previous contributions the Same subject His aten-
ton for the past year has been engaged study OF the
temperature OF the soil OF the moon. The important
practical bearing of this study is that it enables to
answer the question whether not atmosphere act'

showing the moon to be Intensely cold. Observations
made during the last lunar eclipse that even this
small amount OF heat instantly reduced the
passes into the shadow. The amount OF heat from the
moons soil Is much greater in winter than in summer,
probably becarse % the decreased OF moisture
in the atmosphere in winter since aqueous vapor
absorbs heat The paper gave rise to animated dis
