TUBERCLE


the Beginning of Its Form nation.
What constitute and characterize
confirmed pulmonary consumption is
the presence of tubercles and bacilli
in the lungs.
In what consists tubercle? How is
it formed?
For long time, Psychologists expect
ed to find in the study of tubercle, of
it's composition, its beginning, and its
volutiOn, the enigmatical solution of
this most redOubtable disease, and
they have pursued with eagerness
these Investigations. Today, since
the discovery of the pathological ba-
ellis, this study which occupied SO
large a part in the works of Laenne,
d'Andral, of Cruveiller &c. . has
but a retrospective and secondary in
terest. Therefore we will confine our
selves to the statement of indispens-
able points.
1t is we'll known that tubercle al
ready formed, retrogrades no more
and invariably terminates in SOFTEN
ing without restoration, land is followed
by death, or by eicatrization or indur-
alton reparative (unhapDily too rare)
of the cavernOus LESSONS into the pull
monary tissues. In it's original con-
dition, this morbid growth called by
Laenne, military tubercle, and gray
granulation by Louis, is grayish
nOdule semi-transparent, hard to
the touch, making a very small pro-
lection upon the surface Of the tissue.
of which the size does not exceed
that of a hemp seed, but its form is
not always identical and presents
some variety. If under a magnifying
glass, the incipient tubercule. says
NJ. BochouX, you see Ii showing the
form of round production, not well
circumscribed, somewhat lost in
the middle of the healthy It's
sue around. Its color, which af
forwards becomes grayish, now is
that of gelatin, being rosy tint,
the deeper that the tubercle is small
er n. Elsewhere Luiys in his inves-
LEGATIONS concerning the formation of
tubercle, recognized the preeXlstence
to grayish granulation of some small
reddish bodies of the size of a millet
seed, flattening under the nail, de-
scribed by ROchOuX, d'AlmaZZOne and
Baron (2). This would be, he says,
some peripherial injections of the pull
monary lObules. From d'AlmazzOne,
(3), the tubercle described by Laeune
is but the second phase of the tubercle;
the first being constituted by small
red or red yellowish corpuscle,
being no larger than a millet-seed,
and adhering to the surrounding
tissues by vascular filaments. Doctor

liar observations; he saw some small
red specks, at first, apparently pro-
duced by sanguineous intiltratiOn,
but, afterwards invaded by the gela-
TIM form granulation, and he cOnclu-
ded that the tuberculous material is
but blood coming out from capillary
vessels and taking various transfer
nations afterwards. NJ. NJ. Heran
and Cornil, are of the same opinion,
tuberculOuS granulatiOns, they say,
are usually seen first, upon arterioles
of small size, and upon capillaries;
all these vessels are filled with blood,
and are distended; this points out,
that sanguineous fiuXiOn and an in
creased pressure of the blood are nee
essary for the formation of tub
circles. Oftentimes also, this man
ifest hyperemia which marks
their beginnings, is considerable
enough to give place to some sanguin-
eous ettusion, i; but afterwards, they
add, the entire absence of vessels is
ascertained; and in effect all authors
are unanimous in admitting that the
more the tubercles increase, the YES
sells which gave rise to this formation
become Obliterated, and these, the
tubecles, instead of going on to more
perfect organization, soon take on a
regressive transformation which be-
gins from the centre of the speck
formed by the older elements. This
centre becomes sometimes grayish
and pulpy, and sometimes yellowish
and Gaseous. Therefore there is what
is accurately demonstrated by patho-
logical anatomy in connection with
clinical observations.
In usual and common consump-
tions, the granular formation, or gran
ulo-tuberculOus is preceded by con-
gested condition of the lobular bron-
chias, and of the peribronchial capil-
laries, Of longer or shorter duration.
This is fact of capital Importance
in regard to therapeutics, and to
which till now, not received much at
tention and the Interpretation that it
deserves, have been given; because
this congested stage marks, we be-
lieve, a period during which the dis
ease can be arrested easily.
