MANS AILMENTS.
Due to His Departure from Quad
rupedal Position.
So Says a Scientist Who Has Made n
study of the Human Race-Some
of the Changes in Our
Anatomy. s. {.

An interesting paper was given atthe
three hundred and twenty-eighth cor
porate meeting of the Boston Scientific
society by DR.. Cora Hosmer Flagg, the
subject of which was the relation of
mans evolution to his ailments. at is
a common idea" said thespeaker, that
the human body is fixed and stable in
its structure and marvelously adapted
to its supposed uses for definite ends.
But all the evidences from compare
tive anatomy, cmbryology and physiol-
ory go to show that the majority of our
organs are combinations, rearrange-
ments and compromises necessitated by
the accidents of complexities
Much of this instability is due d.
rectly to the mechanics of the upright
position and to THE fact that the body
with its quadrupedal ancestry, has not
yet become perfectly adapted to its new
position. Every region of the body
shows evidences of this maladaptation.
Some structures are in a state of pro-
erosion; that is, they are tending to
more perfect adaptation. Others are
gone so far as to have gone wholly out
of use, remaining only as vestiges.
The pelvis and the backbone find
themselves with entirely d fferent du-
ties in man from their previous ones in
the QuGdrupeds. so that here are es-
recially marked differences. In the
beasts the pelvis has merely to bear
the weight of the end Of the back
bone. but in man il has all the weight
Of the trunk and the arms to sustain.
The result is that it has become COM
pletely bcwl-shaTcd and is not yet com
plctely adapted TO all its functions, so
that ii is the origin of numberless in
conveniences and diseases. In the same
way the backbone in man has assumed
two curves, one near the head and the
other near the base. AS another part
of the adaptation there is the loss of
some ribs and the shortening of the
spinal cord, the latter being the result
of the loss of the tail. These all mark
weak spots in the human economy, each
of which is known to be responsible for
a number of the common ailments of
man.
Many of the ailments quoted by DR..
Flagg were technical in their nature,
but still there were quite a number,
like the dwindling away Of the tibia,
that are patent to everybody. This
bone. the smaller of the two in the hui
man leg. is equal to its companion in an
finals and shares the work with it. But
in man in his upright position it is
merely accessory; it has lost strength
and size, and, being in an exposed po-
,ition. is subject to fracture. In the
same way the position Of the femur is
30 changed with reference to the body
that the weight it must bear not in
frequently results in fracture in its
weak place.
So far as the viscera is concerned.
they are nearly as well adapted to YER
teal as to horizontal position. Some
weaknesses have, however, been devel-
oped, among which may be noted the
vermifcrm appendix. which plays so
prominent part in modern diseases.
In like manner the speaker went on
to show how other difficulties are the
result of mans erect posture. The
heart, with a greater hydrostatic pres

added pressure is responsible for vari-
cose veins and similar troubles; the ex-
posing of certain important blood YES
sells, like the arteries of the leg and
arm, is a source of danger; canals
which have their Offices in the economy

use, sources of trouble. tonsilitis being
n malady of such a nature. In the brain
il is a noticeable fact that the diseases
are more commonly among those con-
volutions which man has added to the
previously existing brain of the ami
mails, and those lobes in which lie the
emotions or instincts common to nearly
all animal life are quite exempt from
disease. The more complex parts Of the
brain are affected; hence suicide. which
is the result Of thought, is common
among the insare, while they will re
