blossoms; but that free from oxygen, such alkaloids yield either a most sickening, disgusting smell, or a most agreeable aroma, which recalls that of the most delicately scented flowers; and it is suspected that such blossoms owe their agreeable smell to the poisonous ptomaine. The venomous essence of certain fungi, also, is nearly identical with the venom of the cobra of India, the most deadly of serpents. The French savants Arnaud, Gautier, and Villiers, have found in the saliva of living men the same venomous alkaloid as in that of the toad, the salamander, the cobra, and the trigonocephalus of Portugal. It is proven that venom of the deadliest kind, whether called ptomaine, or leucomaine, or alkaloid, is generated by living men, animals and plants. Gautier also discovered an alkaloid in the fresh carcase and brains of an ox, and a venom which he calls xanthocreatinine, similar to the substance extracted from the poisonous saliva of reptiles. It is the muscular tissues, the most active organs in the animal economy, that are suspected of being the generators or factors of venoms, which have the same importance as carbonic acid and urea in the functions of life, and are the ultimate products of inner combustion. And though it is not yet fully determined whether poisons can be generated by the animal systems of living beings, without the participation and interference of microbes, it is ascertained that the animal does produce venomous substances in its physiological or living state.
