Thanks JH for his recent writings on double stars, and comments on a number of observational issues related to the same topic.
Wants information for the journal. Apologizes for the delay in writing the letter.
Sends two articles for the R.A.S. Gained much pleasure from reading JH's Prelim. Discourse. If JH has written any other books for Lardner's Cabinet Cyclopaedia, he would be glad to receive copies. Work on Light has made great impression. Has Charles Babbage finished his Logs. yet? Cholera prevalent in Vienna.
Regarding JH's actinometers, intends to compare their results when in Switzerland and would be pleased if JH has any determinations on them. Outlines the plan of his experiments. Thinks JH should publish an account of them before JF publishes the results of his experiments. Met L. A. J. Quetelet in Brussels. Intends visiting the Pyrenees.
Has sent off his observations by the coach. Account of the Oxford meeting is in Tilloch's Magazine, now amalgamated with David Brewster's Edinburgh Journal. Will be able to include the new catalogue of stars in the forthcoming volume if JH desires it.
Thanks for his angry effusion. His non-reply to WF's paper proves that his theories must be correct.
Regrets a hasty opinion should have evoked so long a letter. Regarding the status of cholera. Would be grateful for a specimen of W. Herschel's handwriting. Sun has been showing symptoms of decay and several have been trying to observe it with limited success.
Of travels and family health.
Has been prevented from answering his letter earlier by increased illness. If he returns to town he will have pleasure in meeting H. C. Schumacher. Believes the pound must be made of bell metal. Thought JH was on his way to the Cape, but sees his letter was written from Slough.
Sending letter for him which was delivered to the Admiralty. Has had a letter from James South who is pleased with his reception in Copenhagen.
Sending three memoirs by his brother, two on Pantellaria and one on the forms of mountains. Would like a copy of JH's observations made in Sicily.
Has no intentions of making solar volcano theory public. Offers one more possibility for its validity. Pleased that Caroline Herschel is well and remembers him.
Introduces Mr. A. Perrey. Remarks on tourmaline. Astronomical matters.
Queries regarding a corroded clock face, and description of harvest bugs. Has an intermittent river in their district. Has now set up the Munich telescope and would be pleased to show it to JH. Does he want Amici's mirrors?
Describes a new form of sketch book, which may interest him. Encloses a paper from a friend, which can be answered by means of algebra, of which he himself is ignorant. JH's affairs were mentioned by Sir James Graham, who suggested that the Admiralty may be able to assist JH with a passage to the Cape.
Sends micrometer observations of stars suggested by JH.
The black broth that the Spartans liked must have been mushroom ketchup. Suggests way of obtaining a portable dome. Sends drawing and description of the harvest bug. Is pleased to hear of his projected Cape expedition. Is carrying out observations of the moon.
Sends JH a report by Mrs. Thomas Malthus on experiments relating to vision. Mentions T. Malthus's views of books on political economy by Thomas Chalmers and Richard Jones. Praises T. Malthus.
Acknowledging receipt of JH's book on double stars, which has been placed in the library.
Unable to spot Biela's Comet. Outstanding observing conditions allow WS to sight normally difficult objects. Makes suggestions concerning JH's rotating roof plans.
