Lord Rose has been measuring the
heat that comes 70 Us from the moon
Using one of his great rejecting teleS-
copes IS burning mirror, he la, con leu
sed the moons rays upon one Of the most
delicate of heat-gaugers-a thetmo-piie
Without being able 10 determine u what
fraction of Tahrcnheit's degree the lunar
warmth increased the temperature of the
terrestrial atmosphere, he has found rs
an approximation, that the radiation from
the moon is about the ninety thou>anl th
part of that from theosun. He conceives
that the yariation of heat from one satel-
lite follows the same law as that Of It's
light / E.. that we have most warmth
from the full moon, and least from the
nearly new. By comparison with 4 ter
rcStrial source of heat, Lord Rose esti-
mates the actual temperature of moons
surface at lunar midday to be about 500
degrees Fahrenheit. This scorching re-
suits from the slow rotation of the moon,
which makes its day equal TO our mouth,
and from the absence of any atmosphere
to screen the lunar world Years ago,
Sir John Herschel, who has more than
once proved himself prophet by his ,a
gacious differences, remarked that 1.-The
surface of the full moon exposed to Us
must necessarily be very much heated,
possibly to a degree much exceeding that
