Placed with its point downward, the cone indicates the approach of a storm from the south. A cylinder is the signal for a hurricane or a rotating...

That ring has a kind of rotary movement around the magnetized cylinder, sometimes in one direction and sometimes in another, according to the direction of the discharge, and the sense in which the magnetizing was done. Finally, some jets of light more brilliant than the rest seem to shoot forth...
