Report of Captain Campbell, Assistant Surveyor General, Baramahl 

 Survey, to the Secretary to Government, General Department. 

 I have the honour to report to you, that the Barometers in the 

 office of the Salem and Baramahl Survey, at present in quarters at 

 this station, have marked the progress of the hurricane which ap- 

 pears to have visited Coringa on the 16th November, The Barome- 

 ters are two, on the Syphon plan, and have been filled wet. By 

 continued comparison it has been found that the greatest difference 

 between the two is about .04 of an inch, and the least .02 inch, 

 which difference appears to be less than the error between Mr. James 

 Prinsep's standard Barometers. The instruments may therefore be 

 relied on. From the observations, it appears, that the Barometer 

 commenced falling here on the 6th November, and continued to do 

 so regularly till the greatest depression was attained on the 20th, at 

 4 p.m. of the afternoon observation, and at 10 a.m. of the 21st No- 

 vember of the morning observation ; from that time, it regularly rose 

 until the 26th November, when it indicated the same pressure as 



on the 6th. The greatest difference between the pressure on the
