Dear Mr. Poincaré,
I was glad a fortnight ago to receive your New Year card, and had kept it as a reminder to send my own in return, when yesterday I received your beautiful volume “Théorie Mathématique de la Lumière.”11endnote: 1 Poincaré 1889. It contains a great deal of most interesting reading for me, and I thank you very much for your kindness in sending it to me. With all good wishes to you for the New Year.
I remain, yours very truly,
