TitlePaper, 'Some observations on the amount of luminous and non-luminous radiation emitted by a gas flame' by John Conroy
Date1889
DescriptionConroy writes: 'In 1863 Julius Thomsen communicated to the “Naturforscherversammlung” at Stockholm an account of some determinations he had made of “The Mechanical Equivalent of Light,” and an abstract of this paper appeared in "Poggendorff's Annalen" (vol. 125, 1865, p. 348). He allowed the radiation from a sperm candle, a moderator lamp, and a gas flame, to fall on the face of a thermopile, and noted the deflection of the needle of a galvanometer in the thermoelectric circuit, when the radiation fell directly on the pile, and when it did so after passing through 20 cm. of water contained in a glass cell.'
