Wonders how [Christian?] Schönbein, who is in London, could best exhibit explosives. Hopes RM will attend upcoming meeting; [William] Stratford, who is ill, cannot. [Francis] Baily, [Thomas] Henderson, and [R.] Harris have died working on 'fatal' catalogue Stratford is doing.

Received JH's letter without the enclosure from C. P. Schönbein, but has now received a letter from Schönbein. Has advised him to come to the Southampton meeting. Has written his discourse and would welcome a paragraph from JH on physical science and on some of the foreigners expected at the meeting. What can he say about Carlo Matteucci? Had letter from William Whewell, who wishes to meet H. C. Oersted.

Thanks for his letter and C. F. Schönbein's. Will go on board the Excellent via rail to Gosport. Encloses what he has written on Michael Faraday for JH's amendments. Regarding the dinners at the meeting.
