 Slime colour as the body or even paler. Blacks, as the naiiio 

 suggests, are black all over. Browns are intermediate betwcon 

 bays or chestnuts and blacks. Duns are palo yellow-brown or 

 fawn-coloured horses, typically resembling bays in having 

 the mane, tail, and lower parts of the legs black, but, apart 

 from the colour of the body, generally also differing from 

 them in having a black spinal stripe ruiniing from the mane 

 to the tail, those presenting this feature being known as 

 ** eel-backed " duns. Roans have the neck and body covered 

 with a mixture of white and black or white and red hairs. 

 A peculiarity about this type is the absence of white hairs, at 

 all events as a rule, from the head, mane, tail, and the lower 

 parts of the legs. Greys are mostly of two kinds, *' dappled " 

 when marked with a network of black, and " flea-bitten '' 

 when the black or brown is distributed as small specks over 

 a white ground. Greys pass into whites; but it is by no 

 means necessary to assume that whites are always exagge- 

 rations of the grey type. Analogy suggests that they may 

 be abrupt variations from bays or chestnuts. Finally, there 

 are piebald and skewbald horses blotched with white and 

 brown or black in varying projiortions. 



Now these types of colour seem to be reducible to three 

 categories : the first containing bays, blacks, chestnuts, roans, 

 and piebalds ; the second duns ; and the third greys and 

 the majority of whites. Blacks a|ij)ear to be melanistic and 

 chestnuts erythristic variations of bays with black points. 

 That chestnuts are "red" sports is attested by the colour of the 

 mane and tail being the same as that of the body or lighter; for 

 in all wild species of the horse family, like Kiangs, Gliigetais, 

 and Onagers, whatever shade of chestnut or fawn the coat 

 may be, the bulk of the mane and of the tail-tutt is black. 

 The frequency, too, with which chestnuts have a white blaze 

 and white '* stocking's " or " bracelets " shows a strong 

 tendency to albinism in this type. In these horses, as well 

 as in bays and blacks, albinism usually shows itself first by 

 a white spot, called the " star,'' on the hair-whorl of the 

 forehead. This may be the only white mark to be detected. 

 It varies considerably in size, and may spread over the 

 forehead and down the nose, to constitute the " blaze." 

 AVhen the blaze involves the end of the muzzle it is accom- 

 panied by a pink tinge of the lips, a sure sign of albinism 

 and certain evidence that the whiteness of this area in 

 domestic horses is not properly comparable to the whiteness 

 of the muzzle in Kiangs and Onagers, in which the area of the
