To Roland Trimen 12 February [1868]1

Feb 12
My dear Mr Trimen
I shall be very happy to put my name down for your brother’s book & he can hand over the enclosed paper to Hardwick—2
Since you were here I have become much interested on the relative numbers of the males & females of all animals.3 I am particularly anxious for other cases like that from Wallace which you gave me of females in excess;4 or to know that such cases are rare. If you can, I am sure you will aid me.
Do you give many instances in your book on S. African butterflies, of males in excess. I remember writing down one or 2 cases which you gave me—5
Believe me | yours very sincerely | Ch. Darwin
