Feb. 25th

Dear Sir

I am very much obliged for your kindness in sending me the results about the sexes of Trout.—1 I am anxious to ascertain approximately the proportional numbers of the sexes in any animals; but there are so many causes of error that I fear I shall not succeed.

With my best thanks for your information I beg leave to remain | Dear Sir | Yours faithfully | Charles Darwin


See the memorandum from Henry Lee, 21 January 1868 and n. 1.
