…About 2:30 we had a tempest of thunder and lightning, and a great deal of rain. The thunder had been heard all the morning from about 5:20. The storm here was not very severe, neither the thunder nor lightning so sharp as I have heard, but it was excessive dark, and I dare say was very severe both to the southwest and southeast of this place. But it passed over here pretty light. I do not remember ever to have seen the heavens in so seeming a tempestuous situation as they were today, the whole element seeming in a commotion. It did not last a great while here.
Sam Jenner drank some coffee with me, it being a wager I lost. At home all day and thank God very busy. In the evening wrote my London letters. Robert Hook a-gardening for me part of the day. In the afternoon Sam Jenner and I played a few games of cribbage.
