DIRECTION AND 



The Observation of Direction and Force of Wind is made always on the roof of the Observatory. The 

 Scale used for pressure (0 to 12) lias been found by comparison with a Eobinson anemometer, mounted 

 18 feet above the roof, to have the following approximate values in miles per hour; the velocities corresponding 

 to force 9 and upwards are interpolated.
