Dear & Honoured Sir

I thank you sincerely for your great kindness in having taken so much trouble to oblige me.

The information which you have sent is exactly what I wanted, & will be of the greatest value to me.1

I am very proud to be able to add your photograph to my collection of eminent naturalists.2

With my best thanks & the most sincere respect | I remain my dear Sir | yours truly obliged | Charles Darwin

In his letter of 31 December 1868 (Correspondence vol. 16), Nilsson had sent CD information on the age at which reindeer acquired antlers and on the possession of antlers by both sexes. In Descent 1: 288, CD cited Nilsson for the information.
Nilsson had enclosed his photograph with his letter of 31 December 1868, but it has not been found in the Darwin Archive–CUL.
