Total Eclipse of August 7, 1869. 205 



While sweeping the disk in search of the red protube- 

 rances if any should appear before totality, I missed the 

 contact with the large eastern spot, but noticed soon after 

 the formation of Bailey's beads, and as I heard the signal 

 key record the time, I did not note it by the watch. 

 The beads appeared to me to cover about 60 degrees of arc, 

 and their duration to be from 5 to 8 seconds. They were 

 somewhat irregular in their formation and of different 

 lengths, but presenting a very beautiful appearance. Ap- 

 pearing as they did at a point coincident with the mount- 

 ainous or rough edge of the moon, observed at first contact, 

 it seems to me not difficult to account for their formation. 



My observations of the total phase was also coincident 

 with the record of your signal key, and as soon as noted, I 

 commenced sweeping the disk for the red protuberances. 

 I was first struck with the size and appearance of the one 

 on the lower quarter, then the double hooked one on the 

 western edge, and then the two upon the eastern side, as 

 marked in the accompanying diagram. The color was of 

 dark deep red, having a somewhat lighter shade near the 

 outer edge. 



I was also conscious for a few seconds of the appearance 

 of a continuous series of small ones or rather perhaps a 

 red line with an occasional break on the S. W. quarter. 



My observations of the corona were imperfect in conse- 

 quence of not taking it all in the field of my glass. It 

 showed white rays of varying lengths in different positions, 

 giving the appearance of fine points. With regard to its 

 general features, my impressions accord well with the dia- 

 gram prepared by Prof. Murray. I, however, received an 

 impression of its assuming a roseate tint near the end of 

 totality. I regret that I had not been more particular in 

 my observations, as the apparent change of tint does not 

 appear to have been noticed. Probably it was an effect 

 produced by the colored shade I had previously used.
