analogous to our sense of smell, which in the animal world directs the
new-born infant to its source of nourishment, and they may thus possess a
faculty of perceiving as well as of producing odours.

Thus, besides a kind of taste at the extremities of their roots, similar to
that of the extremities of our lacteal vessels, for the purpose of
selecting their proper food: and besides different kinds of irritability
residing in the various glands, which separate honey, wax, resin, and other
juices from their blood; vegetable life seems to possess an organ of sense
to distinguish the variations of heat, another to distinguish the varying
degrees of moisture, another of light, another of touch, and probably
another analogous to our sense of smell. To these must be added the
indubitable evidence of their passion of love, and I think we may truly
conclude, that they are furnished with a common sensorium belonging to each
bud and that they must occasionally repeat those perceptions either in
their dreams or waking hours, and consequently possess ideas of so many of
the properties of the external world, and of their own existence.
