Every piece of animal flesh is saturated with these excrements of the cells in the form of uric acid and many other kinds of acids, alkaloids of putrefaction, xanthines, ptomaines, etc.
That is one of the effects of the mydriatic alkaloids, of which this is one. The ancients were familiar with several of its peculiar properties, as they knew of the closely allied poison hemlock. "Many of the text-books at the present time fail to say anything about the remarkable effect produced by large doses of this terrible alkaloid.
In general, the hydrogen addition products were found to be more active than the simple base, an observation entirely in accord with the theory formed by Wischnegradsky, and by Konigs, as the result of the study of the decomposition products of the alkaloids, viz., the alkaloids are in general hydrogen addition products of pyridine and quinoline, or of the two bases combined. Thus Prof.
Taking up the volatile alkaloids, we find with regard to conine, first, that the action of methyl iodide shows it to be a secondary amine, that is, it restrains only one replaceable hydrogen atom of the original ammonia molecule. Its formula is therefore C H NH. From conine can be prepared methyl-conine, which also occurs in nature, and dimethyl-conine.
Whether a practical commercial synthesis of quinine will follow is another matter, but it is within the bounds of possibility, or perhaps even of probability. It must not be supposed that no syntheses of alkaloids have been effected as yet. By heating butyl-aldehyde with alcoholic ammonia is formed paraconine, an alkaloid isomeric with the natural conine, but differing in physiological action.
I think that explains what the chemist discovered; no more, no less. The cyanide theory does not fit." "One chemist hinted at nux vomica," volunteered the coroner. "He said it wasn't nux vomica, but that the blood test showed something very much like it. Oh, we've looked for morphine chloroform, ether, all the ordinary poisons, besides some of the little known alkaloids.
Professor A. Vogel, in a communication to the "Sitzungsberichte der Munchener Akademie," brings into prominence the fact that the hemlock plant, which yields coniine in Bavaria, contains none in Scotland. Hence he concludes that solar light plays a part in the generation of the alkaloids in plants.
And then come those false friends, those Thug helpers, the alkaloids that stifle natural fatigue and kill rest black coffee, cocaine " "I see," said Isbister. "I did my work," said the sleepless man with a querulous intonation. "And this is the price?" "Yes." For a little while the two remained without speaking. "You cannot imagine the craving for rest that I feel a hunger and thirst.
At the same time that this general agreement to consider these bases as the starting point in the endeavor to effect the synthesis of the natural alkaloids had been arrived at by chemists, it was thought well to look into the question whether these bases and their immediate derivatives had any therapeutic value of their own.
The use of this plant, containing obscure alkaloids of the katinacetate class, constituted his only vice if you can call a habit such as this vice, that works great well-being and that leaves no appreciable aftermaths of evil such as are produced by alcohol or drugs. For a few minutes the Master sat quite motionless, pondering.
