uiring a fine degree of
Touch, the development is marvelous. The engraver passes his hand over
the plate, and is able to distinguish the slightest imperfection. And the
handler of cloth and fabrics is able to distinguish the finest
differences, simply by the sense of touch. Wool sorters also exercise a
wonderfully high degree of fineness of touch. And the blind are able to
make up for the loss of sight by their greatly increased sense of Touch,
cases being recorded where the blind have been able to distinguish
_color_ by the different "feel" of the material.

The sense of Taste is closely allied to that of Touch--in fact some
authorities have considered Taste as a very highly developed sense of
Touch in certain surfaces of the body, the tongue notably. It will be
remembered that the tongue has the finest sense of Touch, and it also has
the sense of Taste developed to perfection. In Taste and Touch the object
must be brought in direct contact with the organ of sense, which is not
the case in Smell, Hearing, or Sight. And, be it remembered, that the
latter senses have special nerves, while Taste is compelled to fall back
upon the ordinary nerves of Touch. It is true that Taste is confined to a
very small part of the surface of the body, while Touch is general. But
this only indicates a special development of the special area. The sense
of Taste also depends to a great extent upon the presence of fluids, and
only substances that are soluble make their presence known through the
organs and sense of Taste.

Physiologists report that the sense of Taste in some persons is so
acute that one part of strychnine in one million parts of water has
been distinguished. There are certain occupations, such as that of
wine-tasters, tea-tasters, etc., the followers of which manifest a
degree of fineness of Taste almost incredible.

The sense of Smell is closely connected with the sense of Taste, and
often acts in connection therewith, as the tiny particles of the
substance in the mouth arise to the organs of Smell, by means of the
opening or means of communication situated in the back part of the mouth.
Besides which the nose usually detects the odor of substances before they
enter the mouth. The sense of Smell operates by reason of the tiny
particles or the object being carried to the mucous membrane of the
interior of the nose, by means of the air. The membrane, being moist,
seizes and holds these particles for a moment, and the fine
