Observations of Meteors, on the night between the \2th and \2>th 

 November 1841, 7nade at the Magnetic Observatory at Simla. 

 Communicated by Captain J. T. Boileau, Engineers, F, R. S. ^c. 

 ^c. Superintendent, 



The observed recurrence of numerous meteors on the same night, 

 during a series of years, having led to a belief in their periodicity ; it has 

 been become a special duty at all the fixed Magnetic Observatories 

 tp watch for their appearance, on the dates in question ; the nights of 

 the 10th August, and of the 12th November, have afforded the most 

 remarkable instances of their recurrence, both as regards their number, 

 and the regularity of the phoenomenon. Our labours here, on the 

 former night, were fruitless — not a single meteor having been visible ; 

 but the following account of those observed on the night between the 

 12th and 13th instant, confirms the fact, as regards the latter date. 

 It is to be hoped, should similar observations of these meteors have 

 been made in other parts of India, that an account of their appearance 

 may be forwarded for publication, in the Journal of the Asiatic Society, 

 without delay.
