ness of destroying valuable property

THE details of the experiments are
most interesting. but ii must here suf-
fce TO briefly sum up the principal
conclusions of this admirable board of
Investigators of which Reed was the
master mind:
81. The specific agent In the causa-
tion OF yellow fever exists in the blood
of a patient fc- the arst three days OF
his attack. after which time he ceases
to be menace to the health OF jhers.

period is powerless to convey the dis
ease to another person by its bite Sp.il
about twelve days have elaE1ed. but
can do SO thereafter for an Indefinite
period, probably during the remainder
OF its life
%. The disease cannot in nature b.
spread in any other way than by the
bite OF the previously infected steg-
omyIa. Articles used and soIled by pa
tIents do not carry infection.
These conclusions pointed so clear
