To V. O. Kovalevsky   18 September [1872]

My dear Sir

Thursday (tomorrow) will suit me excellently.— As my head always fails me in the afternoon (when I have to lie down) will you be so kind as to come by the Train which leaves Charing X at 2^o. 35’ & reaches Orpington at 3^o 11. There is a return train which leaves Orpington at 6^o 52’, & we can send you to the Station, so that you w^d. have to leave this house at 6^o, 5’ or 10’.— There is another train at 8^o. 24’ but then you w^d not have time to eat your dinner here.—¹

Yours very sincerely | Ch. Darwin
