Up, and with Reeves walk as far as the Temple, doing some business in my way at my bookseller’s and elsewhere, and there parted, and I took coach, having first discoursed with Mr. Hooke a little, whom we met in the streete, about the nature of sounds, and he did make me understand the nature of musicall sounds made by strings, mighty prettily; and told me that having come to a certain number of vibrations proper to make any tone, he is able to tell how many strokes a fly makes with her wings (those flies that hum in their flying) by the note that it answers to in musique during their flying. That, I suppose, is a little too much refined; but his discourse in general of sound was mighty fine. There I left them, and myself by coach to St. James’s, where we attended with the rest of my fellows on the Duke, whom I found with two or three patches upon his nose and about his right eye, which come from his being struck with the bough of a tree the other day in his hunting; and it is a wonder it did not strike out his eye. After we had done our business with him, which is now but little, the want of money being such as leaves us little to do but to answer complaints of the want thereof, and nothing to offer to the Duke, the representing of our want of money being now become uselesse, I into the Park, and there I met with Mrs. Burroughs by appointment, and did agree (after discoursing of some business of her’s) for her to meet me at New Exchange, while I by coach to my Lord Treasurer’s, and then called at the New Exchange, and thence carried her by water to Parliament stayres, and I to the Exchequer about my Tangier quarter tallys, and that done I took coach and to the west door of the Abby, where she come to me, and I with her by coach to Lissen-greene where we were last, and staid an hour or two before dinner could be got for us, I in the meantime having much pleasure with her, but all honest. And by and by dinner come up, and then to my sport again, but still honest; and then took coach and up and down in the country toward Acton, and then toward Chelsy, and so to Westminster, and there set her down where I took her up, with mighty pleasure in her company, and so I by coach home, and thence to Bow, with all the haste I could, to my Lady Pooly’s, where my wife was with Mr. Batelier and his sisters, and there I found a noble supper, and every thing exceeding pleasant, and their mother, Mrs. Batelier, a fine woman, but mighty passionate upon sudden news brought her of the loss of a dog borrowed of the Duke of Albemarle’s son to line a bitch of hers that is very pretty, but the dog was by and by found, and so all well again, their company mighty innocent and pleasant, we having never been here before. About ten o’clock we rose from table, and sang a song, and so home in two coaches (Mr. Batelier and his sister Mary and my wife and I in one, and Mercer alone in the other); and after being examined at Allgate, whether we were husbands and wives, home, and being there come, and sent away Mr. Batelier and his sister, I find Reeves there, it being a mighty fine bright night, and so upon my leads, though very sleepy, till one in the morning, looking on the moon and Jupiter, with this twelve-foote glasse and another of six foote, that he hath brought with him to-night, and the sights mighty pleasant, and one of the glasses I will buy, it being very usefull. So to bed mighty sleepy, but with much pleasure. Reeves lying at my house again; and mighty proud I am (and ought to be thankfull to God Almighty) that I am able to have a spare bed for my friends.
