EXTRAORDINARY CALCULATOR

In a report of the proceeding at a recent meeting
of the members of the Institute of Actuaries, given in
the Post Magazine, the following account is furnished
of a German, at present residing in London; whose cal-
culating powers seem to outbid those of the celebrated
George Bidder :—"The remainder of the evening was
occupied by the appearance of a German gentleman,
named Daze, whose extraordinary talents fbr calcula-
ti .n, and
.the facility with which he performs the
most tedious arithmetical operations, and answers the
questions with equal ease, either verbally or in writ-

ing, are so remarkable, as to elicit the wonder and
admiration of every one who hears or sees him. His
answers are given with almost the same rapidity that
the listener can write down the result, allowing
nothing for the time spent in computing. The first
question asked him was the product of a number, con-
sisting of five figures, by another number of five
figures, and the correct answer was given almost iestan-
taneously. His friend, who acted as interpreter for
him, stated that he had the most singular power of
telling at a glance a great number of objects thrown
upon the table—as fir instance, the total num-
ber of marks on dominoes, even to one hundred or
more. To test this quality, the balloting balls,
which hail just been used for the admission of new
member:, were thrown from the box looie upon the
table, and Herr Daze, after taking a single glance,
and then turning away, declared the total number to
be 68, which proved to be correct, when the balls were
counted and returned to the box. It should be re-
marked in this case that some were lying much
nearer together than otheta, and that they would
appear to an ordinary spectator to be so confused
as to puzzle even an experienced calculator how
to avoid reckoning some of thorn twice. He
then gave the product of two numbers to twelve
Sgure::, multiplied it by 7, and repeated the lat-
ter product backwards without an error in any figure,
He was then asked the cube of 457, which watt cor
rectly given, 95,433,993, almost instantaneously. He
will divide a number by another, consisting of two
or three figures, and will write down the answer at
once, in one line, without any apparent intermediate
process. In as rapid a manner he gave the factors to
7,421, namely, 41,181 ; but it would take up too much
time to state all the surprising proofs of this singular
felt of calculation. We may merely mention, as one
instance, that be multiplied a number, consisting of
12 figures, by another number of 12 figures, and gave
the product correct in one minute and three-quarters."
