ongue. The distance at which the two points could be distinguished
from one point, on the tip of the tongue, was called "one line." Using
this "line" as a standard, it was found that the palmar surface of the
third finger registered 2 lines; the surface of the lips 4 lines, and the
skin of the back, and on the middle of the arm or thigh, as high as 60
lines The degree of sensitiveness to Touch varies greatly with different
individuals, some having a very fine sense of touch in their fingers,
while others manifested a very much lower degree.

In the same way, there is a great difference in the response of the
fingers to weight--a great difference in the ability to distinguish the
difference of the weight of objects. It has been found that some people
can distinguish differences in weight down to very small fractions of an
ounce. Fine distinctions in the differences in temperature have also been
noticed.

The sense of touch, and its development has meant much for Man. It is the
one sense in which Man surpasses the animals in the matter of degree and
acuteness. The animal may have a keener smell, taste, hearing and sight,
but its sense of Touch is far beneath that of Man. Anaxagoras is quoted
as saying that "if the animals had hands and fingers, they would be like
men."

In developing the sense of Touch, the student must remember that
Attention is the key to success. The greater the amount of Attention the
greater the degree of development possible in the case of any sense.
When the Attention is concentrated upon any particular sense, the latter
becomes quickened and more acute, and repeated exercise, under the
stimulus of Attention, will work wonders in the case of any
particular sense. And on the other hand, the sense of touch may be
almost, or completely inhibited, by firmly fixing the Attention upon
something else. As an extreme proof of this latter fact, the student
is asked to remember the fact that men have been known to suffer
excruciating torture, apparently without feeling, owing to the mind being
intently riveted upon some idea or thought. As Wyld has said, "The martyr
borne above sensuous impressions, is not only able to endure tortures,
but is able to endure and quench them. The pinching and cutting of the
flesh only added energy to the death song of the American Indian, and
even the slave under the lash is sustained by the indignant sense of his
wrongs."
