Note. — The Thermometer used has been checked 

 against a standard instrument; the necessary correction 

 is + 0-15°. 



The Araometer has been checked by titration, and 

 the following correction must be applied : — Correct in 

 the usual way for temperature (K in Knudsen's tables), 

 then add 0'20 to the corrected reading to get p 17 . 6 . 



For example, on August 7th, at noon, the corrected 

 temperature would be 1307 and the araometer reading 

 corrected for temperature becomes 2623 and, with the 

 final correction /o 17 . 5 = 26"43 and S = 34' 60 % . 

 The readings on the 8th when corrected give slightly 

 lower results, but that on the 12th at 1.30 p.m. gives 

 S = 34"61°/ O0 , and this is the highest of the series.
