Up, and to the Office, where all the morning. At noon home to dinner, and Captain Deane with us; and very good discourse, and particularly about my getting a book for him to draw up his whole theory of shipping, which, at my desire, he hath gone far in, and hath shewn me what he hath done therein, to admiration. I did give him a Parallelogram, which he is mightily taken with; and so after dinner to the Office, where all the afternoon till night late, and then home. Vexed at my wife’s not being come home, she being gone again abroad with M. Batelier, and come not home till ten at night, which vexed me, so that I to bed, and lay in pain awake till past one, and then to sleep.
