crossing, obliterating varieties, on which, as you know, I have 

 been collecting facts for these dozen years. How awfully flat 

 I shall feel, if when I get my notes together on species, &c, &c,

Down, Nov 5th [1854]. 



My dear Hooker, — I was delighted to get your note 

 yesterday. I congratulate you very heartily,* and whether 

 you care much or little, I rejoice to see the highest scientific 

 judgment-court in Great Britain recognise your claims. I do 

 hope Mrs. Hooker is pleased, and E. desires me particularly 

 to send her cordial congratulations. ... I pity you from the

 Farewell. My dear Hooker, your sincere friend, 



C. Darwin.
