DISTURBANCES OF THE INCLINATION. 



exhibit the proportion of the amount of disturbances during any given sub-period 

 to the average amount of disturbances during the whole period. In the first and 

 three subsequent tables the values for the first five months of 1841 are omitted, as 

 there are no adequate means of extending the series beyond four full years. 



It would appear that during the colder season both sets of ratios present greater 

 values ; between September and February (inclusive) this ratio is, on the average, 

 1.16, and in the other months it is 0.84. Of the ratios decreasing the inclination 

 the September and November values are somewhat anomalous, the first too high, 

 the second too low. 



The following table gives the annual inequality of the disturbances, irrespective 

 of their sign. 



The ratio near the autumnal equinox is the greatest of all, that abdut the vernal 

 equinox is a little below the average value ; the least value occurs probably near 

 the summer solstice.
