He walked over and pulled down a well-thumbed standard work on toxicology, turned the pages, then began to read aloud: Pure aconitin is probably the most actively poisonous substance with which we are acquainted and, if administered hypodermically, the alkaloid is even more powerfully poisonous than when taken by the mouth.
This chewing of the Aram-root is the very being of kava as a beverage, for it is a ferment in the saliva that separates alkaloid and sugar and liberates the narcotic principle. Only the healthiest and loveliest of the girls are chosen to munch the root, that delectable and honored privilege being refused to those whose teeth are not perfect and upon whose cheeks the roses do not bloom.
Coupled with this distortion of the face, this Hippocratic smile, or 'risus sardonicus, as the old writers called it, what conclusion would it suggest to your mind?" "Death from some powerful vegetable alkaloid," I answered, "some strychnine-like substance which would produce tetanus." "That was the idea which occurred to me the instant I saw the drawn muscles of the face.
Shall I ever forget the look which came over his face when the first warning pangs told him that the poison was in his system? I laughed as I saw it, and held Lucy's marriage ring in front of his eyes. It was but for a moment, for the action of the alkaloid is rapid.
Digest the contents of the stomach in cold distilled water and very dilute sulphuric acid; strain, filter, and press residue. Evaporate the filtrate to half its bulk, digest with alcohol, and evaporate alcohol off in a water-bath. Remove ether and allow it slowly to evaporate. Test resulting alkaloid. Tests. No change of colour with the mineral acids. White deposit with corrosive sublimate.
But with this granted, the simplest alkaloid formulas, those of conine, C H N, and nicotine, C H N , still showed that the amine molecule contained quite complex groups of carbon and hydrogen atoms, and the great majority of the alkaloids the non-volatile ones contained groups in which the three elements, carbon, hydrogen, and oxygen, all entered.
Piperidine hydrochlorate, also, when heated with excess of bromine to 180° C., yields dibrompyridine. Sinapine, the alkaloid which exists as sulphocyanate in white mustard seed, yields, under the same reaction as that applied to atropine and piperine, quite different results.
But this man knew she was always there, thinking, watching, eagerly planning in aid of any new scheme in the long fight for freedom. "The alkaloid was present, that is certain," he told Kennedy. "My wife has told you that. It was scientifically proved. There is no use in attacking that."
When you have to resume the drug, go cautiously. He was obliged to eat a few mouthfuls of sago before the alkaloid could act upon his nervous system. I need only point out the significance of this indication.
The second head comprises but a single alkaloid, variously called paramorphta or thebain. Its chief action appears to be upon the spinal nerves, and there is reason to suppose it a poison of the same kind as nux vomica without the concentration of that agent.
