The instruments used in the foregoing observations arc placed upon a 

 table 3 feet high in the western verandah of the Honourable Company'* 

 Observatary ; from the Mean of five Barometrical measures lately made 

 the floor of the verandah appears to be about 26 feet above the level of the 

 sea (not 45 as was before erroneously supposed.) The barometrical indica- 

 tion are those read off from the instrument, without any reduction for cappil- 

 iary action or temperature ; for the former, the correction answering to 0,20 

 inches diameter or -|-, 059 inches should be employed— The Madras Ob- 

 servatory is situated at about two miles from the sea in longitude 6 hours 

 21 minutes 9 seconds east of Greenwich and IS degrees 4 minutes 9 se- 

 conds north latitude.
