morning till about ten or eleven, when it 
arrives at its minimum; from tbat time it 
goes on increasing, till four in the after- 
noon, and, in the latter montlis, till six or 
seven in the evening. This force afterwards 
decreases anew during the night, and 
about three in the morning reaches its 
maximum; whenee it again returns, by 
little and little, to its minimum about ten 
or eleven in the morning, and so on con- 
tinually. 
Second ; that whenever the moon passes 
the equator the magnetic intensity is con- 
siderably weaker in the two or, three fol- 
lowing days. 
Third; that the magnetic intensity is 
still more reduced, during the appearance

of an aucora borealis, and is: so much the 
weaker as this meteor is extensive and 
powerful, The common intensity returns 
only by degrees, and twenty-four hours 
afterwards, 
Fourth; that the magnetic intensity ap- 
pears to have a very considerable annual 
variation, being stronger in the winter 
months than in the summer months. 
When the magnetic cylinder thakes’ 300 
oscillations’ in 813.6 seconds’ of time, I as- 
sume the corresponding intensity = 1°0000, 
and, as the intensities are in the inverse 
ratio of the squares of the time of the oscil- 
lations, we can always express, in these 
supposed parts, every intensity answering 
to the times of the oscillations. —
