has a grey foal resulted; while, from 35 matings of dun with grey, 10 grey 

 foals are recorded. These 35 foals were 1 chestnut, 3 hlack, 5 bay, 1 brown, 

 15 dun, and 10 grey. A very striking case might be quoted from Clare 

 Island, off the west coast of Mayo. A dun pony sire stationed there for a year 

 left about 50 foals, and, according to Mr. Garvey, the Department of 

 Agriculture's ofBcer now on tlie island, " there were no grey ones, except one 

 from a grey mare." The statistical evidence can be confirmed directly by a 

 few individual eases. A black stallion, The Monk, and a grey polo pony 

 mare, Sibyl, had a dun foal. Hermit' ; Old Highland Laddie, grey, and a 

 grey pony mare had a dun foal- ; Shooting Star, a grey pony sire, and 

 Bleddfa Periwinkle, a dark bay mare, liad a dun roan foaP ; The Chief, a 

 black Clydesdale, and Grey Tess, a Clydesdale mare, had a dun foal, Nell of 

 Haplands* ; and there is the case quoted in the previous paper from Professor 

 Cossar Ewart : "in one specimen of this variety^ met with in Perthshire (a 

 14-hands grey mare which produced a dun colt to a grey garron) the profile 

 is straight . . . . "" There are two eases quoted by Dr. Crampe in the paper 

 referred to in the foot-note on p. 193. A grey horse, Sterling II, sires two dun 

 foals, one from a black mare, Nacht, the other from a brown mare, Galante.' 



There now remain only the relative positions of dun and brown. In 

 the Thoroughbred, Polo, and Clydesdale stud-books only 23 matings of 

 brown with dun have been found where the colours of the foals are given : 

 but in no case can the gametic composition of the parents be worked out. 

 The colours of these 23 foals are 1 black, 3 bay, 10 brown, and 9 dun; but 

 these, although suggestive, do not admit a clear inference. Evidence on the 

 point has been sought in the west of Ireland, where there is still a very 

 considerable number of dun ponies. Mr. Michael Scully, one of the Depart- 

 ment of Agriculture's officials in County Mayo, reports on some dun stock in 

 that county, and mentions two dun mares which have had brown foals to 

 black sires. One of these mares had three foals dun and one brown, and the 

 other mare had one foal dark brown and the other black to black sires.* 



But the fullest evidence comes from Clare Island. Indeed, it is sufficient 

 to place dun in position with regard to every colour.
