Thanks for MS's works, communicated through [Picot] Tremblay. Worries that JH has insufficient time and lags behind in the physical sciences. Comments on ideas put forward in 1824 by JH and discussed by MS. Has found MS's name connected with suspension bridge over Rhone River.

Apologizes for not having seen JH's paper on spectra of colored flames and thus having overlooked JH's prior claims [see JH's 1861-7-21]. Will try to make amends.
