful phenomena connected with the various Sciences...All danger being obviated by the Gases being kept in separate vessels...”

Edward Palmer (active 1830s-1840s) of 103 Newgate Street, London, was a chemical and philosophical instrument maker who was an early provider of photographic (‘photogenic’) paper and associated chemicals, based upon the work of William Henry Fox Talbot FRS (1800-1877).
