has been fiually determined that the
sun does not throw off q continuous
amount Of heat, frous year to year,
from month to month Hiud even from
day to day; that n'iJhcT does the
earth receive "A constant amount Of
solar heat; that these variations are
periodic and regular according 10

has set up apparatus for heat meas

The interesting question has oft
