However its use should be well considered as it would not suit all cases. It may be Sub-Asst. Surgeon, safely used in cases of insomnia due to cardiac or respiratory Central Lunatic Asylum, Agra. diseases, mania, hysterical excitement, melancholia and in the later stages of adynamic fever, etc. It is generally used in Asylum practice and is considered to be a valuable remedy. It should be given at bed time in 1 to 4 dram doses. Major A. O. Wright gives it in 2 to 3 dram doses when the pulse rate is rapid and the arterial tension is high, but where the arterial tension is low, he administers it in 10 to 15 minimum doses. The only drawback in the use of Paraldehyde is its nuseous taste and unpleasant ethereal odour, which it imparts during its elimination by the breaths. Its pungent disagreeable taste may be disguised by mixing it with Syrup or Tr. of orange and peppermint water. Large doses should be emulsified with compound Tragacanth powder. Dr. W. J. Corrindon of Lunatic Asylum, Agra, likes to add sufficient water to dissolve all the Paraldehyde. Chloral Hydrate also acts quickly and therefore should be given at bed time. Its cardiac and respiratory depression should be noted and therefore should not be given to old people with fatty heart or lung diseases or to delicate or cons- titutionally weak persons. Its action is very satisfactory in cases of alcholic insanity. In doses of 15 to 20 grains, it induces a refreshing sleep, which thus obtained not infre- quently leads to the repeated use of the drug and thereby induces the chloral-habit. It should be prescribed with Syrup Ginger, as it covers its pungent taste very nicely. It may be given by rectum or subcutaneously. Bromides of Potassium, Sodium or Ammonium are suitable for mild cases. Of these salts Pot. Bromide easily ranks first and should be given in 3ss?3ii doses, with camphor or chloroform water. Some people speak of better results when the three salts are combined. Of all the sedatives they are probably thf least harmful and can be administered for a longtime If given in full doses for a long time, they some- times tend towards dementia and derange digestion. Acute spots, etc., should be controlled by the admixture of 2 or 3 ms. of Liq. arsenicales. The Bromides are also usefully combined with other Soporofics such as Tr. Hyoscyami 3ss?3ii or Tr. Cannabis Indica 3ss?3ii or with Tr. Digitalis 3ss, which in such doses seems to have a calming effect on the central circula- tion. Pot Bro. with Liq. morphine acts as a very nice sedative and hypnotic after surgical operations. I have seen its use with marvellous results after surgical operations in 6 or 7 Sa.dar Hospitals of these Provinces. The Bromides also prolong and intensify the effect of Chloral Paraldehyde and Amylene Hydrate when prescribed with them. Bromides may be administered by the mouth, Rectum or hypodermicallv. Hyoscine, Hydrobromate or Sr.onolomine should be used hypodermically in doses of g. 1/100?g. 1/75. It is a powerful motor depressant which should only be used to emergency purposes and is then sometimes given with Morphia. In Asylum practice I have seen its wonderful calming effect in cases of violent maniacal excitement. Hyoscine g. 1/75 and Duboisine g. 1/100 have similar actions though less pronounced. is Sulphonal dose g. xx-xl is a tasteless powder and not very soluble and therefore should be given in hot milk or hot water about 4 hours before retiring to bed It has a cumulative action and keeps a patient quiet a next day and if repeated on the second night, its effects are more pro- nounced. It is a motor depressant and therefore it is very useful in mania. It suits old people well. Patients who are given this drug should however be induced to drink as much fluid as possible and the bowels should be kept open. Its combination with Potassium Bromide may be warmly commended 10 to 20 grains of sulphonal with 20 grains of Bromide in a cup of warm broth, milk or chocolate should be taken about 4 hours before bed time. Medinal. Triona and Veronal are fairlv tasteless powders and are all hypnotic in frequent use. They should be given in doses 5-10, 15-30, and 5-10 grains respectively. .

  • Nietzsche and Psychedelics – Peter Sjöstedt-H –
    Antichrist Psychonaut: Nietzsche and Psychedelics – Peter Sjöstedt-H – ‘… And close your eyes with holy dread, For he on honey-dew hath fed, And drunk the milk of Paradise.’ So ends the famous fragment of Kubla Khan by the Romantic poet, Samuel Taylor Coleridge. He tells us that the poem was an immediate transcription of an opium-induced dream he experienced in 1797. As is known, the Romantic poets and their kin were inspired by the use of psychoactive substances such as opium, the old world’s common pain reliever. Pain elimination is its negative advantage, but its positive attribute lies in the psychedelic (‘mind- revealing’)1 state it can engender – a state described no better than by the original English opium eater himself, Thomas De Quincey: O just and righteous opium! … thou bildest upon the bosom of darkness, out of the fantastic imagery of the brain, cities and temples, beyond the art of Phidias and Praxiteles – beyond the splendours of Babylon and Hekatómpylos; and, “from the anarchy of dreaming sleep,” callest into sunny light the faces of long-buried beauties … thou hast the keys of Paradise, O just, subtle, and mighty opium!2 Two decades following the publication of these words the First Opium War commences (1839) in which China is martially punished for trying to hinder the British trade of opium to the Chinese people. Though opium, derived from the innocent garden poppy Papavar somniferum, may cradle the keys to Paradise it also clutches the keys to Perdition: its addictive thus potentially ruinous nature is commonly known. Today, partly for these reasons, opiates are mostly illegal without license – stringently so in their most potent forms of morphine and heroin.

The data included relate to the body fluid concentrations of substances in normal or therapeutic situations, concentrations in fluids and tissues in instances of toxicity and the known metabolic fate of these substances in man. Brief mention is made of specific analytical procedures that are applicable to the determination of each substance and its active metabolites in biological specimens. It is expected that such information will be of particular interest and use to toxicologists, pharmacologists, clinical chemists and clinicians who have need either to conduct an analytical search for these materials in specimens of human origin or to interpret 30 Amberwood Parkway analytical data resulting from such a search.
