arsenicum, hyoscyamus, of kali bromatum, opium, phosphorus, stramonium, of lachesis, platina, and antipyrin &c., are all accompanied by distress, by fear, and present a terrifying character. Those of ambra, belladonna, agaricus, cimicifuga, sulphur, &c., are attended by a markedly excited state, with tendency to react to the visions. Valerian has somewhat variable hallucination, agitating, but not affecting the patient greatly. The hallucinations of cocaine have always the character of persecution; those of canabis indica are attended by anxiety; the patient speaks to the appearances; and they also have this distinctive sign, that they modify the normal proportions of time and space. In the same category is platina, which magnifies things with the sense of pride; while sulphur beautifies them. Cimicifuga and opium have visions of rats and mice, the first with more agitation and mania, the second more fantastic, with fixity of ideas. The ecstatic tendencies of agaricus should be noted, the gloom of lachesis, the fear of death of aconite, lachesis and arsenicum and the sense of guilt of kali bromatum. Lastly, in diagnosing the remedy, natrum salicylicum should be thought of. It often answers to the onset of mental derangement, and in this case would have covered the noises in the ears and the vertigo, though the delirium of this last remedy is somewhat sullen and it also presents a state of lassitude and drowsiness, in sharp contrast to the wakefulness and even insomnia observed in the patient. In these conditions, and the actual state of our Materia Medica, anhalonium constituted the simillimum and was what cured the patient.
I would, however, add that, according to my personal experience, the troubles set forth in our repertories under the rubric Mentality are the more easily cured by our remedies if definitely linked with an organic condition [auto-intoxication or coenaesthesia]. In the case in question, the sight and hearing being affected by general organic causes, the symptoms lost in effective value. On the contrary, when the psychic, sentient element dominates the pathogenesis, cure by medical means alone is more difficult and elusive. In such cases, cure should always be attempted in accordance with the law of similars; but aided by psychic and psycho-analytic methods, which I always employ in such cases, following up, by observing the sequence of action and reaction, the chain of events which has led the patient from normal health to the actual morbid state.
