Has been unable to answer his letters due to the King's visit. Refrained from writing on hearing of the death of W. Herschel. His paper on the absorption of light will appear in the next number of the Transactions of the Royal Society of Edinburgh. Comments on this. Grateful for any astronomical news. Advice welcomed on memoir of W. Herschel.
Accompanies a paper JH was submitting to the Royal Society of Edinburgh. Discusses motion of light rays in Apophyllite and various optical writings of DB.
Sends JH's 1823 paper 'Absorption of Light by Coloured Media' to Royal Society of Edinburgh. Approves DB's illustration of polarized light in mineral apophyllite. Corrects DB's quotation from JH's letter regarding crystals observed on Mont Blanc.
Sends circular of F. W. Bessel's 'Declinations.' Sent paper on 25 July for Royal Society of Edinburgh, similar to DB's paper outlined in previous issue [of Edinburgh Journal of Science]. Argues for continuity of color spectrum versus 'per saltum' transitions.
