5. The Nervous Energy is stopped by a tight Ligature or by the transverse Incision of a Nerve, although its divided Parts are thereafter placed in contact with each other; whereas the Electrical Fluid or the Fluid excited by the Metals, passes readily, downwards or upwards, along a Nerve which has been tied or cut.
6. After the Limb of a living Animal has been amputated, frequent Convulsions of the same Muscles may be excited by applying Mechanical or Chemical Stimuli to its Nerves; whereas Electrical Matter discharges itself suddenly.
Hence I conclude,
1. That the Fluid, which, on the application of Metalline Bodies to Animals, occasions Convulsions of their Muscles, is electrical, or resembles greatly the Electrical Fluid.
2. That this Fluid does not operate directly on the Muscular Fibres, but merely by the Medium of their Nerves.
3. That this Fluid and the Nervous Fluid or Energy are not the same, but differ essentially in their Nature.
4. That this Fluid acts merely as a Stimulus to the Nervous Fluid or Energy.
5. That these Experiments have merely shown a new mode of exciting the Nervous Fluid or Energy, without throwing any farther or direct Light on the nature of this Fluid or Energy.
