Abstract
APPEARANCES would indicate that we are now approaching the epoch of maximum, both as regards the disturbances of terrestrial magnetism and also as regards solar disturbances or sun spots; for these interesting phenomena are believed to march together. There is still a third phenomenon intimately connected with magnetic disturbances, and that is, the Aurora Borealis, a meteor which seems to sympathise with the terrestrial magnetic system to such an extent that when this is fluctuating and disturbed, displays of the Aurora are almost sure to follow.
