was the first introduction to the Parish
ans of Jacques maud, one of the present
novelties OF the town.
This acrobat in figures is not a French
man by birth, though naturalized citi-
zen. He was born in Piedmont, his par
ents being the poorest of peasants.
Inaudi began life by tending sheep on
the mountains. From sheep keeping he
passed to vagabondism, wandering from
town to iowa showing pet dormouse
whenever he could get an audience and
living by the pennies mis- spectators threw
him.
In the course of his strolling maud
crossed from Italy to France, and pres
entity made a discovery which turned the
whole course of his life.
Wandering into a restaurant one day
he saw the proprietor puzzling over a
sum. He had written it down on top OF
the table and was doing his best to solve
it, but it would not "come out right. -
maud watched him few minutes, then
he ventured to speak:
s'If you wish, sir, I'll do that sum for
you. Read me the numbers. -
The Iuan read them aloud, and in an
instant, to his great establishment and
that or the spectators who had gathered
about, maud gave the correct answer.
Pennies We're showered upon him, and
from that day he became AN exhibitor of
numbers instead of animals.
His method of working is we'll shown in
the picture accompanying this article.
Standing with his back to a blackboard,
| Inaudi listens attentively to the ques-
tons which his audience proDounds. His
assistant writes on the board the figures
given, and they are hardly down before
the calculator calls out the answer.
For example some one asks him to
multiply 653x9S2; instantly, almost, he
answers 641, 246.
He viii subtract, divide, square and
cube numbers, extract roots, all with the
same ease, and never seeing the figures.
Frequently the sums are very complex.
| Here is one propOunded at the Sorbonne:
TO find number of places, the sum of
which is 60, the sum of the number in
| place of hundreds and OF that in the place
of thousands is equal to the figure in tens
| place, and the sum OF the figures occupy
| ing the tens and thousands places is
equal to the figure standing in unit S
place. If you reverse the number it is in :
creased by S,0S2-
maud gave the correct answer to this
/ in about three minutes-1, 739.
He often does two problems at the same
time, talking as he works them. Thus,
if asked to cube a number and to tell
what day of the week a certain date, as
March Il, 1922, came on, he will answer
| March II, 1922, came on Monday A
person born on that day has lived SO
many hours and SO many minutes. The
cube Of is SO and So" And the an
swers are always exact.
Simila~ TO this simultaneous calcula-
ton is his ability to count the beats of
two metrometres, going at different
speeds. He will tell how many ticks each
gives in minute.
Nor can he be caught with impossible
problems. This was tried at one of the
examinations before the Partisan savants,
but after a moments reflection on the
question proposed, he said: 1.-THE an
sWer is negative; no such problem can ex-
ist. -
Der OF forty two places read to him rap
idly. That this is remarkab BILE feat one
sees if he attempt to write down number
of forty-two places, or, more clearly still,
| ii he attempts to repeat after a reader
large numbers read rapidly.
! Another popularity of this calculating
acrobat is the persistency with which
these figures stay in his head. He will
| repeat problems dictated to him after the
| lapse OF several days.
| maud is an intelligent little fellow,
| though in no particular, save figures, at
all remarkable. In appearance his only
popularity is the height and breadth OF
his forehead.
! flow does he make his calculations?
| That is what the scientists of Paris have
been trying to find out.
maud explains very clearly his method
of working problems, and it is always an
| original and ingenious method. For
example, in multiplying he goes from
! LETT to right. Take the example quoted
above-to multiply 653x9S2. His method
| is as follows:
