March 5. Wind South. 6th, Wind West, then North. 9th, Wind South: All doughty Weather with small Frosts. To these Meteors I might add our Hurricanes, Storms of Thunder and Lightning, with Hail or Rain; but such as keep Journals of the Weather, and read the public News, are no Strangers to these: I shall only add, that our Northern Lights have been much seldomer, and fainter, both in Appearance and Motion, than formerly; and whether they will dwindle away and vanish wholly for some Years, or whether they have had their former periodic Returns, is not certain: Nor is it less dubious, whether they affect our Weather, Seasons, and Animal Bodies, or not. Were it not too tedious, I might here subjoin a List of all the Chasms or Burnings in the Heavens, recorded in our Annals. XV. Mercurius a Venere sublatus Maii 17. 1737.
