sufficient to be of service in practical meteorology. Still better results 

 could probably be obtained by making the prediction for one station 

 depend upon observations at two or more other stations, so situated as 

 to give suitable intervals for maximum correlation* ; and it may also 

 be desirable to take into account the height observed on the previous 

 day at the station for which the prediction is required, for the results 

 given in Table III show that in some cases, at any rate, there is a 



* It would be of little use to predict for intervals of only 5 or 6 hours ; at least 

 24 hours would be desirable, if this does not make it necessarv to take distances so 

 great as seriously to weaken the correlation.
