From Robert Schlagintweit 25 September 1857
192, Jermyn Street, | London,
25th Sept. | 1857
My dear Sir,
It gave us great pleasure to receive your kind note of the 20th, and as I see that you kindly took interest in the communications, made by us lately in Dublin,1 I am very happy, to give you, as desired, some more particulars of the offspring of the Yak, the Chooboo, whom we really found fertile as far as to the 7th generation, a statement which is correctly contained in the Athenæum.2
As we were very anxious ourselves to have decided the question about the fertility of the Chooboos, we tried to collect as much information as possible; in all instances we met with fertile Chooboos, moreover not unfrequently even with castrated one’s.
I shall be most happy to give you more details, as soon as we shall have packed out & worked up our manuscripts & collections3
Believe me to be | dear Sir | Yours truly | Robert Schlagintweit
Gives CD further details of the fertility of the offspring from cross of a yak and Indian cow, the so-called chooboos, whose fertility he has traced to the seventh generation [see Natural selection, pp. 437–8].
