La tho spring thoy arc lighter than in

Manson took with him to London

ho caused to bito his son, who had noyor

nevertheless developed typical attack
of intermittent fover.
Malaria, therefore, is a malady whose
contagious character manifosts itself
uniquely in places whero there are ano
phclc mosquitoes and during tho warm
season. Vegetation, temperature,
stagnant wators and marshy ground
combine powerfully to spread the evil,
because thoy make conditions favorable
for tho propagation of both mosquito
and germ. But thore arc localities
like Poestum-w which have become onlv
recently infected; aud it is clear that
malaria may be other brought into q
noighborhood or stamped out of it.
