To William Francis   Friday1

Friday

My Dear Francis,

There is a memoir by Savart on the vibration of plates of wood crystal &c in the Annales du Chemie et de Physique2 which I am extremely anxious to read – it stands in vol. [40] – you would confer a great favour on me if you would send it to me by rail as soon as you can – dont pay the carriage – or if you do be good enough to set it down against me – 3

Sincerely yours | J Tyndall

I hope the books I sent you4 arrived safely

[12 March 1852]: dated to March 1852 by an entry in Tyndall’s Journal: ‘I was most anxious for a memoir of Melloni’s and for one of Savart’s and Francis has sent me a number of the Scientific Memoirs unexpectedly containing both’ (18 March 1852, JT/2/13b/561). We assume that Francis sent the translations on receiving this letter. The Friday on which Tyndall made the request is therefore probably 12 March, with 5 March possible but unlikely.

memoir by Savart ... Physique: Félix Savart, ‘Recherches sur l’élasticité des corps qui cristallisent régulièrement’, Annal. Chim. et Phys., 40 (1829), pp. 5–30. Tyndall’s letter is hurried: he mixed French and German in identifying the journal and the handwriting is difficult to decipher. The translation, sent by Francis, was ‘Researches on the Elasticity of Bodies which crystallize regularly’, Scientific Memoirs, vol. 1 (1837), ed. Richard Taylor, pp. 139–52 and 255–68.

set it down against me – : against what Francis paid Tyndall for translations for the Phil. Mag.

the books I sent you: not identified.
