chestnut, or flea-bitten, there is scarcely a Horse which does not bear 

 vestiges, more or less pronounced, of dappling.

 on the flank disposed in slanting rows ; and Fig. 34 shows that on 

 the neck the dark colour tends to form bands.

Note that on the groin of both Horses of Fig. 38 the dapples 

 are being broken up into minute specks. 



When this occurs all over the surface, it probably gives rise to 

 what is called a 'flea-bitten' Horse, with either black or brown 

 specks.
