es, 25,488 times more.
But as there was ephemeral fever on the twelfth day, it is right to make
a deduction, and to estimate the number of beats in that day as midway
between the twelfth and twenty-third days, or 18,432. Adopting this, the
mean daily excess of beats during the alcoholic days was 14,492, or an
increase of rather more than thirteen per cent.
The first day of alcohol gave an excess of one per cent., and the last
of twenty-three per cent.; and the mean of these two gives almost the
same percentage of excess as the mean of the six days.
Admitting that each beat of the heart was as strong during the alcoholic
as in the water period (and it was really more powerful), the heart on
the last two days of alcohol was doing one-fifth more work.
Adopting the lowest estimate which has been given of the daily work done
by the heart, viz., as equal to 122 tons lifted one foot, the heart,
during the alcoholic period, did daily work in excess equal to lifting
15.8 tons one foot, and in the last two days did extra work to the
amount of twenty-four tons lifted as far.
The period of rest for the heart was shortened, though, perhaps, not to
such an extent as would be inferred from the number of beats; for each
contraction was sooner over. The beat on the fifth and sixth days after
alcohol was left off, and apparently at the time when the last traces of
alcohol were eliminated, showed, in the sphygmographic tracing, signs of
unusual feebleness; and, perhaps, in consequence of this, when the
brandy quickened the heart again, the tracing showed a more rapid
contraction of the ventricles, but less power than in the alcoholic
period. The brandy acted, in fact, on a heart whose nutrition had not
been perfectly restored."
The flush often seen on the cheeks of those who are under the influence
of alcoholic liquors, and which is produced by a relaxed and distended
condition of the superficial blood vessels, is erroneously supposed by
many to merely extend to the parts exposed to view. On this subject, Dr.
Richardson says: "If the lungs could be seen, they, too, would be found
with their vessels injected; if the brain and spinal cord could be laid
open to view, they would be discovered in the same condition; if the
stomach, the liver, the spleen, the kidneys, or any other vascular
organs or parts could be laid open to the eye, the vascular engorgement
would be equally manifest. In the lower animals I have been able to
