theory that one class Of microbe is often
antagOnistic to another, and that those
which are normally harmless may, I'M
der certain conditions. become exceed
ingly noNious.
The recent discoveries of the inf1u-
ence eNerted by glycerine on many
micro-organisms are full of interest.
1t is found to be chiefly the noxious
germs which are killed out by glycerine
in the course Of few weeks; it may be
that this accounts for the remarkable
healing power of glycerine in abrasions
of the skin. The microbes soferysipclas.
typhoid, and diphtheria die out in
about three weeks. while the hay baci.-
lus shows 4 greater power of ofresistance.
Careful experiments by Dir. s. Mockton
Copeland and f. r. Blaxell conclusive
ly prove that the tubercle bacillus in 4
42 per cent. mixture of glyccrinc is
killed in period of four weeks.
Vaccine lymph has for many years
past been preserved Ivy an admixture
of givccrinr: it i~ now found that
GlNcerlnr i Il >.t;i-la.cr whi ii may. as

lymph, so that the whole mixture be-

Mockton Copeland laid it down not
only that the careful preparation with
glvcerine OF vaccine derived from the
calf leaves the resulting vaccine ma
lerial as active as the vmph itself had
been before the almiNturr. but that the
glvcerine exercises. in the course OF
some weeks of careful storage Of the
material, a ccrmicidal influence on the
extraneous microbes commonly met
with in vaccine lymph. Even when
tuberclc and the other dcletcrious
bacilli were. for experimental pur-
poses. Intentionally mixed with the
combined glycerine and vaccine, the
microbes were iounh, in a
month or less, to have been entirely
destroyed. The result of this expert
ment seems to be in harmony with the
theory of the antagonistic qualities of
various microbes. The lymph has also
been eNperimentally mixed both with
vaseline and with lanolinc. bat the
same results do not follow: the mixture
NAV he rendered tree from cXtrancous
bacteria. but it i found to he inefca-
cious as vaccine. G. Gycerinated calf
lymph appears, therefore, to be the
surest and the safest that can be used
for vaccination, and by its use we may
hope to eliminate the incidental dam
gers which have justly prcjudiced peo-
pie against compulsory vaccination.
In Germany the systems OF vacci-
mating from arm to arm and direct
from the calf have been abandoned,
and the use of G gycerinated calf-lymph
is general throughout the empire. BY
the addition Of glycerine the amount
of vaccine procurable from one calf is
enormously increased. Formerly one
calf was made to serve for some two or
three hundred vaccinations, but now
the glycerinated vaccine from on" ami
NAL can be made to suffice for li.y,.,u
thousand operations. Where vaccine
from one calf is used on so enormous
scale, the imperative necessity of eX-
treme precautions is apparent. The
most complete establishment for the
preparation of vaccine is at Cologne,
under the direction of DR.. Nanselow
Five grammes of vaccine are there
mixed with twenty-five grammes of
water and fifty of olvcerine, and this
compound sutlices for five thousand
children. The building has been
specially constructed for the purpose;
the walls of the rooms are of glass tiles
and Partisan cem"nt. The shelves and
tables are Of glass. The director and
his assistants wear over their clothes
linen c,verS. which are Stcriliznd prior
to every occasion on when they are
used.
In Paris public vaccination is often
performed in the open streets. After
due notice is given, the medical staff
arrive, bringing their calf in 4 van,
and the French mothers gather round
with their babies. who are operated on
under the gaze of an admiring and in
terested throng,-a practice obviously
open to serious dangers.
1t has been known for years that the
blood of eels contains Il highly poison
GUS principle; a dog inoculated with 4
dozen drops of cells blood dies in ten
minutes. This discovery was made
about ten years ago by two Italian
brothers, named Mosso. The poison
is readily destroyed by heat, and by
mere lapse OF time, wherein it differs
from IA snake poison. which long re-
