Regarding the change of ownership and policy of the Edinburgh Philosophical Journal. Would like a paper from him for the first number. Marked 'Private.'
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.'

Praises old Edinburgh Philosophical Journal. Promises to send DB some materials for publication.
JH's theory of colors. Edward Troughton has DB's instrument one-third completed. When will DB want JH's encyclopedia article on 'Variation'?
