can be applied by any one, and Avill conduce to consistency and 

 accuracy in the recording- of observations. 



The ^^^•iter had hoped to apply the proposed scheme in the following- 

 out of a series of daily observations, but many things interfered with 

 the carrying- out of this plan, and it was only possible to make oc- 

 casional observations as opportunity olfered, which might be used in 

 estimating the value of the scheme. On these occasions the following 

 data Avere carefully noted: the date; the character of the day, includ- 

 ing the state of the weather, the temperature, and the direction of the 

 wind; the character of the previous day's weather; the exact route 

 followed with the distance covered, as closely as it could be estimated; 

 a careful description of the territory covered; and the hours during 

 which the record was made. The following two reports will serve as
