Schedules time in London next week to cast two mirrors for 20-foot telescope. Details of mixture to be used for mirrors. Questions about casting process. Tells JH to consult 'Messr. Devey' for answers. Plans to visit Greenwich soon. Hand tremor makes writing difficult. Received letter from [Ragreneau?] inviting Herschel family to breakfast tomorrow.
