The method that we believe to be suggested by the foregoing considerations would be more complex, but, we think, at once more effectual and less inconvenient. It may be stated in the following formula: "Secure the predominance of the cerebro-spinal system over the activity of the ganglionic."
There are also some of the nerves of voluntary motion that are mixed with these, which enable the mind to stop respiration, or to regulate it to a certain extent. But the mind has no power to stop it for any great length of time. There is another large and important system of nerves called the sympathetic or ganglionic system.
But beyond a certain point in the ascending scale, the exactness of this correlation ceases. The muscles and bones are smaller; yet the structure of the cerebro-spinal organs, especially the brain, becomes more elaborate; and hence the control exercised over the functions of the ganglionic system is more complete, although the relative size of the two systems is not much changed.
The nervous system, though in many respects a unit, consists of two great sections, called respectively, the ganglionic system, and the cerebro-spinal; the latter formed by the brain, the spinal cord, and the medulla-oblongata, that connects them; the former, constituted by smaller masses of nervous matter distributed in three ways: First, in a double chain lying on each side of the spinal cord, from the upper part of the neck to the pelvic cavity that terminates the trunk.
Caxton to walk with her to market. By the way they passed a sward of green, on which sundry little boys were engaged upon the lapidation of a lame duck. It seemed that the duck was to have been taken to market, when it was discovered not only to be lame, but dyspeptic, perhaps some weed had disagreed with its ganglionic apparatus, poor thing.
An excessive stimulation of those fibres which enter into the ganglionic masses, would have an effect similar to that of excessive stimulation directly addressed to the cerebro-spinal system, and the blood-vessels would be not only dilated, but paralyzed.
If we now turn from the comparative study of psychic life in different animals to the question of the organs of this function, we receive the answer that in all the higher animals they are always bound up with certain groups of cells, the ganglionic cells or neurona that compose the nervous system.
These are but the subsidiaries; for as you may remember, my dear Kitty, that I have said before, we can never keep the system quite right unless we place just in the centre of the great ganglionic system, whence the nerves carry its influence gently and smoothly through the whole frame, The Saffron Bag!" Rubruquis, sect. xii.
It is not, therefore, stimulation of the intellect, but excitement of the feelings, that can be shown from physiological data to have an injurious effect upon the vaso-motor nerves of the uterus, or the ganglionic nerves of the ovaries, or, in other words, can be concerned in the production of uterine hæmorrhage. To be just, however, it must be admitted, that still another view is possible.
These facts, and many others that might be quoted, are pertinent to our subject, on account of the influence exercised over the ganglionic centres by the development and functional activity of those of thought. Stimulation of the cerebral hemispheres is one of the most powerful means of counteracting paralysis of the vaso-motor centre, with all its consequences.
