take photographs and make spectroscoplc
observations during the eclipse. The
observation by the representatives of the
Smithsonian Institution, twenty in num-
ber. were under the direction of Prof.
Chas G. Abbott
Here the largest camera known was
especially constructed to photograph the
inner and outer corona of the sun This
camera was one hundred and thrty-five
feet in length using lense twelve inches
in diameter, making an exposure 30X30
Six exposures were made by this instru-
ment during the totality of the eclipse.
which lasted ninety-two seconds. In ad-
dition TO this, there was another ele-
waited camera thirty-five feet in length.
With this instrument eight exposures
were made. Exposures were made
through a large double camera, eleven
feet in length, for the purpose of photo
graphing any planets between Mercury
and the sun. The location of the planet
Vulcan, the actual existence Of which is
not known, but which is supposed to be
Immediately near the sun, was sought to
be discovered.
The observa tons at the Yerkes station
were under the direction of Prof Geo. e.
Hale director of the Yerkes' observa-
tory. Here three objects were in view;
/, to photograph the corona on large
and small scale; >, to photograph the
spectrum of the edge of the sun at the
instant of totalty and to photograph the
spectrum Of totality, and to photograph
the spectrum of corona; 8, to measure
the heat radiation of corona during the
eclipse and afterwards The photographs
Of the corona We're made by Prof. e. r.
Barnard and assistants. with photo
graphic telescope, siXty-two feet III
length. Photographs of the spectrum
were made with a variety of telescopes.
Photographs of the corona were made
with view TO showing the more delicate
structure of the corona, and also
10 show Its greatest possible eX-
tension. Photographs of the spec
trum will be useful in determining
the chemical and physical constitution of
the lower part of the suns atmosphere,
and perhaps in serving as criterion be-
tween the different theories of the solar
atmosphere between Prof. c. A. Young
and Sir Norman Lockyear, of England.
Observations at the Princeton station
were under the direction of Prof c. A.
Young with eleven assistants. Here the
instruments were used for observing the
spectrum of the corona. Forty-on pho
tographs were taken of the corona.
Visual observations of the contacts with
two telescopes and spectroscopic obser-
vation of contact, showed that the be-
ginning Of contact was fifteen minutes
ahead OF time. but that the duration of
totality was as predicted.
Observations of shadow bands were
made showing that a the heginni1., of
totality they were seven inches apart. and
decreased to two inches in forty-five
seconds Here their motion was from
southwest to northeast. 1t was curious
that at other stations in town the size
and position of fringes were the same,
but direction Of motion exactly opposite.
Corona seen with the naked eye was
fainter than those observed in the three
Prof. j. B. Colt of Boston, watching
the corona and protuberances, settled one
very important matter. that is, that there
were no white prominence in this parti-
cular eclipse
