The idea behind this supposition has been that, as the day draws to an end, the circulatory mechanism becomes fatigued, the vasomotor center exhausted, the tone of the blood vessels deficient, and the energy of the heart diminished, and the circulation to the cerebral arteries lessened. The ordinary pressure of the blood in the arteries of young and healthy men averages 110-120 mm. of mercury.
He mentions the various signs which "contributed to indicate the existence of an emotion as lively as the animal had ever shown us before the spinal operation had been made."* He infers that the physiological condition of the viscera cannot be the cause of the emotion displayed under such circumstances, and concludes: "We are forced back toward the likelihood that the visceral expression of emotion is SECONDARY to the cerebral action occurring with the psychical state.... We may with James accept visceral and organic sensations and the memories and associations of them as contributory to primitive emotion, but we must regard them as re-enforcing rather than as initiating the psychosis."*
From their small start he became rapidly wealthy as a dealer in real estate. Mr. Stoneleigh was a generous eater; his foods were truly simple in variety but luxurious in their quality and richness. Prime roast-beef, fried potatoes, waffles and griddle-cakes supplied him with heat, energy and avoirdupois. He suddenly quit eating at fifty-eight there was a cerebral hemorrhage one night.
Simple-minded, ignorant of cerebral disorders, loyal, and laborious, Ambroise could not speak of these disquieting things indeed, he only worked the more.... At last, one night in late summer, she did not appear.
And conversely the prolonging of the plastic period of infancy, entailing a vast increase in teachableness and versatility, has contributed to the further enlargement of the cerebral surface. The mutual reaction of these two groups of facts must have gone on for an enormous length of time since man began thus diverging from his simian brethren.
The cerebral processes by which the acquisition of knowledge is made are the same for each sex; but the mode of life which gives the finest nurture to the brain, and so enables those processes to yield their best result, is not the same for each sex. The best educational training for a boy is not the best for a girl, nor that for a girl best for a boy.
The excitability which had been showing itself in spasms and strange paroxysms had been transferred to those nervous centres, whatever they may be, cerebral or ganglionic, which are concerned in the emotional movements of the religious nature. It was taking her at an unfair disadvantage, no doubt.
The communication is usually between the common carotid artery and the internal jugular vein. The resulting interference with the cerebral circulation causes headache, giddiness, and other brain symptoms, and a persistent loud murmur is usually a source of annoyance to the patient and may be sufficient indication for operative treatment.
He prescribed a hot bath and a "closer supervision of the evening meal." The dilatation of the cutaneous capillaries consequent to the bath lowered the cerebral circulation and to some extent reduced the intensity of the illusion. The cue to the cure appeared when the child, in expressing his fear, complained because he could not see the parent who sat beside him on the bed.
The more I reflected the more convinced I grew that I was dealing with a case of cerebral disease; and though I dismissed my servants to bed, I loaded an old revolver, that I might be found in some posture of self-defence. Twelve o'clock had scarce rung out over London, ere the knocker sounded very gently on the door.
