 breeds true. That it has long been domesticated, there can be little doubt ; and 

 this might have been inferred even from the circumstance that its young are not 

 longitudinally striped." From a study of its skull, Professor Nathusius regards the 

 masked pig as nearly allied to the Chinese breed ; but, as Darwin remarks, " if this 

 be really the case, it is a wonderful instance of the amount of modification which 

 can be effected under domestication."

 simpler structure, the last in the lower jaw having the third lobe much reduced 

 in size. The tusks are scarcely larger than those of domestic pigs, and the 

 snout is unusually elongated. On each side of the face immediately below the 

 eye there is a large swelling, due to the great development of a ridge of bone

 from South to Central Africa, has the hair of a greyish brown colour, and no 

 pencils of hair on the ears. It generally frequents thick forest, although 

 occasionally found in thorny bush and among reeds in the river valleys. Mr.
