The results for Greenwich were derived from the " Greenwich 

 Magnetic and Meteorological Observations." The instruments em- 

 ployed were Whewell's and Robinson's anemometers, the indications 

 of the former having been reduced to those of the latter in the 

 "Greenwich Observations for 1862. Introduction, p. 52." The re- 

 sults for Oxford were derived from the "Radcliffe Observations," and 

 the instrument employed was Robinson's anemometer. The results 

 for Liverpool were derived from the " Report of the British Associa- 

 tion for the Advancement of Science for 1855," and the "Radclifte 

 Observations for 1857." The observations were made with Osier's 

 anemometer. The results for Kew were derived from the " Radclifte 

 Observations for 1857." The results for Plymouth were derived 

 from the " Quarterly Journal of Meteorological and Physical Science 

 for 1842-3." The instrument emjiloyed was Whewell's anemometer. 

 The results for Brussels were derived from Osier's anemometer, and 

 are taken from the " Annales Meteorologiques de I'Observatoire royale 

 de Bruxelles." The numbei's denote pressure in kilogrammes, which 

 have been reduced to pounds per square foot, and hence has been 

 deduced the velocity in miles per hour in accordance with the Tables 

 of the British Board of Trade (see Loomis' Meteorology, page 277). 

 The results for Madrid were obtained from a Robinson's anemometer 

 made by Casella, and are taken from the " Observaciones Meteorolog- 

 icas Efectuadas en el Real Observatorio de Madrid." The results are 

 given in kilometers, and have been reduced to miles per houi\ The 

 results for Mitlhausen were deriA-ed from a Valz anemometer, :uid 

 were taken from " Schmid's Meteorologie," p. 501. The results are
