pigmentless skin— generally characteristic of the larger 

 areas, while its mar-in is underlaid bv hlack skin, but 

 urrry the reverse. In some instances, however, the pig 

 mentless skin and hair areas exactly coincide. The hoof 

 of the white foot of a horse or cow is generally white, 

 that of the dark foot always black; however, quite often 

 a white patch or streak will extend to the hoof and then 

 come to an abrupt end, the hoof continuing in a vertical 

 line the same pigment possessed by the skin immediately 

 underneath the lighter hair patch giving rise to the hoof; 

 thus the hoof is as dark or darker, but never lighter, than 

 the hair patch immediately above. In spotted horses it 

 is observed that a white coat spot crossing the mane will 

 sometimes whiten it, while in other instances it will not.
