158. Four-rowed Ears. — The writer has occasional!)' found 

 in both flint and dent breeds, ears with only 4 or 6 rows (Fig. 

 84B). The occasional presence at the base of the ears of the 

 beginnings of additional rows, suggests that they are cases of 

 failure to develop certain pairs of rows. East and Hayes 

 associate the condition with the tendency commonly met with 

 in ears of 8-row flint breeds, to split at the base into 2- 

 rowed sections. Their investigations indicate that the tendency 

 to the abnormality is dominant to the normal condition.

fasciation, and lobing of the tip of the ear (Fig. 85A and B) are 

 not infrequently met with, and flattening and fasciation are 

 more common in some races than in others ; in the Transvaal 

 flattening is common in strains of Chester Comity. 



East and Hayes have studied the inheritance of this ab- 

 normality and find that it is a dominant character, alternatively 

 inherited, and that it is difficult to tell the pure normal ears by 

 inspection, but that they appear to breed true when isolated.

 branched ears (Fig. 86) are occasionally met with. Attempts
