These compounds had a very surprising febrifuge action, without any unpleasant after effects or local disturbances. The most active workers in the field of synthetic formation of the alkaloids have been Wischnegradsky, of St. Petersburg who, unfortunately for science, died at an untimely age in 1880 Königs and Fischer, of Munich, and Ladenburg, of Kiel.
If a volatile alkaloid, add a few pieces of calcium chloride to ethereal solution to absorb the water; draw off the ethereal solution with a pipette, allow it to evaporate, and test the residue for the alkaloids, conine and nicotine.
The remaining acid watery liquid, holding the other alkaloids in solution or suspension, is made strongly alkaline with soda, mixed with four or five times its bulk of ether, chloroform, or benzole, briskly shaken, and left to rest. The ether floats on the surface, holding the alkaloids, except morphine, in solution.
Sure enough, as I had expected, Kennedy was in his laboratory. As we entered he was verifying his experiments and checking over his results, carefully endeavouring to isolate any of the other closely related mydriatic alkaloids that might be contained in the noxious fumes of the poisoned tobacco.
Certain products are common to the whole vegetable series, but others, far less numerous, are prepared in special laboratories. Each genus, each species has its trade-mark. Here essential oils are manufactured; here alkaloids; here starches, fatty substances, resins, sugars, acids. Hence result special energies, which do not suit every herbivorous animal.
The synthetical researches which I have undertaken with a view to explain the constitution of atropine have shown me the necessity of studying the connection of atropine with the other alkaloids, which have an analogous physiological action.
British manufacturers, on the other hand, held their own in the production of certain kinds of drugs, such as the alkaloids, gaseous anaesthetics, and some inorganic salts of bismuth and mercury.
The patients themselves, however, followed their own inclinations which is a reprehensible way that patients have so that we remained neglected, with our modern instruments and our latest alkaloids, while he was serving out senna and calomel to all the countryside.
As in the case of most of the poisonous alkaloids, aconitin does not produce any decidedly characteristic post-mortem appearances. There is no way to distinguish it from other alkaloids, in fact, no reliable chemical test. The physiological effects before death are all that can be relied on.
"Of all the dangers to be met with in superstitious countries, these mydratic alkaloids are among the worst. They offer a chance for crimes of the most fiendish nature worse than with the gun or the stiletto. They are worse because there is so little fear of detection. That crime is the production of insanity!"
