3-15-9. George Howard Darwin to H. Poincaré
Dear Monsieur Poincaré,
I learn that the University has offered you the degree of Doctor of Sciences and I now write to say that if you propose to come here on June 13th (?) to receive the degree it will give us much pleasure if you will stay with us. If Madame Poincaré would like to accompany you, my wife and I would have much pleasure in receiving her also.11Poincaré agreed to accept the degree in person, but declined Darwin’s invitation to stay with the Darwins, by letter to Darwin on 22.05.1900 (§ 3-15-10).
