Table VI. exhibits the average value of an easterly compared with that of a 
westerly disturbed observation in the several months, found by dividing the aggre- 
gate easterly or westerly amount of disturbance by the corresponding number of 
occurrences.

It appears from this table that an easterly disturbance is very generally less in 
amount than a westerly disturbance. At bt. Helena there is but one month in the 
year in which the westerly disturbance falls below the easterly, and but three at the
