FINE RESULTS SHOWN
SCIENTIFIC EXHIBIT OF CAR
NEGIE INSTITUTION ON VIEW.
First Public Exhibition in New
Building on 18th Street-Some
Remarkable Experiments.

For the first time Yesterday afternoon
exhibits of the several scientific depart
nlents of the Carnegie Institution OF
Washington We're placed on public view
| in the institutions new building, 18th and
p streets. Attendants acted as guides
and conducted the visitors through the
| different exhibit rooms explaining the
various, phases of the scientific work The
| exhibition is to be in progress from :
until $50 o'clock this afternoon and to-
| morrow.
Several hundred persons, chiefly from
| the scientific bureaus of the government
| and local educational institutions, avail
ed themselves of the opportunity to call
at the institution building yesterday aft
| ernoon. Much OF the display is confined
to photographs and drawings.
The most complete displays were from
the department of experimental evolution,
located at Cold Spring Harbor. Long Is
land. N. Y, the Solar Observatory at
Pasadena, Cal, and the division of pub
locations IN this city. Remarkable results
were shown from experimental evolution
tests in the cross breeding OF birds and
mammals and cross culture of plants. In
the former stuffed specimens We're dis
played Of agoutis. guinea pigs. rabbits,
rats and mice for three generations and
more after the first trial experiment, re-
sulting in astonishing cOlOringS and
sizes. The same results, but to a more
apparent degree, were obtained from
poultry experiments. The results of tests
among canaries. Java white sparrows and
flowers were of such nature to APP
peal to the scientist.
Remarkable Photography.
A number of Photographic plates and
photographs Of the sun, taken at different
periods of the year and portraying re-
markable phenomena of that celestial
body. were on exhibition. Several of these
exhibits will undoubtedly play promi-
nent part in further Investigations of the
solar system. Two three Photographic
plates are remarkably clear in displaying
the general character of sun spots. FIX
hibits of a similar nature of the moon
and different stellar systems were also
shown.
In the division of publications the re-
suits of practically every experiment at
tempted by the institution were exhibited
In book or pamphlet form. In addition
to these scientific works for the pur-
pose of reference were included among
the exhibits.
The displays from the departments of
marine biology and botanical research
were incomplete, and consisted chiefly
of photographs of the experimental sta
lions and their equipment. Several pro-
tographs of the palOlo. a marine worm,
seen only in the waters of Florida in
the last quarter of the July moon: plant
parasites from the desert regions OF
America, and tests showing the aridity
of the southern United States through
water evaporation were the most inter-
esting.
Magnetic Exhibit.
The department Of terrestrial mag
netism exhibits was confined to photo
graphs of the institutions non-magnetic
ships the Carnegie and Galilee; their
equipment and several instruments
among which were two magnetometers
and liquid compass and defector, in
vented by employees of the institution.
Several charts showing the location of
magnetic elements in the oceans were
also displayed Charts giving the re-
suits Of tests among metal workers and
bicycle riders and alcoholic experiments
were on exhibition from the institutions
nutrition laboratory.
The exhibits confined to the second
floor were Systematically arranged un-
der the several department heads. The
building was tastefully/ decorated with
palms, which added to the beauty Of its
elaborate detail. Many of the visitors
inspected the board of trustees room and
the assembly hall on the first floor, both
of which are appropriately and artistic
ally furnished.
