The data now brouglit together come chiefly from stud-books, but also 

 from animals not entered in stud-books. But in neither case is it possible 

 to find many instances of individual animals having a large number of 

 progeny — and such instances are the most desirable — because dun has been 

 an unwelcome colour in all British breeds, not only in stud-book times but 

 before them, and, so, has not been bred from freely. Some breeds, as, for 

 instance, the SufPolks, Yorkshire Bays and Coach Horses, and Shires, have no 

 duns — or at any rate only very few — in their stud-books. The dun colour, 

 which had been receding northwards and westwards, had left the east coast 

 before these breeds were entered in stud-books. Dun entries occur, however, 

 in all our other stud-books, namely, in the Shetland, the Clydesdale, the 

 Hackney, the Polo and Riding Pony, and the Thoroughbred. The last 

 contains a comparatively larger total number of entries concerning dun and 

 also the largest number of individual dun animals leaving a fair number of 

 progeny. Curiously enough, these individual animals, with one exception, 

 the Gower Dun Barb, belong all to one family, the explanation being no 

 doubt that this family had racing ability, and so was bred from for a few 

 generations in spite of its colour. The other dun and presumably dun 

 animals which left either only one or two recorded progeny or none at all 

 are these : — the Darcy Tellow Turk, presumably a dun of Charles the 

 Second's time which left two sons, viz.. Spanker, a bay, and Brimmer, whose 

 colour is not given ; Lord Oicford's Dim Arabian, imported early in the 

 eighteenth century, which left two daughters whose colours are not given ; 

 ThioaUes's Dun Mare, a daughter of the Akaster Turk, living early in the 

 eighteenth century, which left a son and a daughter whose colours are not 

 given ; the Northumberland Golden Arabian, presumably a dun, which left 

 a daughter, Leda, whose colour is not given ; and three others which left no 

 recorded progeny, viz., Morgan's Dun, a dun colt by His Majesty's (George the 

 Second) one-eyed grey Arabian out of young Kitty Burdett, and a dunfiUi/ 

 by Gregory's Arabian out of Miss Middleton. None of the foregoing is 

 responsible for a dun entry other than its own in the stud-book. In addition 

 to these there was a filly by Young Cade out of Miss Thigh (1763 ?) entered 

 as dun ; but it is doubtful if she was dun, for none of her nine foals was 

 recorded as such. 



The following table shows in detail the results of the matings with the 

 dun family above referred to, and also with the Gower Dun Barb.
