This leaves the mid-brain without the check-rein of a reflective intellect, and the man will be senselessly hilarious or quarrelsome, jolly or dejected, pugnacious or tearful, and would be ordinarily described as "drunk." If in spite of this he keeps on drinking, the mid-brain soon becomes deadened and ceases to respond, and the cerebellum, the organ of equilibrium, also becomes paralyzed.
It is the surplus of molecular disturbance remaining in the cerebrum and cerebellum, and reflected back and forth among the cells and fibres of which these highest centres are composed, that affords the physical condition for the manifestation of consciousness. Memory, emotion, reason, and volition begin with this retention of a surplus of molecular motion in the highest centres.
Every Lemur which has yet been examined, in fact, has its cerebellum partially visible from above, and its posterior lobe, with the contained posterior cornu and hippocampus minor, more or less rudimentary.
For the two halves of the brain being once thus knit together, the progress of cerebral complexity is traceable through a complete series of steps from the lowest Rodent, or Insectivore, to Man; and that complexity consists, chiefly, in the disproportionate development of the cerebral hemispheres and of the cerebellum, but especially of the former, in respect to the other parts of the brain.
Martin in a whisper for explication was a necessity of Miss Bowyer's nature, or perhaps essential to the potency of her measures "now I will gently place the right hand on the fore brain and the left over the cerebellum, willing the vital force of the cerebrum to retreat backward to the cerebellum. This is the condition of the brain in the somnambulic state and in ordinary sleep.
This and other facts, including the manner of its connection with other parts of the nervous system, have led to the belief that the cerebellum is the chief organ for the reflex coördination of muscular movements, especially those having to do with the balancing of the body. In this connection it is subordinate to and under the control of the cerebrum.
A careless observer, forgetting that a soft structure like the brain loses its proper shape the moment it is taken out of the skull, may indeed mistake the uncovered condition of the cerebellum of an extracted and distorted brain for the natural relations of the parts; but his error must become patent even to himself if he try to replace the brain within the cranial chamber.
Cb. Cerebellum. M. Midbrain. P. Pons. B. Bulb. I-XII. Cranial nerves. *The Bulb*, or medulla oblongata, is, properly speaking, an enlargement of the spinal cord within the cranial cavity. It is somewhat triangular in shape, and lies immediately below the cerebellum. It contains important clusters of cell-bodies, as well as the nerve fibers that pass from the spinal cord to the brain.
Beneath the forepart is the cerebrum, and beneath the hinder part is the cerebellum; the latter was designed for love and the goods thereof, and the former for wisdom and the truths thereof; wherefore he that looks with the face to the Lord receives from him wisdom, and by wisdom love; but he that looks backward from the Lord receives love and not wisdom; and love without wisdom, is love from man and not from the Lord; and this love, since it conjoins itself with falses, does not acknowledge God, but acknowledges itself for God, and confirms this tacitly by the faculty of understanding and growing wise implanted in it from creation as from itself; wherefore this love is the origin of evil.
If the viscera, and other organs of life, had been found to be the same as in Protestant bodies; if the provisions of nerves, arteries, cerebrum, and cerebellum, had been the same as we are provided with, or as the Dissenters are now known to possess; then, indeed, they might have met Mr.
