Comments on WL's observation of the seventh satellite of Saturn as noted in WL's 1846-8-26.
Received WS's note about G. B. Airy's action regarding new warrant for Board of Visitors. Feels that Airy's cooperation is necessary in light of anomalous position of one board member. Recommends referring matter to Admiralty.
The chemist C. F. Schönbein has invented a form of 'explosive cotton' and is looking for an opportunity to demonstrate it. JH is asking CP to help arrange matters.
Thanks [?] for the honor of having her book on astronomy dedicated to JH.
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.
Discusses JT's method for Great Circle sailing.
Not surprised that scientific journals decline simple mechanical explanation of heat based on principle of conservation of vis viva. Admits that it has advocates, but JH has no time to devote to it. [JH's annotation: Not sent. Waterston gave no address but 'London'.]
Thanks JC for the writing material [?] JC sent. Pleased at the prospect of JH's eldest son [William] serving in the East India Company. Discusses developments in India and some chemical processes.
