![. \ IIMV A wound es develops neither pain nor convul sion in ila first instance; they do not transmit sensations to the I nor the i of the brain to the organ The ganglionic nen dy preside over the internal actions that are not directed by the cerebral centre. Blended with the capi system of the viscera, their us;- is to regulate and transmit stimulation from one part r, according to tin- wants of the creating power ; that is to say, they arc particularly subservient to the vital chemistry. The ganglionic nerves concentrate the stimulating influences oi the cerebral nerves, and make them subservient to the actions dial are inde- pendent of the centre of perception, i [ence the will can neither with- draw nor even control the stimulation it has once transmitted to them through the agency of the functions of relation. The ganglionic nerves render the \ itaJ force of the animal subsen ienl to the living chemistry, notwithstanding the influence of the will; and when the amount of this force is no longer sufficient to the perform; ot the two great orders el' functions, these nerves divert it from the functions of relation and concentrate it in those of nutrition : they ope- rate this diversion by accumulating the vita] force and the fluids along with it in the vessels of the viscera, and especially in those oft he lira in ; this is what produces sleep. \\ hen irritation is predominant in the viscera, the ganglionic nerves cause it to How hack to the organs of relation through the medium of the cerebral nerves with which they communicate in these same \ iscera ; and it is no more in the power of the will to prevenl this irritation, than to take hack from the viscera that which it has once transmitted to them. The centre of relation, under the influence of the viscera, excites, with <»r without the concurrence of the will and the knowledge of the animal, certain actions in the locomotive organs which arc in direct pro- portion to the viscera] irritations, and which terminate only in the ces- sation of those irritations, or in the engorgement, compression, and disorganization of the brain. Whenever a stimulation isexcited mtheeconomy capableof giving •''!- ' thj cerebral nerves, it is transmitted to the centre ofrelation, wlll,'!l may. j ience, execute certain movements, without the consciousness or will ofthe animal. The phenomena, then fore, which give the idea of consciousness are discontinued, whilst the perception and reaction of the centre of relation are continued.
