Diagram of an electrical experiment on the strength of a derived current, proposed by Thomas Edison.
Figure 1 from the manuscript version of the paper ‘On a peculiar behaviour of glow-lamps when raised to high incandescence’, by William Henry Preece, Proceedings of the Royal Society, v.38 (1884), pp.219-230.
The accompanying text commences: ‘During my recent visit to America (October 1884), Mr. Edison showed me a very striking experiment with glow-lamps the principle of which he had not threshed out, although he had attempted to apply it practically to the regulation of the current flowing in Electric light circuits’.
Inscribed in pencil above: ‘Fig. 1’ and in ink below: ‘Preece (50) 1885’.
Sir William Henry Preece (1834-1913) British electrical engineer and inventor was elected a Fellow of the Royal Society in 1881.
