| Title | Letter from Jean François Dominique Arago to Thomas Young |
| Date | 1818 |
| Description | No origin listed and no date [dated based on election of Prony, Poisson, Hauy], addressed to Young in London.
Presents thanks from [René Just] Haüy, [Gaspard de] Prony and [Simeon Denis] Poisson for being nominated as Foreign Fellows of the Royal Society, and asks for thanks to be sent to the PRS.
Lady Syer came to visit Mrs [Lucie Carrier-Besombes] Arago, remembers that a parcel was left by Mrs Ratcliffe and confusion around its intended recipient.
Arago has obtained a tracing of the hieroglyphs from [Edmé-François] Jomard for Young, the roll is too large to be sent by the post and is awaiting suitable passage.
Thanks Young for sending details on the wave theory of light which Arago supports ardently, saddened to see it getting a little more complicated. Light dispersion and polarisation are still to be explained properly. Hopes that Young can clear this up as his name will forever be associated with the theory of interference.
Closing the letter asking news on pendulum observations.
Von Humboldt is entering as Arago is finishing the letter and sends his compliments. |
