From W. E. Darwin 11 November 1871
Nov 11. 1871
My dear Father,
I send you a note from Capt Jones with answer from his father, who I believe farms at Bala.1 If this is not enough, I will write again to him.
I have not received any proofs from Murray for some days, I suppose there is some delay.2
Your affect son | W. E. Darwin
What is the meaning of Prof. Cope’s “origin of genera” in Nature3
[Enclosure]
Chester
8. 11 71
My dear Darwin.
My governor4 writes to me. “Of course Castration produces a great effect on the horns of Sheep—as the horns do not grow to so large a size, or so strong— The lambs, are castrated when they are from one to two months old—& the older they are before they are castrated, the larger & stronger will become the horns—& the rule applies to cattle the younger the calf is castrated, the finer (i.e thinner) becomes his horn5
Is this sufficient for your purpose, as I can get you what evidence you like— I do not know whether you want any data as to Ewes horns?
Perhaps you would like measurements length & girth &c taken.—if so let me know, and, I can get these carefully done for your father
Sincerely yrs | R. O. Jones
