Edaor Arcane is not yet satfaed in re-
gard 10 z31'e Undergraduates, relative to a certain
sscientide 6ubject which was inserted in your is
ne Of Nov. % But Mr.. Editor in the first
Ite, Imust - gratulate you upon The extern
I've circalali6 81 your paper, ard the superior
means of conveyance it must have over other
journals of the age.t A paper which is fircu-
lated throughout the United States and North
America might be said to be extensive, but
when it crosses the billomins waves of the great
oceaA and reaches Alssse, Germany in two
days, andsnotice be received thereof in The
same short period ofstime. Is it not remarka-
bic? What viii you call the age in which this
is done? truly progressive one" ] set aside
N aa',pnicality' and notice the piece in answer
4 The queries of Arcane, signed J. B. Boussin-
gauls, which appeared in your last issue, evil
IDENTIFY an extract from work of which he is
the author. He must have been writing upon
the principle, that any substance in passing
from denser to a rarer medium cold is produ-
eed and visa versa, when he speaks Of the cold
(which the air of lower regions experiences
in its upward ascent otherwise I cannot get
the idea. Butte ascribes it to an increased
evaporation ana not to the principle that pas
sing from densefto a rarer medium cold, is
produced. If thes gentleman who forwarded
this extract to the Free Press endorses the theOo
ries assumed BY Bousingauli we wish him to
define his position; then we Will discuss the sub
ject with hin-for as it is 1T most certainly needs
an explanations We cannot tell whether he
means the evaporation of the air, or evapora-
ton from the surface of the mountains, though
for the sake of argument we will suppose that
he means the formation of vapor from the SER
face of those hi ii points increased under d.
unfinished pressure. But there vtIrrr cruises
which influence evaporation, among which is
the temperature of the atmosphere, which acts
very materially upon the operation for we all
know that it goes on more rapidly under tenn
perate pressure of2120 than under one of tenn
perature Of 500. Now we would suppose from
this fact that intense cold retarIs, while dimn-
ished pressures Facilitates the process of evapo-
fation.- Htsce I affirm that evaporation from
those high points, is retarded by the intense
cold, in proportion not far below the degree of
which it is influenced by the diminished pres
sure. As to his nocturnal radiation do not
consider it as touching the subject at all, for no
object can give out more heat duri9g the night
than which it receives during the dav in uni
t6rm temperature of TIE weather. But it seems
TO rs that the radiation Of heat would keep up
the temperature of the surrounding atmosphere
Father than diminish it, which goes on until a
uniformity is restored, where there, ceases to be
any radiation at ALL / do nOt mean. to compete
tbeearned BOussingault, but leave it for the pubo
lie TO saXFhether the extract explains the cause
of such heavy falIsof SNOW in those mountains,
while at the Seme time it rains profilsely here
in he valley. hoping to hear from the individu-
