That a whale is a mammal, not
a fish has been known since the time
of Aristotle; however, the great systematist
Whitman classed them as such.
Although few people realize that all the
air held in the water, it yet
breathers air by means of lungs &
must carry to the surface to a
dischage the air from its lungs
& take a fresh inspiration; &
any land mammal would
do just the same. The
when an whale comes to the surface often
its first act is to discharge the
air from its lungs & take a
fresh inspiration as a land
mammal would do under
like circumstances. This air is
saturated with water vapour at
a high temperature, & when it
strikes the cold upper air, sudden-
ly condenses forming a column
of steam or spray which is called
the spout. Thust it is that the
mammal gives that the
animal rarely blows water
from out its nostrils.
