Somewhat hazy. | From this time the barometer rose till the 20th, when, at 8¼ M. it was up at 30,44, the sky covered, wind N 2. Then it fell till the 23d at 6½ E, when it was so low as 28,87; which was lower than it had been since the 6th of February last. The afternoon of the 22d, and night following, when we had another shock, it was calm, and rained 1,205 inches. This leads me to observe, that though the _serenity_, as well as _calmness_, of the air, is a circumstance taken notice of in many earthquakes, both in this and in other parts of the world; yet it does not always obtain, at least in the smaller shocks, and, so far as I have had opportunity to observe, the _calmness_ of the air has more constantly attended upon earthquakes, than its _clearness_. The white frost on the morning of the earthquake, which, when melted, I found to be of the depth of 17/1000 of an inch, was almost double of any white frost we have had for seven years past, and about five or six times as great as we commonly have. The barometer and thermometer underwent no alteration at the time of the earthquake: only, my barometer, which has an open cistern of quicksilver, and stood in a chamber, was so agitated, that part of the quicksilver was dashed over the sides of the cistern, and scattered upon the floor. This cistern was a cylindric cup, whose sides were an inch higher than the surface of the quicksilver.
