The recent intensity of solar heat has, as
usual, given rise to considerable number of
fatal results, consequent upon direct exposure
to Its influence. y few words of information

SO sudden an exit from subsolar existence.


1t Is rather singular fact that sunstroke is
more fatal and more frequent in the temperate
than IN the tOrrld zone. New York has more
cases than Havana or Rio, in proportion to
population; even in Quebec the danger is quite

Is this momentary intensity which causes the
phenomenon of Sumstroke, and which seems to
be greater in regions without than within the
