The wonderful faculty OF the human
bod for developing nervous power, and
the extent 10 which bodily activities de-
priye the nervous system of that power,
are illustrated by the following calcnla-
ton: a seamstress complaining OF feel
ing tree after The days work. led the
writer to makean estimate OF the bodily
power expended during the day.
Following are tho data n ealcula-
ton. llrst-The arm Is played radially
nj the shoulder and, together with the
hand, is lifted a varying distance In
taking every stitch, the distance lifted
being reduced as the thread becomes
shorter. Second-The weight OF the
person ; relaxed arm was found 10 be
pounds. az separated from the
shoulder II would really weigh more
Third-Ihc next day the number OF
stitches taken in one hour oil average
work was counted and found TO be about
J.. on, amounting in ten hours to l2,Ohu
stitches ourth- The average length
OF thread was estimated at II inches.
Now the arm, II dead matter, would
have required an amount OF power sui
heient to lift its lead weight, . ponds,
every time a stitch was taken. For II
is a mechanical law that 10 nov n GER
tain weight OF living matter req Tres the
same amount OF lfe-toree that an equal
weight OF dead matter requires OF any
torAe.
b hgures would he thus: 10000
times . pounds equals 63,Olp pounds,
the total weight lifted. That IS, the
amount OF power expended IN arm eN
ereise during the day s sewing work, II
concentrated IN a single MT, would raise
63,Ooo pounds t5l tons a distance OF
II inches IN . seconds, equivalent TO so
morse power. furthermore, AS the per-
son walked apout ',UOO leet, the DIS
lance from home TO the wori-room,
four times during the day, the compu-
tation OF power expended IN walking
