A N A L Y S I S OF THE 



The minimum amount of disturbances in the eleven year circle, therefore, occurred 

 in the beginning of 1844. 



The minimum of the eleven year period is equally well marked in the disturb- 

 ances increasing and in those decreasing the inclination. The sum of the positive 

 values (1603/5) is to the sum of the negative values (822/1) as 1.95 to 1. At 

 Toronto, between 1844 and 1848, this ratio was 5.6 to 1 ; the ratio, however, 

 increased from 2.7 to 8.5 to 1 during this time. 



In Tables V and VI, which exhibit the diurnal inequality of the disturbances, 

 the whole series between February, 1841, and June, 1845, is employed. The sums, 

 numbers, and ratios given do not in strictness apply to the even hours, but to an 

 epoch 20 minutes later.
