On the distribution of frequency (variation and correlation) of the barometric height at diverse stations

Although this paper contains the results of a very large amount of arithmetical work, which has been in progress during the last two or three years, it is not intended in the first place as a contribution to the meteorology of the British Isles It is especially intended as anillustration of method . The authors believe that hitherto no exact theory of variation or of correlation has been applied to meteorological observations, and they have endeavoured to indicate that fruitful results may be obtained from such a theory applied to one branch at least of meteorology, namely, barometric frequency.
