when we first began to see the eclipse through the clouds, I was 

 under the impression that the eclipse, instead of being total, was 

 only annular, so bright was the corona near the moon's limb. I 

 could not detect any UTegularities in the structure of the corona, 

 but the light appeared to be gradually shaded off all round." 



Dr. Janssen, who was at Guntoor, was principally occupied with 

 spectrum observations, but he gives a very graphic account of the 

 appearance of the long horn, which he says was more than three 

 minutes high, and shone with a splendour difficult to imagine. It 

 recalled the flame of a forge issuing with violence from openings in 

 the fuel, and driven by the force of the blast. The protuberance on 

 the right (the eastern edge) presented the appearance of a collection 

 of snowy mountains, whose base rested on the limb of the moon, 

 and which were illuminated by a setting sun. 



The ordinary observations at Wah-Tonne on the protuberances 

 were made by M. Stephan. He examined the phenomena of totality 

 in a large telescope, and describes the protuberances as appearing 

 with niarvellous sharpness: they were in four groups, arranged as 

 shown in Fig. 4 ; their 

 colour was described as 

 rose coral, slightly tinged 

 with violet; they all 

 seemed attached by a 

 perfectly distinct base, 

 and not to float at a cer- 

 tain distance above the 

 sun, as drawn by some ob- 

 servers in recent eclipses. 

 The longest protuberance 

 had a length which was 

 not less than the tenth 

 part of the lunar dia- 

 meter. 



During this eclipse it 

 was noticed by more than 

 one observer that the red 

 flames were not extinguished immediately after the totality had 

 passed over. Thus Dr. Weiss, at Aden, said that the large 

 horn remained visible for a minute after the sun had reappeared, 

 being only then lost in the clouds; and Dr. Oppolzer, who was 

 also at Aden, says that this same protuberance could be dis- 

 tinguished for thirty-seven seconds after the last moment of 

 totality. At Beejapoor, Mv. Kero Laxuman describes the great 

 protuberance as like a red flaming torch, streaked by several 

 dark red lines. He says it was visible " for about two minutes 

 after the end of totahty, and had there been no clouds I think it
