Sends [William Whewell's] 'Isle of Sirens' and an acknowledgement to it in 'skimble skamble Hexameters.' Is eager to receive solar photographs and will send others by Professor [George?] Morton.
Is working on a compilation of the measures of double stars. If [Rudolf] Wolf's period of 11.11 years is correct, why should 1810-11, a minimum, mark the first observations of solar spots?
Discusses discrepencies between his observations for September and WS's photograph. It seems the new spots result from Jupiter being in opposition.
Describes the similarities between JH's sketches and WS's photographs of sunspots. Has greater faith in own observations. Wishes WS would add Julian dates. Sends Professor [George?] Morton's photographs.
