occupations, IN orOSr To Nnu out
whether the germs were more preva.
lent among individuals engaged in in,
door occupations than those working
out OF doors.
Second--the examinations were
made ON the same individual at diff
tercut times Of the year In order TO
determine the eject OF the season OF
the year ON the prevalence OF the
germ,
Third-these examinations were sub.
ieeted to further tests to ascertain the
degree OF virulenco of the pneumonia
germ Mt different times OF the year. or
the 80 individuals whose saliva was ex.
amined at different times all were in
ordinary normal health at the time the
saliva was collected, and none ot them
SO far as II was known. were sick for
some time after the collections were
made, SO that they may fairly be said
to have hoen healthy persons,
Germs In over one.third.
or the so individuals examined the
saliva OF is showed the presence OF
this germ; |. O., SO per cent. OF persons
apparently In normal health have In
their mouths these deadly organisms
without having them affect their gen.
eral state OF health II this percent
age holds true for all persons II is
seen that over ono,third of persons In
good health need only to have their
vitality lowered In order to develop
eases of pneumonia, The percentage
obtained from these Investigations is
considerably higher than those secured
by the previous observers who have
made u study Of this subject, The in.
dividuals chosen were representative
ms far as age, social class. and oocu-
patton were concerned. for OF tho
90, u were university students, two
high school students, six ward school
pupils, FIVE toamsters, five carpenters
working out of doors, Ave craftsmen.
aud one housewife.
Prevalence Varies With Occupation.
In order to study the influence OF
occupation on the distribution OF this
germ, three classes of persons were In,
yestigatCd; those working within
doors, those engaged partly indoors
and partly out Of doors, and those en-
ployod entirely In out of door work,
Five craftsmen, working In n machine
shop were selected ms the group whose
work kept them within doors constant.
ly, Five university students and
five teamstcrs and hack drivers con
stltutod the group of these engaged
both in and out of doors. while the
five carpenters were selected to repre-.
sent those who work out of doors nj
all seasons OF the year The results
obtained from these examinations were
very striking Among the Ave car.
penters who were out of doors con.
stantly, no pneumonia germs whatever
were found in tho case OF the five
transfers, who were partially indoors
and partially outdoors, the organisms
were present In two, or forty per
cent, OF the group of FIVE university
students, the germs was discovered
IN two at one time. Bpd three ut an.
other giving percentage OF from 40
TO GO per cent The five craftsmen
whose work kept them within doors
constantly, were all found to have the
micro-organism present in their salivo,
Thus although the results may not ho
absolutely conclusive, the conclusion
apparently may be drawn that those
engaged entirely in indoor occupations
may be pro.disposed TO attacks of the
disease Occupations. therefore, may
be considered factor of considerable
Importance, AMI evidently accounts for
the variation In the distribution OF this
germ In the saliva Of healthy individ-
uals
