- 'Sound and Radiant Heat', Popular Science Monthly vol. 20 (March 1882), summary of the 1881 Bakerian Lecture. [web] https://en.wikisource.org/wiki/Popular_Science_Monthly/Volume_20/March_1882/Sound_and_Radiant_Heat - "a recently published paper by Lecher and Pernter, who, while supporting the lecturer in the matter of gases, dissent from him in the matter of vapors ... especially emphatic in affirming the neutrality of aqueous vapor to radiant heat. Following Magnus, they refer Tyndall's results to vapor-hesion". - Rock-salt plates brought together and separated: sulphuric ether vapour, 1/20 inch gap gives 2 per cent, 2 inches gives 35 per cent; "Such experiments, recently verified, entirely dispose of the hypothesis that liquid films were the cause". (Tyndall's account; interested party.) - 29 Nov 1880 Graham Bell's photophone at the RI; Tyndall concluded the sounds came from intermittent absorption of radiant heat; Rontgen named "an independent and successful worker in this field". Meteorology: Magnus's "mist or haze" against Wells's observations; Wilson, Six, Leslie, Denham, Hooker, Livingstone, Mitchell, Strachey. Bearing: claim 2 (the vapour dispute was live in 1880-81 with Vienna experimenters dissenting); claim 5 (sounds from free molecules as evidence that absorption is molecular, not a film).
- 'On Radiation (Rede Lecture)', validated transcription. [web] https://en.wikisource.org/wiki/On_Radiation_(Rede_Lecture) - Gas table: air, O, N, H 1; carbonic oxide 750; carbonic acid 972; hydrochloric acid 1005; nitric oxide 1590; nitrous oxide 1860; sulphide of hydrogen 2100; ammonia 5460; olefiant gas 6030; sulphurous acid 6480. Perfumes: ... aniseed 372. This independently confirms the deep reader's page-image corrections (1590 not 1890, 6030 not 6080, 372 not 872). - Footnote on calorescence through coloured glasses: "in the case of certain specimens of blue glass, the platinum foil glowed with a pink or purplish light. The effect was not subjective". Same passage appears in Fragments of Science (Gutenberg and Commons copies, seen in Google results), so the pink glow was kept in later reprints; no report of a later check found yet.
