Those who have not considered the SUB
iect mus be surprised at the quantity OF
blood which passes through the heart OF any
moderately sized animal in the course OF
twenty four hours. In man, the quantity
of blood existing in the body at any given
moment is probably from so to 40 pints.
OF these an ounce and halt, or about three
table spoonfuls, are sent ort at every stroke;
which multiplied into rs (the average rate
Of the pulse,) gives 1925 ounces, or seven
pints, in minute; j. e. 420 pints, or 25
gallons. in an hour, and 1860 gallons, j. e.
nearly "a hogsheads, in day. Now,if we re-
collect that the whale is said to send out
from the heart at each stroke Is gallons,
the imagination is overwhelmed with the
aggregate of the quantity that must pass
through the heart of that animal in twenty
four hours.


Itis a general law that the pulse of the
larger animals is slower than that OF the
| smaller; but even if we put the pulse OF
the whale so low as 90 in the minute the
quantity circulated through the heart cal
culated at fifteen gallons for each rnlsatlon
will be $4,000 gallons, equal to 5000 hogs
heads in q hours. The consideration oi
tins amazing quantity is, however, subject
OF mere empty wonder, if pot acconpalncd
with the reflection, that in order to produce
the aggregate amount, The heart is kept in
constant motion: and that in fact, it is in
ccssantly beating as it is termed, or throw
ing out the blood into the arteries, from the
first period of our existence to the moment
OF our death, without any sensation OF IA
tigue, or even without consciousness, except
ing under occasional corpcreal Or mental as
itatiou.
