Up, and to the office, where all the morning very busy, and at noon took Mr. Hater home with me to dinner, and instantly back again to write what letters I had to write, that I might go abroad with my wife, who was not well, only to jumble her, and so to the Duke of York’s playhouse; but there Betterton not being yet well, we would not stay, though since I hear that Smith do act his part in “The Villaine,” which was then acted, as well or better than he, which I do not believe; but to Charing Cross, there to see Polichinelli. But, it being begun, we in to see a Frenchman, at the house, where my wife’s father last lodged, one Monsieur Prin, play on the trump-marine, which he do beyond belief; and, the truth is, it do so far outdo a trumpet as nothing more, and he do play anything very true, and it is most admirable and at first was a mystery to me that I should hear a whole concert of chords together at the end of a pause, but he showed me that it was only when the last notes were 5ths or 3rds, one to another, and then their sounds like an Echo did last so as they seemed to sound all together. The instrument is open at the end, I discovered; but he would not let me look into it, but I was mightily pleased with it, and he did take great pains to shew me all he could do on it, which was very much, and would make an excellent concert, two or three of them, better than trumpets can ever do, because of their want of compass. Here we also saw again the two fat children come out of Ireland, and a brother and sister of theirs now come, which are of little ordinary growth, like other people. But, Lord! how strange it is to observe the difference between the same children, come out of the same little woman’s belly! Thence to Mile-End Greene, and there drank, and so home bringing home night with us, and so to the office a little, and then to bed.
