EXPLANATION OF THE ABOVE.
Ho,c 4 Nna Feels With His Hcad, Hands o.
Feet orr


To explain the above we must look to the
sensational, the perceptive and cebral con-
sciousness.
The term Sensation signifies the conscious
ness of an impression Properly speaking,
there can be be 10 sensation without con.
sciousness, crccpt in the case Of "reflex ac-
tion," when the impression produced upon
the spinal marrow, causing motion without
the consciousness Of the individual.
Our sensations are commonly referred to
the place where the impression is made (as
in Frazer and Hastings cases thus, we
speak of pain in the foot or in the hand,
though in reality the pain is felt in the
brain. This is proved by two facts If all
nervous communication between the part
and the brain be cut off, no impression
| however great can be felt and if the tI1,nk
of the nerve be irritated or pricked in any
part Of its course, the pain which is felt is
| referred always to the part where the nerve
is distributed. TO cite an example "a blow
on the Ulnar nerve (crazy -bone) causes a
| tingling sensation at the extremities of the
| fingers; and the pain after an amputation
of leg or an arm, is referred, not to the
stump but to the fingers or toes las in F. and
II. IS cases) that have been removed.
For the production of a Sensation, con.
| SCtOUS SldIe Ol iuLuu Is all tUilG Is required
while on the other hand, for the exercise of
the Perceptiye poWer, certain degree Of at-
tenti0n is requisite, or in other words the
mind must be directed to,cards the sensa-
ton as in +. and HIS.
The afferent nerves which connect the
different parts of the body with the brain
are called Sensory; whilst those which 60 tC
spinal marrow and which do not produce
sensations, are named by Sir Marshal Hall
ercitOr. Every atferent spinal nerve, then
is mad up with both sensory and exctol
fibres; and those parts of tho body endowed
with sensory fibres are said to be sensible
Sensations are termed Subjective when they
result from some internal cause ;-0Jjectir,
when produced by material object. Otter
e the subjective sensations completely imi
tate the objective ones thus, we may hav,
flashes Of light balls of fire and stars befor,
? the eyes, the ringing of bells and buzzing o
\ insects in the ears, and occasionally tn
n senses of smell and taste are excited by IN
!, ternal causes.
e Not only this of itself, is q distinct proo
v but the cases Of Messrs. Frazer and Hast
. ings, with the following illustrations, ar
I due solely to the changes communicated t
the sensorium, not to the change occurrin
. at the periphery of the nerve.
e Mr.. Frazer, had suffered from "corns"-
,ee the Index of pain" from previous suffe
re ing was registered in the cerebrum-thus h
10 mind was directed to them-in other wore
a reproduction of the past states of consciO,t
lg ness.
a. The sensation is perfectly real to the il
dividual who experiences it; but it orig

IN which produces its impression through ii
Of nerves Of Internal sensation, instead of o
m impression upon the nerves of the extern
be senses, to which it is referred.
II, With regard to all kinds of sensation
al. the change of which the mind is informe
: ] is not the change at the peripheral extren
re. ties of the nerves, but the change commuI
