According to Professor S. r. Lang
lev, the well-known American astron-
omer. the temperature a the sunlit
surface of the moon has been commonly
over-estimated. and probably does not

Richard A. Proctor. in his elaborate
work on the moon. says that. during
the lunar day. the surface Of the moon
burns. one may almost declare, with a
heat of some five hundred degrees
Fahrenheit. if the differences of our
most skillful physicists and the evidence
obtained from our most powerful means
Of experiments can be trusted.
