My dear Sir
Will you be so kind as to inform me whether the two hybrids which you gave me were brother & sister of the same hatch?1 I am glad to find that you have communicated to the Zoolog. Soc. the results of your crossing.2 This being so I will send a short letter with a few remarks to Nature.3 If you do not see Nature & will inform me, I will send you a copy if my letter is printed.
My dear sir | Yours faithfully & obliged | Ch. Darwin
