Tyndall, John (1864). "On luminous [i.e., visible] and obscure [i.e., infrared] radiation". Philosophical Magazine. 4th series. 28: 329–341.; see p. 333.
In his physics textbook of 1875, Adolph Wüllner quoted Tyndall's results and then added estimates of the temperature that corresponded to the platinum filament's color:
Wüllner,Adolph(1875). Lehrbuch der Experimentalphysik [Textbook of experimental physics] (in German). vol. 3. Leipzig, Germany: B.G. Teubner. p. 215.
From (Wüllner, 1875), p. 215: "Wie aus gleich zu besprechenden Versuchen von Draper hervorgeht, … also fast um das 12fache zu." (As follows from the experiments of Draper, which will be discussed shortly, a temperature of about 525°[C] corresponds to the weak red glow; a [temperature] of about 1200°[C], to the full white glow. Thus, while the temperature climbed only somewhat more than double, the intensity of the radiation increased from 10.4 to 122 ; thus, almost 12-fold.)
