Table IV gives the mean values of relative humidity and vapour 
pressure in millibars at Belvoir Castle for the 25 years 1896 to 1920, 
based on readings of dry and wet bulb thermometers at g h. and 21 h. 
The tabulations of hourly values of relative humidity at observatories 
show (a) that the average value of the relative humidity at g h. and 21 h. 
gives a close approximation to the mean for the day, and (b) that the
