Thus, for the fathers of F.R.S., 81 are recorded as noteworthy,
against 3.37 of fathers of the generality--that is, they are 24.1
times as numerous. For the first cousins of F.R.S. there are 99
noteworthies, divided amongst four kinds of male first-cousins, or
24.75 on an average to each kind, against the 3.37 of the
generality--that is, they are 7.3 times as numerous.

On this principle the expectation of noteworthiness in a kinsman of
an F.R.S. (or of other noteworthy person) is greater in the following
proportion than in one who has no such kinsman: If he be a father, 24
times as great; if a brother, 31 times; if a grandfather, 12 times;
if an uncle, 14 times; if a male first cousin, 7 times; if a
great-great-grandfather on the paternal line, 31/2 times.

The reader may work out results for himself on other hypotheses as to
the percentage of noteworthiness among the generality. A considerably
larger proportion would be noteworthy in the higher classes of
society, but a far smaller one in the lower; it is to the bulk, say,
to three-quarters of them, that the 1 per cent. estimate applies, the
extreme variations from it tending to balance one another.

The figures on which the above calculations depend may each or all of
them be changed to any reasonable amount,
