The balls diverge five- eighths of an inch, full. Prefently, after I had fixed my rod, there fell fome fmall drops of rain. Upon the moment of its fallings the balls increafed their divergence near, or quite, a quarter of an inch. I never faw a fog more ftrongly electrified when the weather was fo warm, the mercury in my thermometer, in the open air, being feven and an half degrees above the freezing point. I fup- pofe higher in the atmofphere it is now uncom¬ monly cold. Fifty minutes paft two, P. M. It fnows very faft. The air is now ftrongly eleftrified poftively. The balls feparate full three quarters of an inch. Wind S. W. From the fmall number of experiments I have been able to make, on the electricity of the atmo¬ fphere, I cannot help being of opinion, that fogs are much more ftrongly electrified m9 or immedi¬ ately after, a frof, than at other times; and that the eiedricity in the fogs is often the ftrongeft, F foon](https://iiif.wellcomecollection.org/image/b30791005_0059.jp2/full/800%2C/0/default.jpg)
