tation being 10,000, 1000, 100, 10, I. Every direct ancestor in 
the zth degree admits of being specified by a particular number, 
consisting of z + 1 places. e two parents are IO and II, 
grandparents 100, IOI, IIO, III, and so on. Literally the three

In the ancestry the even numbers mark males, the odd, females. 
Each term carries on its face every step in the descent. Instead 
of saying, for instance, B was father’s mother of A, we say B 
was 101 of A. If the father’s-father’s parents of C were the 
-mother’s parents of D, we say the 1000-1 of C are the 110-1 of 
D. The case might have been one of half blood, say by the father’s 
side, then the 1000 of C would be 110 of D. Translating the 
inary into common figures, we have:
