reached that what Is known in the litera-
ture of yellow fever as the 'reactionary
fever the secondary infection (from
germs normal TO the body and the sec
ondary paroxysm,' is due to the passage Of
the injecting germ, the bacillus icteroldes,
I from It's primary colony In the lungs into
the general circulation, thus producing a
| secondary paroxysm' so familiar clinically
| in all marked cases, unless OF the slider
ante type.
This secondary paroxysm' Is then a
septicaemic one. and 1t depends not upon
bacillus coli communis or bacillus pro-
teus, or upon the micrococci but upon the
further colonization OF the specific organ
Ism in the blood, thus bearing out FACETS
observation that the decline of the fever.
the true secondary paroXysm,' Is as spe-
clfc as the rise or the primary attack.
The commission recognizes the coinci-
dent invasion of the blood by the organ
isms of the respiratory tract. among which
are found colon and proteus: 1t may be of
frequent occurrence, or these may invade
from the alimentary canal during the last
hours of life,' when the mucosa becomes
impaired from stasis and this invasion
becomes possible, such mixed septicaenr,ae
being of most severe type and frequently
! fatal. The commission, therefore, differs
entirely from Prof, Sanarelli in his theory
1 that the disease of yellow fever is prima-
rily septlcaemia. Indeed, 1t can scarcely
be matter OF surprise that Sanareli
formulated this opinion seeing that he al
ways produced, with tas he thought) un
important exceptions artificial infections
by internal NEGOTIATIONS, which, perforce,
must have produced septcaemiae.
The theory formulated and expressed
by DR.. Sternherg. u. S. A., that the germ
inal principle In yellow fever was to be
looked for in the alimentary tract, an
opinion evidently dependent upon the we'll
known influence of the disease upon the
organs adjacent and contributive to this
tract and portions of the tract itself. as the
duodenum. has been found untenable by
/ the commission since there Ia no record
of any one ever having isolated the spe-
citc germ from the canal save in the case
of its presence there through some capil.
larry hemorrhage into its lumen.
The influence of the various disinfect-
ing agents upon the bacillus icteroides
has been studied by the commission with
an eye TO the practical advantages to be
derived from better acquaintance with
the organism, and 1t is found that the
organism Is readily influenced by the me-
chanical and chemical agents In ordinary
use. Cold, however, is not factor in
this process, for the organism resists the
most extensive refrigeration, and no re-
/ liance can be placed on this mode of dis
Infection On the other hand, the organ
ism is very susceptible to dehydratlon
and can not withstand artificial drying for
more than ten to twelve days and Al Ia
very probable that It's susceptibility to

than to the degree OF cold experienced,

and no doubt is more so II the organism
has lost its vitality through evaporation
of It's fluids, as in n frosty atmosphere
The resemblance between the bacillus
ioteroides in its behavior on certain media
and the bacillus OF hog cholera has been
brought to the attention of the commits
sion, and 1t has deemed the observation
that there Is possible similarity In the
pathogenlcity OF the two organisms in the
domestic hog OF great Importance, al
though its experience in the observation
OF the cultural similaritias leads to the
conclusion that they are culturally dis
tinct, while the infection OF the domestic

roides to the.
