Introduction
Hydrofluoric acid, HF. Preparation: Dilute with water and potentize in silver vials to the fifth centesimal (Hering), (gutta-percha vials are now generally used).
Mind
Emotional. Great disposition, when alone, to repulsive fantastic imaginations, particularly in regard to persons with whom he stands in near relations, or with whom he is connected; it seems, for example, as though he must get red of all the servants, children must go out of the house, a betrothal must be broken off, a marriage should be dissolved, etc. Aversion to his business. He is more cheerful and vigorous (after eight and following days). Uncommonly gay disposition of the mind, the next morning. Feeling of perfect happiness within and without (after eight hours). Feeling of an interior happy state, never experienced before, next morning after the remedy. Feeling of highly enjoying everything (after twelve hours). All nature seems to smile, in the morning (after sixteen hours). Satisfaction, he desires no better state of things; all is right (after ten hours). Disposition to anxious ideas, frequently to such a degree that a perspiration breaks out (second day). He does not become anxious so easily as formerly. During the tottering sensation he has a decided though not anxious expectation, as if there was to happen something awful, but he feels no anxiety. Sensation as if dangers did menace him, but without being afraid; particularly during the pressure in the occiput, during the staggering, the pain in the bladder, etc. Ill-humor, lasting about twelve hours (after eighteen hours). During the fourth week very irritable towards people, even to the greatest hatred, which he does not hesitate to give vent to in words, but as soon as he sees them everything is forgotten, and he has an entirely different opinion of them. This does not arise either from hypocrisy or cowardice, but it is a suddenly altered view; mentally the same feeling which occurred to him physically during coryza (Secale S. 139). Whilst considering what might happen he gets into a most ungovernable anger, but only in his thoughts; several times during the first days. Easily displeased for half a day (after fourteen hours). In the evening he is very discontented; he looks at everything in the worst light; in the morning after a restless night, his temper is very cheerful and joyous. He remembers his experimentation only with horror and aversion, particularly the sensitiveness of the region of the stomach to pressure (after several weeks), in one who has made numerous provings. The least trifle is with him sufficient to show a bad temper in his features and motions, in ten hours; disappears during the next twelve hours. Indifferent, taking no interest in a very sick patient. Intellectual. He has great difficulty in fixing his attention upon anything. A more difficult comprehension of philosophical works; on the other hand all facts appear clearer to him. On making his notes he mistakes right and left, a circumstance that does not easily happen to him (second day). Every morning a peculiar rush of memory, so that a number of symptoms come to him which he had had the day before during the whirl of practice. Though his memory (for symptoms, etc). is good, yet he daily writes December instead of August (second week). Forgetful; he does not recollect sometimes the most common things. He forgets every evening to wind up his watch (second week). If his ideas are interrupted by other thoughts he is unable to recall the former, or at least only slowly and stupidly.

When rising from lying, vertigo, which lasted also when walking or sitting; afterwards eructations and slight nausea; in the morning. General Head. Determination of blood to the head, with heat in the forehead, gradually increasing to a headache in os frontis (after a few minutes). It appeared to him to proceed from the throat to the head; he felt as if he would be struck by apoplexy; a kind of determination of blood to the head and loss of consciousness; he could not recollect where he was (after smelling the acid). A stunning sensation in the head, mostly in front, immediately. Dulness in the head, in the morning until breakfast (from third to eleventh days).

Contractive pain, first in the head, then beneath the right scapula. Headache, with nausea and vertigo. Pressure in the head from within outward. Pressure in the brain, extending from below upward. Headache from the nape of the neck upwards, a dull pressure; it appears to proceed from the nape of the neck through the center of the head towards the forehead; it concentrates gradually more towards the left, as if a throbbing would arise there (two hours after fifth dose). A kind of shaking in the head, particularly in the back part of it, and more towards the right; a first whilst sitting, then particularly on every quick, short movement, or rising, turning, during walking, in the forenoon after 10 o’clock (first week). After breakfast the pains cease, except in the head, on quickly moving it from one position to the others, which continues the whole day (second day). Forehead. Painful determination of blood to the forehead, like a quick jerk, at the beginning of walking after standing, not after sitting; in the evening (after three or four hours).

Heat in the forehead, increasing to a headache. Compressing pain in the right frontal protuberance (after fifteen minutes). Headache in forehead and temples. Headache in the upper part of the forehead and vertex, towards the right (after five minutes). Headache in the left side of the forehead, in the evening.

Pressing pain in the forehead, on stooping, also pressing on the right eye (third day). Shooting pain in the left side of the forehead. Temples. Pain in the left temple, proceeding from within. Severe pressure in the left temple (after two hours).

Painful tension in the right side of the head. Slight drawing in the right side of the head. A violent pressive pain in the left half of the head in the course of the coronal suture (next morning). Sharp darting pain from near the posterior superior angle of the right parietal bone to the mastoid process of the right temporal bone; the pain was different from any other; much worse than a prolonged electrical shock or compression of the ulnar nerve (after three days). Sharp, shooting, undulating pain; it arises on the left side, about the middle and near the sutura interparietalis, and proceeds with the quickness of lightning to the left temple near the exterior part of the orbital cavity; this pain shoots about for two seconds, but to undulation lasts a little longer, and it is only when the undulation is nearly over that the mind takes cognizance of the whole of it; the shooting and painful undulation and the quickness, are of such a nature as to produce immediately in the mind a very disagreeable idea of some impending danger; the undulation may be best compared to that of the streak left on the wall, in darkness, by the friction of a phosphoric match. Occiput. From the nape of the neck to the occiput, a feeling like a warm breath. Dulness of the occiput only, immediately after repeated doses. Dulness towards the right in the occiput (after one hour). In the morning, shortly after awakening, a cramp like pain in the very lowest part of the occiput towards the left. F.
