Vol. 6 and 7 of F. W. Bessel's observations. Did DB receive JH's paper?
Letter to [Edinburgh Philosophical] Journal calling attention to 1809 article by [Paul] Erman of Berlin, which some say anticipated JH's 1824 Bakerian lecture on 'Motions produced in fluid conductors when transmitting the Electric current.' JH compares both papers, admits Erman's priority on some theoretical points but claims originality for JH's experiments.
JH's theory of colors. Edward Troughton has DB's instrument one-third completed. When will DB want JH's encyclopedia article on 'Variation'?
Praises old Edinburgh Philosophical Journal. Promises to send DB some materials for publication.

Asks DB to sign a certificate for the candidature of William Ritchie for admission to R.S.L.
Sending DB a draft of a paper; comments on quality of a chromatic lens (that of [Charles] Tulley's telescope using Pierre Guinand's glass).
Having now learned that the offensive article in the Edinburgh Review was by DB [see DB's 1831-12-1], JH writes in surprise that DB could have written what he did, and requests that JH's letter [see JH's 1831-11-25] be returned unpublished. JH will decide how to proceed.
Is pleased with Mr. Johnston's reply. Regarding a figure used by JH in his paper and its true significance. Is not certain yet whether to join the B.A.A.S.

Regarding DB's views on support for JH in the presidency of the R.S.L.

Thanks for his letter regarding the dioptric lights. Gives his own views as to their importance.
