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?
