The Remarkable Achievements of
Scientists During the Last
Twelve Months as Represented at
the Annual Display of the New
York Academy of Science.

IOuTln annual eXnl DItlOn OF the New
York Academy of Science, which will
be held in the American Museum of
Natural History, New York, April 10
and 6, will witness a veritable world
of wonders. The past II months have
been especially rich in scientific pro-
gress and achievements, which for the
most part have been. withheld from
the public at large until a fitting OPP
portunity presented itself for their dis
play. This exhibition is intended to
show to the general public by ocular
demonstration just what has been ac-
complished in science during the past
year.
Every department of science will be
included in the exhibits, among which
will be Illustrations of recent progress
in anatomy, astronomy, botany, chem
istry, electricity, ethnology, archaeol-
ogy, experimental psychology, geolo-
gy, mineralogy, paleonthology, pho
Biography physics, photography and
zoology. In addition to the regular ad-
dress by President j. ]. Stevenson of
the academy, Nikola Tesla, the cleo
trician, will lecture on some novel
methods of producing Roentgen rays.
In the astronomy booth will be seen
immense photographs of the moon,
taken in the Lick observatory recent
ly for the purpose of composing what
will be. triumph both in astronomy
and in photography-the Lick atlas Of
the moon. Negatives of these photo
graphs will be shown, as we'll as plate
of the atlas. There will also be sew
eral reproduced plates taken with the
Bruce Photographic telescope at Ane
quipa, Peru, for the Harvard observa-
tory. Columbia college will exhibit
curious machine for measuring the va
rious characteristics of star photo
graphs, and in addition to some of the
wonderful micrometers in use in the
Yerkes observatory, the United States
Naval observatory and in the Univer-
sity of Pennsylvania, there will be
shown some of the work of that Won
derful ruling machine in Johns Hopkins
college which rules 100000 lines to the
inch.
The section on it is: Botany will in
clude curios from the vegetable world,
ranging al the way from the North
American observation-disclosures to a new
plum from Connecticut. One exhibit
will consist of the moulds of the bacter-
ial laboratory of the college of Physici-
ans and Surgeons, n. Y, and another
Will show the New Yorker some of the
bacteria he daily drinks in with his
supply Of Croton water Three of the
exhibits will consist of microscopic
slides of powder, leaves, roots and her
barium specimens illustrating some of
the official drugs and their adulterants
They were undertaken in the interest
of the revision committee of the United
States pharmacopaeia, to discover char
acteristicS by which each can be iden-
titled in a powdered condition, and they
include the roots of rio ipecac and Car
thagena iDacac. true and false mace.
eucalyptus, iaborandi, the stem and
root oe sassafras and others. Alto
gether there will be A exhibits in the
botanical section.
Chemistry is one of the inexact sci
ences, hence it is q fascinating pursuit.
The public will be interested in the
chemical section for many reasons.
Chief among them will be the number
of electrical furnaces on exhibition.
Moissan, the French maker of artificial
diamonds. is an honorary member of
the academ.. He will exhibit a large
collection of carbides and other prod
Ucts of chemical action as produced by
the heat of the electric furnace. Pro-
fessor r. Ogden Doremus of the col
lege of the city of New York, will ex-
hibit several styles of electric furnaces,
notably one which Moissan used dur
ing his demonstrations in this country.
A remarka BILE invention of the past few
months is an apparatus for the produc-
ton of acohol from acetylene. Chemi-
cally speaking, the process is simple.
Acetylene is formed together with mas
cent hydrogen by combining calcium
carbide. zinc and dilute sulphuric acid.
This results in the production of ethy-
lene, which, on coming in contact with
hot concentrated sulphuric acid, forms
ethyl sulphuric acid, which is changed to
alcohol and sulphuric acid on the addi-
ton of water. 1t is claimed that a 90
per cent alcohol can be manufactured
in this way for II cents a gallon.
Another exhibit will show some crys-
talline COPIED formed in electrolytic
tanks By gases carried by the atmos-
phere from Newtown creek, Long
island. to the copper works near by.
Art lovers will not fail to examine the
collection Of colored glasses to be
shown by Louis C. Tiffany, who will
illustrate scientific methods for the pro-
duction of lustres. iridescences and |
mass colors. Quite as gorgeous. per
haps, if not so delicate, viii be the col
lection OF new coloring matters dis |
covered this year. Even an artificial
oil of roses will be exhibited. Artificial /
come into common use, and which will /
be on show. A peculiar exhibit Will be
q method for collecting and analyzing |
the gases found in canned goods.
The word electricity is held by the
general public TO be the open sesame to |
all that is wonderful. Hence the cleo |
Lrical seers. Apparatus for the pro- /
1uction of electrical energy from car
bon without the application of heat, /
will illustrate the latest development |
in this department. A historical col |
ecion of incandescent lamps will show |
the Development of the lamp and its |
parts from the first crude /
forms to the present 300 volt high eff |
cheney lamp. Among the electrical in !
struments of precision will be q piece I
apparatus for determining the time |
elapsing between the make and break |
IF an electric circuit. 1t will be exhib- |
ted by students of Columbia univer- |
;ity. An induction coil throwing a |
spark 20 inches long should be an OBJ |
ect of great popular interest, mas |
much as the spectacle it presents is pic |
ureSque to the last degree. Another |
popular exhibit will be porcelain in /
;ulators from the Niagara Buffalo |
line, where they support |
wires carrying pressure of 10000 volts. |
from the historical point of |
view will be one of the two original |
induction coils used by Professor
Henry.
In the booths devoted to experiment
al psychology some really remarkable
Instruments will be displayed. There |
will be. for instance, an instrument for
'ecording the Dulsation of the eve.
There will be a regular pendulum used
o mark off exceedingly minute inter
yals of time. There will be set of |
