The westerly disturbances therefore decidedly preponderate at both stations over 
the easterly in the aggregate of each year, both in frequency and amount. At 
Hobarton a similar preponderance of westerly over easterly was found in every year ; 
but at Toronto, on the contrary, the easterly disturbance exceeded the westerly m 
every year (though they were nearly equal in 1841 and 1847) ; yet on the average ot 
seven and a half years’ observation the easterly disturbances were in proportion to the 
westerly, as 1-17 to 1 in number, and as TIG to 1 in value. 
Dividing the disturbances into the several months of their occurrence, we have m 
Table! V. the ratios in each month of the number of disturbances, of their values, and 
of the average value of one disturbance to the mean monthly values.

From this table we find that January is the month ot greatest disturbance m 
frequency and value, and June of least disturbance, both at St. Helena and the Cape. 
On referring to the Hobarton observations, the very same months are found to be 
those of greatest and least disturbance respectively, but at Toronto loth January 
and June are months of minimum disturbance ; the maximum disturbances in the 
year occurring at Toronto in April and September. 
In comparing the observations at Toronto and Hobarton alone, it was found that
