The Fraunhofer lines are also given according toAngstrom and Yogel, and the iron spectrum of the arc and sparkaccording to Angstrom and Thalen. The observations during theeclipse were made 7 minutes, 3 minutes, and 2 minutes before 1882.] On the Recent and Coming Total Solar Eclipses, 297 totality as tlie air was gradually darkened, by which darkeningsuccessive veils, as it were, were lifted so that the more delicatephenomena could be successively seen. Fig. 16. We begin with one short and brilliant line constantly seenin prominences, never seen in spots. ISText, another line appears, alsoshort and brilliant, constantly seen in prominences, and now, for thefirst time, a longer and thinner line appears, occasionally noted aswidened in spots, while last of all we get very long, very delicaterelatively, two lines constantly seen widened in spots, and anotherline not seen in the spark and never yet recorded as widened in thespots. 17. The procession from the hot to the colder is apparent, and thesimplicity of the spectrnm as opposed to the Fraunhofer spectrumeven yet, is eloquent of the gradual approximation which would bestill possible if the darkness could be greater and our attack morecomplete. 18. It will be noted over what an excessively small range theobservations extend. We want similar observations over a widerrange during future eclipses, and to do this work properly manyobserver
