Not illustrated. 1841 edition. Excerpt: ...of food. Accordingly, the cceliac augments in volume, and becomes the chief point on which irritations from the brain impinge, and whence they are propagated to the latter. (See Lobstein, De Nervo Sympathetica. 1823. 47 et sey.) It has been said above, that the reflections or reverberations of the brain on the great sympathetic, and vice versa, would appear to be simple transfers of irritation. In what does this transfer consist? Here reference must be had to the fifth proposition, which states, that " all the functions, and even the most sudden changes in them, imply a change in the nutrition of the organs destined to perform them." The excitation of the brain consequent on the impression on the external senses, implies, therefore, a change in its nutrition; and this change modifies, and is modified by, the nutrition of the great ganglionic centre. The same, of course, applies, if the impression is made primarily on the last-mentioned part. It remains to inquire, afterwards, what is the nature of the change thus produced in the neuropathic or nervous condition. This physiological proem will render more clear the foundations of the theory advanced concerning the Essential Nature of nervousness. It will also go far towards forming the rationale of its particular symptoms. Perhaps the most desirable mode of exemplifying my meaning will be to suppose cases in which the operation of different causes has been efficient in disturbing the harmonious play of the two nervous systems, as they are commonly called. These causes have been stated to be either such as play upon the external senses and brain, including mental causes; or such as have their immediate or primary operation on the internal senses or ganglionic system. Of the former, let us...
