a few months these bovine bacill had
changed into the human type. Put back
again into the serum n cows blood they
changed back into their original type.
Hundreds OF these experiments were
made. various animals besides cows and
men were called on for serum. The orig
inal bacilll at times were from human
sources. But in every case the transfor-
nation came. In human serum the bacilli
became OF tie human type. while in bo-
vine serum the baciIi. even IL originally
human in type. became bovine. Not

1t is during childhood that milk forms

has prepared tables in which are set forth
the facts that have been observed in the
long continued experiments and observa-
tions OF half score OF the greatest in
vestigators OF Europe These figures show
that the percentage OF infection i'm chill

per cent. observed by Won Pirquet in in

does not mean that all of these children had

This. in as brief and untechnical form

der's discoveries. upon which are based
his new theories in regard TO tuberculosis
In recently published pamphlets pr
Schroeders theories are supported by
Calmette tho most eminent living French
investigator. and by Northmann. who. In

In the United States Dr. Schroeder +

bald Smith Of Harvard University and

research Laboratories, New York citE
health department
DIR. Smith has followed br. Schroeder
experiments in regard 10 the possibility
or impossihility Of infection with tuber-
cuiosis by inhaling dust containing dried
human sputum and has stated that Or,
Schroeder is correct in his contention that
infection cannot occur by this means.
DE- Park strongly supports DIR. Schroe-
der In maintaining that the age Of ori.i-
nal infection with tuberculosis Is always
an early one-below fifteen to seventeen
years. lie also supports Or. Schroeder
in the contention that the hacilli of bo-
vine tuberculosis infect children, and that
as these bacili remain in the human sys-
tenn they are transformed into the human
type Of tuberCle bacilli. In 30 cases re-
ported by Or. Park OF children over six
teen years of age not single case show
ed the presence OF the bovine form or
type Of baciili. In fifty-three cases re-
ported by him Of children from five 10
fifteen years of age he found nine cases
of infection with the bovine baclli while
in eighty-fou cases which he reports OF
children under five years OF age the bo-
Vine type of baeilli were present in TWEEN
ty-two cases; twenty-five ont OF the
had bovine tuberculosis Dr
Park further reports that in nne cases
OF tuberculosis in children under six
years OF age treated in the New York
Hospital. these children be-
ing fed exclusively unmodifed COWS
milk, 81 per cent were found to be in
fected with bovine tuberculosis.
These new discoveries BY DR.. Schroeder
mean simply that the old accepted be

we cannot. The wind-bloan dust OF the
streets does not contain any living tu-
bercle bacilli. and even II il did We could
not breathe IL into our lungs, because of
physical and mechanical safeguards
within the structure OF the lungs them
selves.
The new discoveries mean that the hu-
man individual contracts tubercu losis al
most before that individual lis out OF
