Dear Madam

Your observations and experiments on the sexes of butterflies are by far the best, as far as known to me, which have ever been made. They seem to me so important, that I earnestly hope you will repeat them and record the exact number of the larvae which you tempt to continue feeding and deprive of food, and record the sexes of the mature insects.

Assuredly you ought then to publish the result in some well-known scientific journal.

I am glad to hear that your observations on Drosera will be published. I have attended to this subject during several years, and have almost M.S enough to make a volume; but have never yet found time to publish it.

I am very much obliged for your courteous letter and remain dear Madam

Yours faithfully

CH. DARWIN.
