A very fine day. Finding my business pretty nearly concluded for the time, I devoted the greater part of the morning to the examination and study of the English coinage, connected with the acquisitions I have made since my residence was made here. This is now easy through the purchase I made of Snelling’s work at the last sale. I now think of preparing a catalogue of this division of my collection, to fill up space hours of my time with. My first object is to methodize what I have so far as I can do it by the aid of the imperfect bits I brought with me in my general book. For a wonder I had no interruption after the morning when Mr Cyrus W Field came in to see me, just over in the Persia, about the Telegraph, which I fancy goes rather badly. Lonely walk. Dined by invitation with Mr and Mrs Romilly. The company consisted of Mr and Mrs Laugel, Mr and Mrs Mallet, Mr and Lady Georgiana Romilly, and Sir Henry Holland. It was rather pleasant than otherwise; but not so much so as the one last year, when Mrs Kemble Butler furnished so much amusement. Home by eleven.
