which these representations of the eclipse bore comparison with each 

 other elicited an exclamation of surprise from Dr. Kielhorn. The 

 comparison shewed as follows : — 



Protuberance a was shewn by the Professor straighter and not so 

 pointed as by me. The streaks composing its body, the angle at 

 which it met the moon's limb, and its height and position correspond- 

 ed very well. The position, structure, and height of the double 

 spot b, the same in both sketches. 



The spot marked by the Professor at c v was noted by me at c r 

 I am inclined to give way to the position he has assigned to this pro- 

 minence, as I believe that in my hurry I may have marked it in an 

 inverted position with regard to the double spot b ; it may be re- 

 marked that we have both placed it at the same distance from b. 



Captain Haig after just glancing at the sun through his telescope, 

 and satisfying himself as to the existence of red flames, proceeded at 

 once to examine them, and the corona with his spectroscope. The 

 latter though most markedly visible to the naked eye gave but a 

 faint continuous spectrum, whereas the red flames although totally 

 invisible to unaided sight, shone out brilliantly and conspicuously 

 across the dark disc of the moon. 



Captain Haig's report to Colonel Walker fully describes his observa- 

 tions, which he hopes will corroborate those of other observers who 

 have been furnished with complete apparatus for analyzing the con- 

 stitution of the corona and red flames. 



Kern Luximun and I are almost unfortunate in being perhaps the 

 first observers to notice the streaky lined structure of the red pro- 

 tuberances. 



I would therefore offer the following suggestions as to the probable 

 or perhaps possible reason for our having noticed them. 



When the sun is ordinarily observed on a bright warm day, the 

 tremulous motion of the atmosphere so interferes with magnified views 

 of sun-spots, that the minute markings of their structure are almost 

 if not quite lost and obliterated. Now we observed through a single 

 gap in the clouds. The earth and atmosphere had not been warmed 

 at all by the sun's rays that morning, and we therefore saw the sun 

 through a perfectly steady and homogeneous atmosphere, undisturbed 

 and unbroken by heated tremulous vapour ; the streaks and lines com- 

 posing the red protuberances were therefore seen by us distinct from
