Seven Spectra taken at intervals of two minutes during the course of a “blow.” In the first or slag period, the lines of manganese are alone visible. In the second, the lines and some bands of manganese and the yellow line of sodium are visible. After the second period, the change in the spectra, caused by rise of temperature is readily seen, the lines of iron and the bands of manganese become more numerous.

Spectra however differ not only with the metal blown in different works, but even with the same metal during different blows, according to the composition in the first case, and to the temperature in the second. But besides these variations there are certain broad facts which call for explanation. First, what is the nature of the flame? p 740

Having then proved that bright light had so strong an effect on woods and certain other bodies, the next step was to ascertain which waves were the most active in producing this effect. With this object stripes of different coloured glasses were laid on sections of different woods and then exposed to sunlight… Fig. 38 shows the action of a blue and a green glass and no glass on the wood… Many different woods were tried, but the effects produced in all cases were of precisely the same character. p 288

…revealed by the presence of small black points here and there towards which fine discharge lines proceed, and from which the discharge passed to the wire below. The form of these lines seems to have been somewhat affected by electro-magnetic induction from the discharge wire across the upper film. The fogging effect on a film from which electricity passes to a conductor, is much less than that caused by a like discharge of electicity against the film. p 14

I cherish a tender affinity with many of my „unknown“ followers. Even though we have never exchanged a word. (99,99 % - actually incredible after this long time) Even though I do not follow most of the followers because I am still, after a few years, not habituated to this chaos on my daily dashboard. But anyway, I often follow, accidentally, unpredictably these arising hearts. And I’m marveled about this incredible wonderful diversity, openness. And I thank you for all the daily hearts, and the links that create a network whose deeper meaning is still hidden for me. Except, perhaps, that since I develop this tender feeling for the connection with the unknown.
* Ich hege eine zärtliche Verbundenheit mit vielen meiner „unbekannten“ Follower. Durch die lange Zeit. Durch die regelmäßige Wiederkehr. Auch wenn wir nie ein Wort gewechselt haben. (99,99 % - eigentlich unfassbar - aber wunderbar, dass man so nah sein kann, ohne zu sprechen.) Auch wenn ich vielleicht nicht so vielen folge, da ich mich trotz der vielen Jahre Tumblr immer noch nicht an das Chaos des Dashboards gewöhnen kann. Aber trotzdem folge ich lustvoll und zufällig gerne den auftauchenden Liebhabern direkt auf Ihre Blogs zurück. Und staune über diese unfassbare Vielfalt. Und ich danke für all die täglichen Herzen, und die Verknüpfungen, die ein Netz kreieren, dessen tieferer Sinn mir immer noch verborgen ist. Außer vielleicht, dass ich seitdem dieses zärtliche Gefühl für eine Verbundenheit mit dem Unbekannten spüre.
