HONGKONG, May 25.-The Daily Press
says: Some fifteen or twenty years ago
DR.. Patrick Manson, a young English
physician then practicing in Southern
China, instituted a series of researches
into the tropical diseases there present,
and amongst others into malaria, which
in the warmer regions of the world Is
one of the most prevalent. Much had
been done previously by others, more es-
pecially in Italy, where from ancient
times malaria may be said almost to
have made it's headquarters. Observation
had shown that the blood taken from ma
larious patients invariably contained a
large number of small black spots, to
which was given the name of Melanil,
and which were, moreover, shown 10 b.
associated with animal parasites of q
low order eventually classed as hema-
moebae, an order giving rise to a new
generation by spontaneous division. Now
the spores thus resulting circulated in the

emily performing any 1unction whaleyer
