Notes on Meteors. 



" 1845. August 10th. Watched for the ' meteoric shower ' of this 

 period ; but no meteors whatever were seen. The moon shone quite 

 brightly, while the sky was about half covered with cirro-stratus 

 cloud. 



^^ August llth. A brilliant meteor was seen from the Sears Tower, 

 in broad daylight, at 6*"- OS"*-. Altitude, 25° 30'. Azimuth south, 

 75° east. It described an arc of about seven degrees in one second 

 of time. The color was white, appearing to increase in brilliancy ; 

 the form irregular, the estimated diameter less than five minutes. The 

 sky was nearly clear in the direction where the meteor was seen, the 

 sun shining dimly at the time through cirrus cloud. The intensity of 

 the light of this meteor was such as to render it a more conspicuous 

 object than the moon at full would have been. The same meteor was 

 probably seen in Essex, Connecticut, and in the vicinity of Cincinnati, 

 Ohio ; but the accounts are not sufficiently precise to enable us to de- 

 termine its course and distance. 



" August 25th. A meteor was seen from the vicinity of the College 

 buildings, at about eight o'clock. It appeared of one half the diameter 

 of the moon. By a comparison of the different accounts, its altitude,
