TUBERCULOSIS.
DR.. Koch's Theory as Presented and
Sustained by Him Before the
Medical Congress-

MeulCti OOuBTtBS.
Or. Koch did not lay down the positive
proposition that the two kinds of ttbcr-
culosis, human and bovine, are different
What he did was to enunciate n theory to
That effect. But he adducod strong argu-
ments to prove his theory.
DR.. Koch said in tho first place that as
long as he experimental with rabbits and
guinea pigs he could not discover n diff
erence in the tuberculous germs. But nm
on extending his Investigate tons to larger
animals, he at once discovered that bo-
vine and human baclli were in some de-
gree or in their whole nature far from
the same. Cattle were not susceptible to
the human tubercues. He next tried the ef-
feet Of the germs Of the two diseases on
small animals. When these were fed with
the sputum OF human patients thcv
throve. The bovine baciri caused early
infection and death. The experiments
were continued in the case of asses
sheep and goats with the same results
the scientist had now discovered that in
a general way animals could not catch"
human tuberculosis The medical con-
gross accepted this as satisfactory de-
monstration Lord Lister is said to have
regarded this theory so clearly proved
that 1t must remain a law of medical sci
ehce. But when Or. Koch urged his COM
tention for the incommunicality of bovine
germs to human beings he met Lord Lis
