Dear Mr. Darwin,
Pray accept my warmest thanks for your most kind and unexpected present—as well as my hearty congratulations on the completion of this work, to which I, in common with so many others, have long been looking forward—1 I have also to offer you my congratulations on the highly honourable place taken by your son in the late Mathematical Tripos—2 He is a living proof of your beautiful theory of “descent with modification The talent is inherited but applied in a different manner—
I have just glanced at your introductory chapter and am delighted to see that you promise us two more works—3
Believe me | Yrs. very truly & obliged | Alfred Newton—
Thanks CD for present [of Variation].
