The substitution of this less convenient mode of notation
in Arithmetic was as natural not to say inevitable as
it is unfortunate: five is the number in the human
species five is the number of the fingers on each
hand the short and thickest finger distinguished by
the name of Thumb included; two the number of the
hands here then is ten the number continually
presenting itself to all human eyes here then was is
the elementary number: by the requisite number of
requisitions made of this number all greater numbers
are capable of being expressed.
have been known —
they would have adopted
the duodecimal mode.
Instances have sometimes been observed of human
beings provided with six fingers on each hand
instead of five: and had the lot function of giving names to
numbers fallen to the lot of any one of these so
extraordinarily gifted beings the result instead
of the decimal would have been the so much
more desirable duo decimal mode.
Extraordinary that designation
by single figures
should have stopped
at 9 — 10 being the
number of fingers.
A circumstance that presents itself as rather
extraordinary is that considering ten was the
number of the Archytype constantly in view
the practice of designating a number by a
single figure should have stopped where it was
No 9 instead of extending itself to No 10: a
number for which the same number figure that had
before been employed for designation of No 1
is again employed as a designation to the
other number by the help of the anomalous
figure 0 added to it
Thus stands the problem the solution does
not present itself as obvious.
