CLIMATOLOGY. 



Ill 



the county boundary the quantity of rain which falls is no doubt 

 considerably higher than is represented by the highest figures 

 which we have given. The rain-clouds which gather round the 

 peaks frequently do not reach the dales and an excursionist 

 from the towns at the head of the western dales often gets 

 thoroughly wetted during a climb amongst the hills and on 

 returning to the starting point finds that little or no rain has 

 fallen there. 



The Mean Humidity of the Atmosphere. — By calling in the aid 

 of the wet and dry bulb thermometer we are enabled to obtain 

 a far more precise idea of the real humidity of the atmosphere 

 than we can get by considering the rainfall alone. The following 

 table gives, for four of the stations of which the rainfall has 

 been already stated, the average humidity of the atmosphere 

 month by month, taking saturation at loo, and in a fifth 

 column that of Greenwich is appended.
