252 RESULTS OF THE METEOROLOGICAL OBSERVATIONS TAKEN DURING 



Westerly winds have a pressure aud temperature closely approximating to the 

 average, with a low humidity, cloud less than the average, and wind force also in close 

 agreement with the normal. 



Southerly winds have a high pressure and arc light in force, have a very low 

 temperature and humidity, and are accompanied by a relatively small amount of cloud. 



Easterly winds are strong, with a low barometric pressure, much cloud, and the 

 humidity in excess of the normal. 



With Calms pressure is high, but temperature, humidity, and cloud are all much 

 below the average. (See Plate I.)
