crater. On the supposition that it is not of recent formation, 
it seems unaccountable how it could have entirely escaped the 
notice of such experienced observers as Schroeter, Lohrman, 
Beer and Msedler, Schmidt, Nasmyth, Birt, Neison, Klein, and 
others who have devoted so much of their time and attention 
to the critical examination and mapping of the moon’s 
surface; and I think, therefore, we are entitled, in the 
absence of positive evidence to the contrary, to conclude 
with Dr. Klein that it is a new appearance, though it may 
be doubted whether it is a true crater, as supposed by its 
discoverer, or merely a slight subsidence of a portion of the 
moon’s surface.

Moon with respect to the Sun,” by Joseph Baxendell, 
F.R.A.S. 
In a paper “On the Variations of the Daily Range of 
Atmospheric Temperature as recorded at the Kew Observa- 
tory by Professor Balfour Stewart, F.RS., printed in the 
Proceedings of the Royal Society, vol. xxv, p. 577, the author 
has shown that the daily range of temperature varies with 
the phases of the moon, and that the variations are greater 
in the winter than in the summer months, and opposite in 
character, the range in the winter being greatest at and 
shortly after new moon, and least at and a few days after 
the full. The novel and remarkable character of this 
result of the Kew observations at once suggested the desira- 
bility of discussing the observations made at other stations 
with reference to the phases of the moon, though it is evi- 
dent that as the daily range of temperature is dependent to 
a considerable extent on the greater or less prevalence of 
cloud, the direction of the wind, the hygrometric state of 
the air, &c., its variations could not in general be the same 
at all stations in the same phase of the moon, but that while 
at a maximum at certain stations during a given phase it
