The Eclipse.
The following notes of the solar eclipse of July

The following notes of the solar eclipse of July
30, as observed at two points in the Rocky Noun
tains, will be Of interest to the scientific reader:
RAwLINs, Wy. July 29th.-The weather here to-
day was fine. The sky was clear, and the obser-
vation a perfect success. Edison's experiments
with his tasIneter were quite satisfactory. DR..
Draper. Of New York. succeeded in obtaining
several photographs of the sun during the eclipse.
Professor Watson. of Ann Arbor, and Norman
Lockyer have just returned from Separation. where
the total eclipse lasted two minutes and fifty sec
onds. Professor Watson discovered an inter-
Mercurial planet of the size of a four-and-a-half
magnitude star, about D degrees southwest of the
sun. Mr. Lockyer says this eclipse was totally
different (the corona being ten times brighter this
time) from the one in 1871, showing a great yaria-
ton Of the brightness of the corona between the
maximum and minimum period of sunspots. He
obtained a faint photograph OF the continuous
spectatrum of the sun. and saw no trace OF lines or
rings through Mr.. Rutherford's grading. The
structure of the corona was well observed by him,
but no trace of an exterior ring was seen. and the
corona vanished instantly, while in 1871 it re-
manned visible for several minutes after totallty.
Only one faint protulerance was observed by Mr..
Lockyer. He is greatly surprised at the difference
of eclipses occurring in different sunspot periods,
and at the intimate relation of the brightness of
the corona to sunspots
DENVER. Col. July 9th.-Astronomical parties,
as far as heard from, allied to discover the planet
Vulcan, although able to discover stars of the sixth
magnitude.
Professor Young reported that he discovered no
ultra red or ultra videt lines, but that at the mo-
ment of totality all the Frauenhofer lines were
beautifully reversed. This was the most important
result of his observation. and confirms the obser-
yations made in Siam Both the FL lines were also
observed. Very bright lines were seen near large
b, which confirms Professor Pogson's observations.
He also saw the bright lines f and 1,474.
Edison's tesimeter failed to work satisfactorily,
and he used a thermpyle. which caused an I'M
steady motion in the faivanOmeter.
Professor Colbert r,ports that his observations
tend TO show that the moons path in the heavens
lay a little farther to be southwark than indicated
by the lunar tables.o else that the estimate of
the mt on's diameter 5 too large-perhaps both.
The measures mad by NJ. yesterday indicated
that the corona extended out on an average about
twenty-six minutes q an arc, corresponding to a
distance of fully 100000 miles, all around the sun.
1t was strongly striaed, and in the direction of the
ecliptic the rays ar, nearly straight. while above
and below the line they were markedly spiral in
their character. AMI some of the lines at the base
formed an angle d not less than thirty degrees
with a prolongatiol of the suns rays.
The chromosph.re was distinctly seen by Pro-
fessor Hough, indicating a thickness of some 1000
miles. The protuIerances were much less prOmi-
nent than at mos of the recent eclipses. Two
rather pale ones we're seen on the western side of
the moon.
