announced the approach of the moon. The eclipse had 

 begun. Rapidly advancing, the moon seemed to hold the 

 sun with iron grasp and to consume its light, the weaker

 scarcely perceptible till the sun was half hidden, from 

 that time grew rapidly more apparent. Darkness seemed

 restful night but by a cheerless gloom. A sense of awe 

 filled the soul. Men, with countenances changed to an

 wrought. The sun regained its power, the stronger vic- 

 torious over the weaker. Nature once more assumed her 

 wonted aspect. The eclipse was over. 



[The remainder of the lecture was illustrated by a 

 series of lantern views projected upon the screen by Mr. 

 Leonard Waldo of Cambridge. First were given views 

 of the recent eclipse as it appeared to the naked eye and 

 as seen through telescopes by different observers.] 



It is singular that the corona should appear so differ- 

 ently to different observers, even if they are at the same 

 station and view'lt under similar conditions. But since 

 this is an evident fact, it is natural to suppose that a more 

 accurate representation of the corona may be obtained by 

 photography. But there are several difficulties to be
