Ananito. — The hourly values of Barometric Pressure are taken from 

 Met. and Phy. Observations on the East Coast of British 

 America, 1883. 



Cordoba. — The hourly values of Barometric Pressure for the year 

 are taken from Davis, Clitnate of the Argentine Republic, p. 51, 

 1902. The June and December values are from the Challejiger 

 Report. 



Great St. Bernard, Klagenfurt, Valentia. — The hourly values 

 of barometric pressure are taken from the Challenger Report. 



Agustia. — The hourly values of Barometric Pressure in Table i 

 are taken from the Indian Met. Memoirs, X., Part 2. They 

 are really for 30 minutes past the hour to which they stand 

 opposite. Thus 24.067 is the pressure at 1.30 a.m., 24.057 is 

 the pressure at 2.30 a.m., etc. 



Trevandrum. — The harmonic constants of Barometric Pressure for 

 this place are taken from Eliot, Indian Met. Memoirs, X., Part 

 I. The harmonic constants of Temperature Variability are 

 computed from the hourly values of temperature given in the 

 same Part. 



In Table 3 all the harmonic constants have been computed by 

 me, with the exception of those of Barometric Pressure for Ananito, 

 Calcutta, and Trevandrum, and those of Vapour Tension for 

 Cordoba. My Lisbon result agrees (after changing some signs and 

 putting inches for mm.) with those given in Annces do Obs. do 

 Infante D. Luiz, 1888. The time is counted from local midnight in 

 each case.
