59. THE EAR.
1. If you look into the ear of th e boy sitting next
you , you will see a little tunnel leading right into the
head. Thi s tunnel leads to the most imp ortant parts
of the ear, which are lodged within a mass of hard
bone for protection . What we commonly call th e
ear is only th e external ear. It is a trumpet for
collectin g th e quick tremors of th e air, which we call
" sound-waves," and for directing them into the tunnel
we have just mentioned.
2. This external ear is not necessary to hearing,
and those who have had their ears cut ofl:--a punishm
ent sometimes inflicted by the Red Indians
upon th eir enemies- can hear fairly well, th ough not
qui te so plainly as before. To many animals the
outer ear is of greater service than it is to man :
the horse, by turning its ears about, finds out in
what direction a sound is loudest, and thus knows
whence it proceeds. Notice how a horse will turn
its ears towards you, if you make a noise to attract
its attention.
