The weekly Floridian. [volume] (Tallahassee, Fla.) 1867-19??, 1891-09-12
The owner of a brownstone quarry
in Wisconsin has offered to the state

|
a solid monolith, larger that Cleopa
tra's needle in New York City. The
obelisk, when completed will weigh
400 tons and be the largest mass Of
brownstone ever quarried.
Mrs. Potter Palmer has called
upon woman sculptors to send de.
signs in the form of miniature
models of the sculpture work for the
woman's building. The designs
must be delivered to Mrs. Palmer's
office before Nov. Is next. One is
group of figures in high relief to
fill the pediment over the main en-
trance forty-6ve feet long at the base
line and seven feet in the center.
The second design of groups of stat
uary stands free above the attic
cornice, resting on the base, five feet
long, three feet deep and two feet
high, sixty feet from the ground.
These groups consist of a central
winged figure, standing about ten
feet high to the tip of the wings, and
supported by smaller sitting figures.
The compositions should be typical
of woman and woman's work in his
tory. Each design submitted must
be accomplished by an estimate of
cost, with full-sized plaster models,
delivered at Jackson Park, and the
authoress of the design accepted will
receive the contract for the execu-
tion of these full sized models.
The preparation of Colorado's ex-
hibit is progressing energetically.
Besides the mineral, agricultural and
educational exhibits, the fora and
fauna of the state will be shown in
great completeness. Already more
than 1000 specimens of plants have
been pressed nearly 200 varieties of
fruit have been duplicated perfectly
In wax, and more than 1000 species
Of insects have been mounted.
The Texas Worlds Fair Exhibit
Association is pushing, with great
energy, the work of collecting funds
for the states representation at Chi
cago. Sum desired is 100000, and
this has been assessed among the 245
counties as nearly as possible, &C
cording to population, on basis of
fifteen cents per capita. The Asso-
citation has headquarters at Fort
Worth and has distributed a great
deal of persuasive literature with ex-
cellent results. In one of its circular
letters appears the following /:
"Texas must not fail to participate
in an exhibition costing nearly fifty
millions Of dollars; one in which
every nation and commonwealth
10 the world will be represented, and
where she can show her vast
resources to fifty millions of visitors,
which means in five years a million
new people and five hundred millions
more money to circulate in our
state"
A magnificent microscope has just
been completed by the Munich
Poeller Physical and Optical Insti-
tute for the great Chicago Exposi
ton, at a cost of $3.50. 1t possesses
magnifying power of 1000 di
ameters. AS might be expected
electricity plays an important par,
in the working of this gigantic in.
strument, which, after inspection by
American citizens, is expected ate
give an impetus to the Munich mart
for scientific apparatus. The cleo
tricity furnishes and regulates the
source of light, which placed in the
focus of parabolic aluminium rehec.
tor reaches an intensity of IL 900 can.
die power. The electricity also pro
vides the means of an ingenious auto
matte mechanism for the centering OF
the quadruple condensers and illumi-
mating the lenses. There is an ar.
rangement for the exact control OF
the distance of the carbon point
The most important novel feature is
the cooling machine, which is indis.
pensable on account of the extreme
heat, l-43 calories per second, gener'
ated by the intense illuminating ar
rangement. A machine regulated by
a Helmhotz electric centrifugal reg
ulator provides the several microsco
pic and polariscopic systems of the
apparatus with fine spray of fluid
carbonic acid, which immediately
after its release from the copper yes
sci, in which it is held under a pres
sure of % atmospheres, becomes con
verted into gaseous matter, so in
tensely cold that only .OOOO7 gramme
of carbonic acid per second is re
qaired to give the result. The mag
nifying power of the apparatus with
ordinary objec:ives, as has beer
stated, is about IL 900 diameters, but
with the oil immersion it can be in
creased to 10000.
