5. Aurorce accompanied with Sound. 



1835. Nov. 18. Streamers accompanied with a crackling noise, 

 very distinctly audible. Most of the streamers on this 

 occasion were in the southern part of the sky. 



1839. Sept. 3. Sound of streamers like that produced by striking 

 the air sharply with a switch. This aurora was seen in 

 North America. 



1839. Sept. 4. Aurora more hazy than that of last night, and in 

 the form of sheets flashing wildly up to the coronal point, 

 accompanied with a " xvhiffling " sound. 

 N.B. Except in the above instances, I have never heard sounds 



given forth by the aurora ; in these cases the streamers probably 



descended lower than usual.
