Even while triturating the drug in my mortar, the most striking effects were produced by the simple emanations ascending from it. This phenomenon, however, is observed whenever I cause a somewhat active drug to be triturated in the mortar. The symptoms which I have collected, are not a great many, but they can be depended upon. Most of the symptoms were experienced by several provers, and some of them have already been confirmed by treatment, among which may be mentioned the oppression in going up-stairs, the vesicular eruption on the feet and the deafness. This last symptom is of great importance on account of its being so obstinate. For pulmonary affections the poison of the cobral may likewise prove a valuable remedy, especially for the second stage of phthisis, characterised by bloody cough and derangement of the digestive functions. It may likewise be serviceable in mental alienation and cutaneous eruptions. The special action which this poison seems to exercise on the right side, the paralysis, the lancinations, have appeared to me worthy of attention. The gyratory motions, the desire to move to and fro, the scaling off of the epidermis and several symptoms relating to the disposition and the mind, seem to deserve the attention of the philosophical physician. There certainly exist remarkable analogies between the symptoms of the cobral and those of the lachesis. The differences, however, are sufficiently numerous to refute the doctrine that all serpent-poisons act almost alike and that the cobral, for instance, may be resorted to as a perfect succedaneum of the lachesis. I am convinced of the contrary to such an extent that it is my belief that the poison of serpents alone would, if sufficiently proved, furnish the safest and most rapid means of combating all human infirmities. Every epoch in the history of the world is undoubtedly possessed of therapeutic means which are more particularly homœopathic to the general character of the ruling maladies. Hence it is probable that when the human species shall have been freed from the miasms which now undermine its vitality, the simple flowers on the fields will be sufficient to control the remaining indispositions. Whereas we, unfortunate heirs of the chronic miasms of all ages, lepra, scrofula, syphilis and a host of other subtle plagues, are compelled to employ the most frightful agents in order to meet the intensity of our diseases.
