IN THE MEAN EFFECTS OF THE LARGER MAGNETIC DISTURBANCES. Ill 
II. Inequality or Variation in the numbers and values of the disturbed observa- 
tions in different months. 
The following' Tables X. and XI. show the ratios of the numbers and aggregate 
values of the disturbed observations at Toronto and Hobarton in different months to 
the mean monthly number and aggregate value taken as the respective units.

It is obvious, on the mere inspection of these Tables, that there is a systematic 
variation in the numbers and aggregate values of the disturbances in the different 
months ; and as at both stations the easterly and westerly ratios, separately con- 
sidered, differ little, in the characters which they assign to the variation, from the 
ratios of the two combined, we may fix our attention chiefly on the two final columns 
of each table. 
The most distinctly marked feature is that the disturbances are less frequent, and 
have a less aggregate value in November, December, January and February at Toronto,
