From this we should naturally conclude that the ef-

tains quite different result According to him 1t is the

as matter of cOngatulaon and as special providence

that there is less atmosphere in the southern

1t s again assumed that the " northeast trade wind
belt" extends to the equator yet page S95 it stated
that southern limit in Summer is between the tenth
and twelfth parallels OF north latitude. and in Winter
second parallel north latitude. Thus the southeast
trades, according the Professors showing, have
plenty OF north of the equator without interfering
with the northeast winds.
