 one is defective. In that case, a male with a four-point comb 

 would be mated to females with five-pointed combs if possible. 

 The results may not be as gratifying the first year, but later 

 they will be much more so, if the purpose is to establish a strain 

 in which a five-point comb is a well established feature. If the

 narrow, that followed the head too closely with those that were 

 elevated too much, too thin combs with too thick, bases that
