The close apiiroximation of the mean of observations at 7, 2, and 9, 

 over the world, to the mean of twenty-four observations a day is striking 

 and gratifying. 



ANEMOMETER. 



The following is an account of the anemometer for registering the 

 direction and time of changes of the wind, in operation at the Smith- 

 sonian Institution : 



It consists principally of a light vertical shaft of wood, or iron gas 

 pipe, A B C, of about twenty feet long, passing through a round hole 

 in the roof of the high tower of the Smithsonian building, and con- 

 necting a horizontal vane at its upper end, and a recording pencil 

 moved by a clock at the lower end. This shaft is sustained above the 

 roof in an upright position against the pressure of the wind by a rec- 

 tangular brace d, firmly fastened at its lower extremity. The small 

 cylindrical hole in the roof through which the shaft passes has three 

 window sash rollers fastened into its circumference, to prevent friction
