Friday 25 August 1665
Up betimes to the office, and there, as well as all the afternoon, saving a little dinner time, all alone till late at night writing letters and doing business, that I may get beforehand with my business again, which hath run behind a great while, and then home to supper and to bed. This day I am told that Dr. Burnett, my physician, is this morning dead of the plague; which is strange, his man dying so long ago, and his house this month open again. Now himself dead. Poor unfortunate man!
