To Sven Nilsson 31 October 1
Down. | Bromley. | Kent. S.E.
Dear and Honoured Sir
I am very much obliged for your great kindness in sending me the reference about the Reindeer through Dr. Hooker.2 When next in London I will consult the work, and should be grateful for any further information from you.3 You will easily perceive that what I wish to ascertain is whether there is any relation whatever between the period of development of a character and its transmission to one sex alone or to both sexes.
I have much pleasure in enclosing my photograph, & if it would not cause you too much trouble I should very much like to possess one of you, as I have a collection of the photographs of eminent naturalists.4
With the most sincere respect | I remain yours sincerely & obliged | Charles Darwin
Thanks SN for the reference about the reindeer, received via Hooker.
CD wishes to ascertain whether there is any relation between the period of development of a character and its transmission to one sex alone.
