Has been making optical experiments. Hopes to see JH in the Spring. Hopes JH will be able to observe Encke's comet this year.
Will he be visiting Cambridge this Spring?
Observations on the various ways of measuring angular positions (of double stars). Opinion on JH publishing his catalogue of nebulae. Remarks on the low standard of astronomical observations in England compared with the Continent.
Observations on the gravimeter.
Requests that the engravings for the catalogue of nebulae be speeded up. Further observations on the gravimeter. Observations on W. R. Hamilton's experiments on biaxial crystals using A. J. Fresnel's wave surface theory.
Requesting a copy of G. A. A. Plana and Francesco Carlini's 'Lunar Theory.' Further remarks on the practicability of the gravimeter.
Is trying to clean up JH's nebulae observations preparatory to leaving for the Cape; comments on communications from F. G. W. Struve about double stars.
Is grateful for GA's encouragement to prepare JH's nebulae observations for publication before leaving for the Cape; it now seems clear to JH that he cannot leave before 1833; JH has had further communications from F. G. W. Struve about double stars [see JH's 1832-5-4].
