side. What this clearly means is that at least one-half of all 

 the dam's ancestors, in the third and higher ancestral genera- 

 tions, are, identically the same aniinals as are ancestors of the 

 sire. The next entry in Table 5 indicates that in the fourth 

 and higher ancestral generations at least f of all the dam's 

 ancestors were the same individual animals as were also ances- 

 tors of the sire. One-half of them were the same before the 

 reappearance of St. Lambert's Rioter King. He makes up the 

 additional ^ of the dam's ancestry.

From these tables it is obvious that a very considerable portion 

 of the inbreeding shown in the pedigree of King Melia Rioter 

 14th arises from the fact that his sire and dam were closely 

 related. Furthermore, both sire and dam are closely inbred 

 in their own lines. The curve of total inbreeding in this case 

 is shown in Fig. 51, along with the curves for continued brother 

 X sister, and parent by offspring.
