To George Cupples   29 May [1868]1

Down. | Bromley.| Kent. S. E.

May 29th

My dear Sir

I am much obliged for the information about the Terrier & for your kind promise to observe the size of your dogs with advancing age.—2

I have written to Mr Wright to thank him for his courtesy; & have asked him nearly the same questions as I asked you.—3 But I do not suppose I shall continue to attend to domestic animals, except so far as they illustrate points in the Nat. Hist. of wild animals.—4

Believe me | with my best thanks | Yours very faithfully | C. Darwin
