NATURE AND SCIENCE -.
A writer In Nature, discussing the
Prise Of the new chemical industry of
producing artificial perfumes, makes a
efgnif0Ant remark concerning the sense
|of smell in human beings. He declares
|that 1t Is, as yet wholly uncultured. In
walking through the country" he says,
I'VE can rarely identify a particular
|odor caught until the sight of the plant
Prom which it emanates makes us won
der at our hesitation" He suggests
that the growth Of the perfume indus
try, which results in the continual pro-
duction Of new odors, may lead to q
culuvation Of the neglected sense Of
smell, which may be capable of as ar
fisth development as that which color
perception has attained.
