Vaccination.

1t may not be amiss at this time, threat.
ened as We are with visit from the dread
scourgc, smallpox, to look for moment,
at the means preventative.
DR. Flint In his treatise on the principles
and practice Of medicine, SAYS:
"Vaccinia and cowpox are names Of
disease Of the COW, which communicated to
man, DESTROYS, in great majority of cases,
for certain period, the susceptibility
to SMALLPOX, and. in the cases in
which It does not offer complete protection
against :::.e after disease, renders It as q
rule, mild and devoid of danger. Cow.pox
is transferred to man and from one person
to another by the introduction OF a virus,
and never, at distance, by infection. The
operation for its communication is called
lrci"afio". For the employment Of vac.
cinati''n as means Of preventing small.
pox, the world is indebted to the Immortal
JJenner The discovery was promulgated
by Jenner in 1898, after a series Of observ-
ations and experiments which had occu.
pied his attention t"r twenty years.
The practice of vaccination met at the
outset with much hostility, but Jenner lived
to see it triumph over all opposition, and
to witness the beginning Of benifcent ,e-
suits which will accumulate from age to
age until the end OF the world. =
Directing attention first to the descriptive
history OF vacCinnia in man, on the third
day after vaccination Nhe operation being
usually performed on the arm near the in.
s"rtinn Of the drltoil musclc(. red points
slightly elevated, that is, small papsules
are apparent at the spots where the vaccine
virus was inserted. On the fourth day the
papslles are more developed and Redeemed
On the fifth da. vcsicles are discovcrablc
The vesicles increase, presenting an UNI
h'icated appearance, and on the eighth dav
they attain to their fail development, being
elevated from two to three lines, and meas
nring one-third Of an inch in diameter.
The vericles, like those of small pox, are
mutilocular, tlattcned at the SUBMITS, and
cont lin transparent, viscid liquid called
the vaccine lymph. On the seventh or
eighth day red areola is apparant, extend
pocks, Increasing in redncss until the nint|,
or tenth day, and the contents Of the vrsi-
clcs become more or less purulent
The postules des>icate, and bv the fifteenth
day they are converted into black hard
scabs which fall of usually BY the twenty
fifth day from the date OF vaccination. In
view OF the immense importance OF IL true
and perfect vaccination to those who sup
pose themselves to be protected against
smallpox, the responsibility OF pertor,nin.
vaccination should never be undertaken bv
those not practically familiar with vaccini;,.
In 1860 case of spontaneous cow-,Nox
was discovered at Beaugencv, in France.
The virus obtained from this animal was
perpetuated through successive inocnla-
tons in heitcrs, conducted by Dr. Depaul,
under the sanction Of the French Acadamv
IT Medicine, and with the aid of the French
government The virus from this stock
having been imported into this country by
DR.. Henry a. Martin. of Boston, in 1870
he has since kept up the supply through a
continued series Of heier vaccinations: and
more recently the supply has also been kept
up from virus derived from this stock, bv
DR.. Frank p. Foster. under the auspices of
the New York Dispensary. The terms
animal and bovine virus are used to dstin-
gushed that derived Immediately from the
heifer; that derived from the human sub
iect being called humanized virus. The
import.nt practical question is, whether the
animal virus affords greater protection
against small pox than the humanized virus
That the latter has deterioated in conse-
ounce of removes from the COW seems
very certain. Vaccination with the long
hu,nanized virus is less constantly success
tul in producing vaccinia than formerly !:
the revaccination Of persons who have been
vaccinated with this virus is oftcner sue.
| >essful, and diminished protection is
shown by the greater number Of persons
who become affected with varioloid. The
opinion that vaccination with the animal
virus will secure more complete and a
longer exemption from the danger of con.
tracting smallpox. is shared bv manv, and
this virus is now extensively used in this
country, instead of the long humanized
virus. 81 After known exposure to
| small pox. if the person exposed have not
been recently vaccinated, or il there be any
reason to di>trust previous vaccination.
revaccination should. of course, bc prompt
" performed. 1t is proper to perform it
without reference to previous vaccinations,
with view to test the susceptibility and
render the security as complete as possible.
