Letter from Joshua Ramsey, on the cost of constructing furnaces for the use of the Optical Glass Committee "Of the active Committee of Michael Faraday, George Dollond and Herschel, Faraday was to analyse chemically the glass in use and to devise experimentally a better glass, Dollond was to act as a practical optician and Herschel was to test its optical properties".
