[22.03.1889]11endnote: 1 Postal stamps: Paris Bd Saint-Germain, 22 March – Baltimore, 1 April 1889.
Mon cher ami,
Je vous adresse sous pli recommandé le mémoire dont je vous ai parlé.22endnote: 2 See Poincaré 1890, which he mentions in his letter of 30 January 1889 (§ 4-22-30). Veuillez m’en accuser réception.33endnote: 3 Craig acknowledged receipt on 8 April (§ 4-22-32).
La fin tourne un peu court, mais de tristes soucis m’empêchent de m’en occuper pour le moment; je pense y revenir d’ailleurs plus tard.44endnote: 4 Among Poincaré’s worries were a priority claim by the astronomer Hugo Gyldén, about which Poincaré wrote to Mittag-Leffler on 5 February 1889 (§ 1-1-80). At home, Poincaré’s wife Louise was in the early stage of pregnancy with Yvonne, their second child, and this may have been cause for concern.
Votre ami dévoué,
Poincaré
