CD regrets the trouble RO has had about C. G. Ehrenberg's parcel.
He is reading On the nature of limbs  with uncommon interest and admires the way Owen worked out the toes.
Also has read On parthenogenesis  with great interest.

My dear Owen
I am very much obliged, but am sorry, that you should have had the trouble about Ehrenbergs parcel— I enclose stamps which will I hope be convenient mode of payment to you.—
Yours most sincerely | C. Darwin
I am in the middle of the “Limbs” with uncommon interest— The manner in which you work out the toes strikes me as quite beautiful. Whoever would have thought that a great Cart-horse walked on four fingers!—
I read also with great interest some little time ago your kind present of Parthenogenesis
