The Improved ThsodoIite,


most noted step.or era in mathemat-
ical discovery, has just been COM
pletsd, and is now ready TO be ex
hibited aad will attract the atten-
tion OF the scientific world.
There were just two pre- eminent
steps or eras in mathematical dis
covery and invention of world re-
novned mathematical principles un-
til this astonishing discovery added
the third. The first great step was
taken bp Pythageros, Grecian phi
lOsspher and mathematician, whose
powerful discoveries made Grecian
history famous and his own name i'm
mortal. The second was by. Euclyd,
the founder OF the great mathensti-
cal school at Alexandria, more than
three hundred years before Christ.
He was the famous author of the
47th proposition in Euclyd, respect
ing the square of the hypotenuse
which made his name as imperisha-
BILE as the ages.
The third and greatest of them in
avery point of compsrl son In the
merit of mind to conceive greater
principle and an inventive genius to
supply the instrument to apply it
has been reserved to Mr.. j. b. Eau
cette, Of this place. There is no
doubt but that the mathematical
world is on the era OF greater sur
prise than it ever had before, because
there is no doubt but that the sys-
tenn Of geometrical and astronomical
calculations is on the eve Of a COM
plete revolution.
What the significance of the Fau-
cette Quadrageodelite will BEGAN be
determined only when the world re-
allies the discovery OF principle
and instrument that abolishes calcu-
lations by signs and cosigns and log
arithms, which in their very nature
are only approximate, and introdu-
ces instead calculation based on the
square and absolutely correct.
This ingenious instrument as it
sets before you may be briefly des-
cribed as follows
1t is composed of two quadrants,
mounted on an old fashioned sur
veyors compass. These quadrants
were cut frsm II inch perfect
squares of brass plate, and are fas-
tened tothe..side standards Of the COM
pass. They contain the graduation of
degrees, and are also graduated as to
indicate the relative proportion OF
the circle to the square. One OF
these quadrants Is attached TO the
right arm OF the compass vertically
and 10 for the purpose OF dcnotlng
altitude and depression.
The other is horizontal, and fas-
tened to the left arm OF the compass
and to the vertical quadrant, but so
adjusted as to be elevated or depress-
ed at will, marking any degree not
ed on the vertical quadrant. This
horizontal quadrant is supplied with
q focus bar attached to its heel at
the right hand of its base and mount
ed with a telescope, by means Of
which observations are made, and
which is operated from the focus bar
TO the tangent by means of an arm
fastened in the center OF the radius,
the focus bar indicating the dspar-
ture. Set the instrument before
you. Take you observations on the
object 10 which you want to know
the distance, from the tangent of the
circle al the left, revolve the teie-
scope round to the focus bar, and
bring it into position, then catch the
bar At the farther end, and move 1t to
the left until you focus the object.
Note the departure on the quadrant.
Then divide the square OF the radi-
us by the departure and you have
the distsnce to your object. This Is
the simple process. 1t will be seen
that it's calculations are all based on
tho square. completely revolutioniz-
ing the present mode of calculation
by signs and cosigns, and reducing
the hitherto obstruse problems to
supple proportion. If it proves the
success IL necessarily must, 1T is GER
tain TIA at nc discovery In the scien-
tiffc world will eclipse it's fame or
transcend its usefulness.
This remarkable invention is the
result Of fourteen years OF constant
thought. The ides was first sug-
e.sted to it's author In 1871 by hear
ing soldiers talk of the dehcisncy
