Relative Humidity. — The hygrometer at our disposal for 

 the measurement of the relative humidity of the air was very 

 imperfect, and its findings are uncertain as to their value. 

 Its readings, however, corrected by later comparison of 

 our hygrometer with another reliable instrument, furnish 

 the following conclusions, which can be regarded as having 

 only a relative value : The maximum humidity was 100, 

 the minimum 27.5, the mean 82. July was most moist, 

 with a mean of 93. August was dryest, with 76. September 

 had a humidity of about 80. Of our 245 observations, only 

 2,7 were as low as 65, and of these only eight were as low as 

 50, and only two 40 or under; 162 were 80 or more ; 127 were 

 90 or more. 



Pressure. — The barometric pressure ranged from 29.28 

 to 30.75, with a mean of 29.82. Wakeham, in 1897, between 

 June 27 and October 9, experienced a range from 29.31 

 to 30.37, with a mean of 29.82. On only three occasions up 

 to September 22 did the barometer rise above 30.20, one of 

 these occasions covering three days. From September 22 

 on, it was above 30.20 almost constantly, dropping below it
