This reaction is in general in the direction of increased amplitude of respiration, but diminution of the pulse, depending on a peripheral vaso-constriction.
And if this be so, the implication is that the interior body of the Sun, higher in temperature than its peripheral layers, may consist wholly of the metals of low atomic weights, and that this may be a part cause of his low specific gravity; and a further implication is that when, in course of time, the internal temperature falls, the heavy-moleculed elements, as they severally become capable of existing in it, may arise: the formation of each having an evolution of heat as its concomitant.
They are pretty certainly the starting-point in those picturesque dreams in which figure a number of bright objects, such as beautiful birds, butterflies, flowers, or angels. That the visual images of our sleep do often involve the peripheral regions of the organ of sight, seems to be proved by the singular fact that they sometimes persist after waking.
The same importance which belongs to the removal of bodily pain in the treatment of a peripheral disease may be given to its mental counterpart, to the worry, excitement, and emotional shock. They all stand in the way of a real success in any cure.
The image results from a partial cerebral excitement, which sensation results from an excitement which also acts upon the peripheral sensory nerves, and corresponds to an external object an excitant which the image does not possess.
Prudden reports the case of a girl of twenty-five who, during convalescence from variola, became paraplegic, and during this time multiple neuromata appeared. At the postmortem more than a thousand tumors were found affecting not only the peripheral branches and the sympathetic, but also the cranial nerves and the pneumogastric.
His most interesting phase is not that which he might assume under the lime-light of satirical or literary comparisons. The characteristic is after all the inessential. It marks a peripheral variation in the honest and sturdy lump. To catch only the heartless shimmer of individuality is to paint a costume without the body that supports it.
In some children, in the first two years of life, we find a definite and measurable increase in the irritability and conductivity of the peripheral nerves. The strength of current necessary to produce by direct stimulation of the nerve a minimal twitch of the corresponding muscle may be many times less than the normal.
We shall also meet other similar mechanisms as sources of sexuality. The state of desire for repetition of gratification can be recognized through a peculiar feeling of tension which in itself is rather of a painful character, and through a centrally-determined feeling of itching or sensitiveness which is projected into the peripheral erogenous zone.
At this stage the heart, which has already shown some trouble, becomes unable to force the blood properly against this enormous resistance of inelastic vessels and the blood pressure begins to fail as the left ventricle weakens. Edema, failing heart, perhaps aneurysms, peripheral obstruction, or hemorrhages are the final conditions in this chronic disease of arteriosclerosis.
