In order to find out these facts, Prof. Bose took a piece of metal which showed full vigor of sensitiveness and so was considered healthy, and treated it with a moderate dose of oxalic acid, which is a powerful poison. The needle of the galvanometer instantly indicated a spasmodic flutter; the sensitiveness of the metal more and more feeble, till it seemed almost to die away. At this stage, a powerful antidote being applied, slowly and gradually the sensitiveness began to revive, and in time became as active as when the metal was not poisoned. The treatment of another piece of healthy metal with a strong dose of the same poison resulted in violent spasms, with rapid enfeeblement of sensitiveness, which soon vanished altogether. After a proper interval the antidote was tried in vain; the piece of metal was killed forever. The results of experiments with different metals and different poisons were the same; but all poisons not being alike in their action upon animal matter, the same is true of their action on metal, absolutely and undoubtedly. In some cases, however, after all traces of poison had been removed by the counteracting influence of stimulating acids, the poisoned metal was eventually reanimated; which meant that the metal was not really killed, but was merely in a state of suspended animation. The most striking feature of the discovery in this connection is, that the very poison which kills both animal and metal is itself endowed with life, which shows itself by indications of irritability and sensitiveness, and which can itself be killed. Here is another significant point in regard to the operation of poison on both an animal and a metal. In the case of an animal the operation is twofold; first, the actual death process, lasting from a few minutes to several hours; secondly, the purely nervous effect which manifests itself in the form of spasms, paralysis or other symptoms, and which is developed much sooner, sometimes instantaneously. Prof. Bose has discovered the same phenomenon in metal. Under the effect of some powerful poisons there was instantaneous spasm shooting through the metal long before the corrosive action of the acid could penetrate beyond the surface. Professor Bose has proved in his book that all these phenomena with every single variation exist as much in the vegetable kingdom as in the animal and mineral. Indeed, the three kingdoms of matter, the animal, the vegetable and the mineral, are, says the Professor, but one in essence and the physiological distinction between so-called organic and inorganic matter, of which man and metal are but types, is based upon a false and unscientific assumption. Prof. Bose dedicates his book to his countrymen, the Hindoos, because, he says, his discovery is a discovery made millions of years ago by the Hindoo sages, who proclaimed the unity of the universe in essence and construction, as well as in the laws that govern it.
