portion of the light into heat — ^an effect perfectly in harmony with the the-
ory of transverse vibrations as applied to explain the phenomena of polari-
zation of heat. On this theory, heat and light are different effects produced
by one and the same cause, and they differ physically only in the rapid-
ity and amplitude of their vibrations. The screen through which the
vibrations of light are propagated serves to diminish first the rapidity of
the vibrations requisite to prepuce the most refran^ble rays, and in pro-
portion as the transparency of the screen is diminiwed by any cause, in-
nerent or superficial, this arrest becomes more and more complete. As
the more rapid etherial vibrations have probably the least amplitude, we
infer from analogy in sound-waves, that as waves of least intensity have
the greatest amplitude, so with the luminiferous ether the extreme red
has but little brilliancy. Hence the loss of light from polished screens
is small compared with that observed in screens of opaline or rough'
ened glass, it would be instructive to examine the spectrum obtained
from a pencil of rays under each of the cases given, by means of a sul-
phid of carbon prism.

The subject of absorption of light bv screens has long since been care-
fully examined by Bouffuer,* By a photcMnetric method essentially like
Rumford's, Bouguer measured the loss of light in the beam of a candle
compared with a flambeaux and also with the light of full moon, in pass-
ing through 16 thicknesses of common window glass having an united
thickness of 21*43 millimetres z= *85 inch. The mean loss of light shown
by these trials was as 247 : 1, or over 99 per cent of the whole Quantity.

Six plates of the purest mirror plate-glass having an united tliickness
of 15*128 millimetres diminished uie light in the ratio of 10 to 3, occa-
sioned a loss of about 70 per cent of diffuse daylight A mass of very
pure glass about three inches thick diminished the light only about half
the latter amount, owing to its being a single mass and not cut up into
many planes.

He also measured the absorbing power of sea-water for light and
found as the results of experiments made in France and of observations
also in the torrid zone, that at the depth of 311 French feet the light of
the sun would be equal only to that of the full moon, and at th^^'
depth of 679 feet would wholly disappear. He estimates the tmns- '
parency of the air as 4575 times greater than that of sea-water, and

from the properties of a logarithmic cum (which he calk gradnlmcique)
whose fuDCtiont he had determined exp^mentally, he seiekB to fix the
outer limits of the atmosphere. Boogaer wa^an expert geometer and
sustains all his conclusions by mathematical demonstrations. His results
seem to have received less atten^n than they merits the onlj reference
to his researches I have seen being bj Dagoin in his excdlent TVosle dSr
Phynquey iii, 800, 1869. "*""

We should not omit in this connection to refer to the Tery interestnig
observations of Draper* on the spectrum formed by means of a platimmi
wire heated gradually from dull redness to perfect whiteness by a voHa-
electric current He observed the red part of the spectram to appev
first and as the heat and brilliancy of the wire increased the other ookm
of the spectrum appeared after the violet This result pofectly '
izes with views above expressed. — b. s., jr.]

AsTROHOMT. — I'/ew PlaneU. — ^A new planet, the 59th of the
between Mars and Jupiter, was discovered Sept 15, 1860, by Mr. James
Ferguson, of the Washington (D. C.) Observatory. It was then about
as bright as a star of the 1 lUi magnitude. — OauitPs Astran. Journal^
No. 140.

The 58th Asteroid (since named Concordia) was discovered March 24,
1860, by Dr. Luther of the Observatory at Bilk.

Personal. — Prof. J. D. Wuitnkt, State Geologist of California, sailed
from New York for his post of duty on the 22d of October last with
Prof. Wm. H. Brbwxr (late of Washington College, Pa.) in charge of
the Department of Agricultural Chemistry and Botany, and Mr. William
Asbburner who is assistant in the field Geological and Astronomical work.
The head-quarters of the survey will be for the present at San Francisco.
But the Act authorizing the survey contemplates the establishment of a
State museum, on the most extensive scale, the location of which is to be
determined by a future legislature, which place, wherever it may be, will
doubtless be also the permanent head quarters of the survey. For the
present, letters addressed to any member of the com, ** State Geol. Sur-
vey, San Francisco/' will reach their destination. Parcels or books for
Prof. Whitney or any member of the corps may be sent to care of B.
Westermann & Co., 440 Broadway, New York. No similar enterprise in
the United States has ever been set on foot on a more liberal and enlight-
ened basis, or opened under more favorable auspices as respects either the
importance of the work to be done or the ability of those charged with
the duty.

Tub General Index to the 3d decade of volumes of the 2d Series of
this Journal, now complete, occupies more than the space usually ap-
propriated to our Scientific Intelligence, and our numerous friends, whose
contributions are thereby excluded from the present issue, will pardon
the unavoidable delay.

Obituary. — Died in Montreal, Oct 9, Dr. W. P. Holmes, well known
as an early cultivator of mineralogy and botany in Canada, an active
promoter of the Montreal Natural History Society, and for the last ten
years professor of Medical Jurisprudence m McGill College, Montreal.
