Direction of the Wind, New Haven, Conn. 



expressed in Paris feet per second, which have been reduced to miles 

 per hour. Tlie i-esults for Madras, India, were derived from Osier's 

 anemometer, and were taken from the " Madi'as Meteorological 

 Observations." The pressures expressed in pounds per square foot 

 have been reduced to velocities in miles per hour by Loomis' Table. 

 The results for the Cape of Good Hope were derived from Osier's 

 anemometer, and were taken from the first number of the " Meteoro- 

 logical Papers of the Board of Trade, London, 1857." The results 

 are given in pounds pressure per square foot, and have been reduced 

 to velocities in miles per hour. The Philadelphia observations were 

 made with Osier's anemometer, and are taken from the " Magnetic 

 and Meteorological Observations at Girard College." The results, 

 which are given in pounds per square foot, have been reduced to 

 velocities in miles per hour. The results for Wallingford, Conn., 

 were derived from Osier's anemometer, and are given in ounces of 

 pressure on a surface of 100 square inches, which have been reduced 

 to velocities in miles per hour. The observations for New York City 

 wei'c made with Robinson's anemometer, and ave taken from the 

 " Thirteenth Annual Report of the Board of Commissioners of the 

 Central Park." The observations at Toronto, Canada, were made 

 with Robinson's anemometer, and are derived from the " Abstracts of 

 Meteorolosfical Observations made at Toronto from 1854 to 1859." 



Table VIII.- 



Mean Monthly and Annual Velocities of the Wind, 

 in miles per hour. 



Table VIII contains a summary of the mean monthly and annual 

 velocities in miles per hour for each of the preceding stations. The 

 stations are arranged in the order of the mean velocity of the wind. 

 New Haven shows a less velocity than any other of the stations, 

 excei)t Cairo in Egypt. The observations for Cairo emljrace only 

 four months of the year 1865, and are derived from the "Appendix 

 to the Edinburgh Astronomical Observations, Vol. XIII."
