der, beginning with the last % @ 7
The blood Of human being is essentially different
from that of any other animal and the blood of one
animal differs from that of another. The blood Of
sheep transferred into cat kills the cat The blood
of any ANIMAL except one Of s own species, forced
into the veins of = man, brings ON paralysis and
death. Science has analysed wherein the blood of
one animal varies from that of another, and has
shown that what experiment has revealed can also
be demonstrated physiologically.
Even in the same animal there are two kinds OF
blood one called arte-al which rushes FRONT the heart
and the other venous which pours into the heart.
The first bright scarlet the last purple. The first
passes into smaller and smaller vessels till i reach

larger channels, till it emptes itself in huge
stream into the heart The arterial blood is pure
the full of wasted tissues. The Office OF the
lungs is to cleanse the blood which is then
thrown back into the heart and afterwards propel-
led through the body. Thus, it will be seen, a con-
tinua waste and repair goes on in the human body,
Of which waste and repair the blood is the instru-
ment. 1t has been estimated that, in the course Of
year, the arteries carry to the various tissues not
less than three thousand pounds weight of nutrtve
NATTER while the veins bring back to the heart and
lungs, to be expired from the latter, many thou
sand pounds Of wasted tissues. Both arterial and
venous blood contain oxygen and carbonc gas, the
popular notion to the contrary Notwithstanding; but
arteria blood contains much the larger proportion of
oxygen. In their constituents the gases excep-
ted there is but little difference between arteral
and venous blood.
In man of average weight the quantity Of blood
is about ten pounds. How much of this can be ex-
t-acted without causing loss Of life it is difficult al
WAYS to tell In the medical books there is state
ment of hysercal woman, who was bied one thou
sand and twenty times in nineteen years young
man, according to Haller, bled pounds and
half daily for ten days. and yet survived-a story
almost incredible. The chief constituent Of blood is
water. which forms nearly one eighth Of the whole.
Albumen enters into its composition in the proper
ton of seventy parts TO a thousand. Sugar. salts,
and cellular matter compose the remainder the last
in the proportion of hundred and thirty parts to
a thousand.
These cells or discs, as others call them, the
most curious part Of the blood 1t would be idle to
enter into explanation of their composition, and
sieatifc men themselves not agreed upon the
subject Nor is it possible in the present stage of
human knowledge, to tell how blood sustains life,
except as an instrument and vehicle to carry
the repair and remove the waste. which are indis-
pensable to Philadelphia Ledger.
