[D8822ABA], Letter from Piromis H Bell to Thomas Alva Edison, August 2nd, 1888

Editor's Notes

"Having great confidence in your valuable opinion on practical scientific subjects, I would very greatly appreciate your volunteer opinon as to the value of a machine I have thought of, as perhaps available in metoeorology, to wit: ### The recording of the revolutions of a Crooke's Radiometer by an electrical recorder, the selective motion, or number of revolutions to indicate the comparative sunshininess or cloudiness of the days. ### It does not seem to be entirely [unclear] whether Crooks' raidioneter is entirely affected by heat or by light, or how much by either. ### If you could find liecnese to write me I would feel exceedingly obliged." Yours most obediently, Piromis H. Bell [Marginalia: "It has been definitely settled by conclusive experiments that the radiometer is [unclear] by heat. E" "They have a 1st class Thorshine Recorder recently brat. Out in London but I have not seen it. E." "Ans Aug 21/88"]
