Our 0liu,
A Vaccine Farm.

| ~ u Q .fHII d
As many of our readers are doubtless
unaware of the manner in which pure
vaccine matter is obtained and prepared,
we publish below a sketch of "PennsyI-
vania Vaccine Farm" from the Franklin
Repository: .bs''.'- f'a" .s
On farm in Hamilton township, one
and one-half miles from Chambersburg,
DR.. b. Rush Senseny has stock of one
hundred heifers, from which he is pro-
ducing continually stock Of fresh vaccine
matter. The process by which this is
effected is interesting, aud we were well
repaid for driving with the doctor to the
farm last week to witness the operation
throughout. The heifers used in this
business are mostly well bred, and consist
of either full breed, hree,guayter or AaJf
Alderney stock. They must be in thriv-
ing condition, and from six months to one
year old. They are Stall fed, kept in clean
and well ventilated stables, plenty of clean
litter, fresh water and nutritious food. In
other words, the animal is kept up to a
normal, healthy aud thriving standard
First.-Heifers are secured by strap
ping them down to rack, on the back,
with each leg secured, strong strap
around the body, and the head tied down
Then they are shaved around the udder,
and vaccinated in from ten to thirty places
in order to produce vesicles of vaccinia.
On the eighth day after vaccinating they
are ready to yield up vaccine virus in its
different forms. ..asa. a.
On the eighth or ninth day the vesicles
are ready to tap in order to secure virus
This is done in four ways: L. Quills 9.
Ivory Points; 3. Lymph tubs, and lastly,
in about sixteen days, crusts. Quills are
as follows: The imported goose quill is
taken, boiled, filed, cut aud scraped, and
then dipped into the fiuidlymph, and thus
charged for use. I'd. The Ivory Point !:
Each point is dipped into the liquid virus
and charged as an Indian charges his
poisoned arrows.
Lymph tubes are long glass cylinders
which are filed with the fluid lymph, and
are then shut up by sealing each end with
wax. In using the quills or point upon
human beings, the quills are moistened,
and then when the abrasion has been
made on the arm, the quils or points, us
the case may be, are rubbed briskly upon
the abraded surface, and thus inoculation
of the true vaccinia is produced. This is
the true Jennerian system.
In order TO secure crusts of the true
vaccinia, the heifer is allowed to remain
untouched for about sixteen or eighteen
days, at which time the vesicles have
matured into hardened scabs or crusts of
virus, and may then be removed Each
crust is then carefully wrapped in gold or
silver foil, and is then ready for shipment
to any part of the world. This virus is
now being sent to every state in the
Union, to every territory, to Canada, Cuba,
South America, and to all the states Of
Mexico and Central America.
One great advantage in using animal
vaccine as a preventive of that dreaded
disease, small pox, is that there is no pos
sibility of inoculating the human system
with any constitutional disorder, q risk
which most persons fear to entail upon
themselves or their offspring when vaccina-
tion is demanded, and the only virus to be
had is from human crusts. Human crusts
may be good and pure, but we know that
often they are not, hence the safeguard is
animal vaccine, '' ~
