What "TriChiniasiS" is.
HOW WORMS GET INTO HUMAN MUSCLE

HOW WORMS GET INTO HUMAN MUSCLES.
DR.. Wyntcrs recent work contains pa
per about tn. unpleasant Trichiniasis cais-
cd by the II mute worm Trichn;@ Spiralis,
which professor Owen found as long ago as
1865, in musc.es taken to him from the dis
secting rooEs Of Guys and st, Bartholo-
news Hospitals in London.
How the Sorm got into the muscle was
Unknown tip Zenher, in 1860, conhected
Cause withiegect by tracing the trichinp in
the votnhtafYmnscles ofa girl who died, to
Ethe trichiG{e;in raw ham and Sausages that
! Sic had eaten. Pork is the dangerous
mont the pig gets trichire by eating cad
rats and other gaubage, aud If the pigs
flesh be.notso thoroughly cooked as,tc lin
the WORMS il may carry living trichiuee into
the human stomach, @kfnce they pierce
their way to tho l.lAsaN assas. D. Wynter
says:
After entering the alimen,ary canal the
parasite finds its breeding ground, and
brings forth immense numbers of. young,
which immediately begin to make their way
through the coats of the inlestines and
migrate into their muscles. .'''.'
IL is a singular fact that these disapreea
bic ndventurers always select the volu ntary
muscles,' or those which are moved at our
will. The heart and kindoys, and those
parts of the viscera which att independent
y of the Will, are scarcely ever effected 1t
is, indeed, q matter of dispute how the
worms get distributed so generally over the
body, some anatomiss asserting that they
make their way directly by boring as tho
ship worm bores through piece Of timber,
but Dr.. Thudichum, who was appointed i'm
1864 10 investigate the subject by the niedi-
cal officer of the Privy Council, asserts that
they enter the circulation, and are in this
manner distributed equally OYER every part
of the body. To use hiswords "Arrivcd
i'll the capillaries Ocrmnal blood vessels, J
they penetrate their two coated walls, sepa-
rating the fbres as man separates tho
branches Of n hedge when creeping through
il, and are now either at once in muscular
TISSUES, their proper feeding ground, or get
into inhospita6lG tissues and cavities, and
there either perish or escape from them by
renewed effort at locomotion, enter the
circulation II second ,imo. and unimely
perish in the lungs, or arrive in sOIno laus-
Gle TO obtain n la;e asylum" -.
THIS hypothesis certainly seems the most
reasonable, as it is in agreement with the
knows m cans By which other entoaa migrate.
Arrived'at the muscular tissues, i; seems
again questionable whether the worm at g,
:aCkS the muscles. Leuckhart saws they
penetrate the sarc6lemmn, and eat the mus
cular fibre itself DR.. Thudiehum SAYS that
he has never seen but once the worm in the
muscle, but always outside of it,, Ii is Ger.
tainly n strangefact, that, in many cases,
persons attacked with triehiniasis, have not
only perfectly recovered from its effects
but have become as strong as ever, 1t could
scarcely have happened that the muscles of
these patients has been fed upon by vast
colonies Of worms, which would have inevi.
tebly destroyed them beyond repair. The
probability is that the worm finds its way
into all the tissues. Between the third and
fourth week after immigration, the trichine
has become full grown, and now it begins TO
prepare its capsule. ltbecones fixed to the
spot in which 10 is, solid matter is deposited
around il. and curled up, it lies immovab
ip it's plastic capsule, and dies unless re-
ceiyed again into the alimentary canal of
another animal, which in this case of course
II never does! '''a - 9db =, i.i's

that many persons suffer little harm from
