4. Dr. J. C. MORGAN, who reports the above provings, himself tasted the cork of an opened bottle of the syrup on Feb. 19th, 1889. On 21st symptoms began to appear, and continued to do until April, when, “as weather became milder,” they subsided. [We must content ourselves with referring to this observation. – EDS.] (Ibid.)

5. D. LA PLANT began with 5 dr., afterwards increased to 10 dr. doses of same syrup. Woke about 2 a. m. with rumbling and much movement in bowels, without pain. Next day continued taking medicine; no symptoms till evening, when he became drowsy unusually early, so that he was compelled to retire. Awoke again at 2 a. m. with same loud rumbling and gurgling in bowels, preventing sleep for some time. 3rd day – Breakfasted as usual and went to work, but did not feel well; had a dull headache. At 10 a. m. stiffness of jaws came on. which rapidly increased. At noon went to dinner, but could not eat on account of pain in maxillary joints. At 1 p. m. jaws were almost set, and any attempt to open them caused extreme pain. Alarmed, and thinking of tetanus, he took some aconite, with relieved at once. In evening face was sore and lame, and it remained so for several d. On 4th day, after dinner, was seized with colicky pain in epigastric region which continued for 30 hours; it was attended with frequent urination. On examination urine showed decrease of urea. During the proving bowels very much constipated (more so than usual). (Ibid., 1890, p. 228.)

ACIDUM OXALICUM (See vol, i, p.45.)

II. 9. B. K., aet, 19, took sixpenny worth of oxalic acid soon after a lunch of bread, cheese, beer and coffee. In 5 m. retching and copious vomiting, burning pains in throat and abdomen. The stomach was washed out several times; the vomit and washings were bloody. Half an hours later, grave collapse; pulse 48, small, irregular; respiration 10 – 12, superficial; skin covered with cold, clammy sweat; face livid and features sunken; pupils dilated. Patient opens his eyes when loudly spoken to and then falls back into his apathetic state; constant desire to vomit, but brings up mucus only – no blood. Hypodermics of camphor, hot coffee, brandy. At 8 p. m., 2 hours later, complains of great thirst, burning and stitching in abdomen, and then collapse returned in a most threatening manner, with cyanosis; dyspnoea; livid fingers and toes, and sensation altered in toes and tips of fingers. Stimulants relieved again, and pulse regained some volume; great restlessness with tonic and clonic spasms in upper and lower extremities. Patellar reflexes increased on both sides, a slight touch causing long – continued crampy motions. Achilles tendon reflex and periosteal reflex increased; when merely touching the left external malleolus, tendon of left tibialis anticus becomes prominent. Triceps tendon reflex and periosteal reflex of epiphyses of humerus also increased on both sides. Sensorium dull; patient reacts only on loud calls; pupils still dilated. At 9 p. m. spasms diminish in strength and frequency; sensorium more clear, realizes that he is in the hospital; severe pains in throat when talking or swallowing; pulse better; patient sleeps naturally, only interrupted by weak clonic spasms in upper and lower extremities. 10 p. m., abdomen soft; desires to urinate, but passes only 100 c. cm. of yellow, somewhat murky acid urine. Sensorium clear and replies freely, though with a hoarse voice and some exertion. 11:30, examination shows complete anaesthesia of tips of fingers and toes, of palmar surface of hands and plantar surface of feet. Incomplete sensibility of leg. Sensation in thighs and other parts of body normal, pulse 80; temp. 38.2 C. Pains in left lumber region and both legs: feet and hands feel as if asleep; great thirst, burning in mouth; sleeps but little during night. 2nd day – Passes spontaneously 150 c. cm. of acid urine, slightly bloody, leaving a thick Sediment; sp. gr. 1016; rich in albumen; epithelia and epithelial cylinders; red and white blood corpuscles; colouring matter of blood; no sugar; small quantities of oxalic acid crystals, amorphous, of envelope and so – called dumb – bell form. After standing 36 hours, microscope shows copious, whitish, shining crystals of oxalic acid and of oxalate of lime in many forms – insoluble in acetic, soluble in sulphuric acid. In evening pains in renal and vesical region, a crawling sensation over whole body, especially in both lower extremities. Several times during day painful spasms in muscles of left calf; no appetite; tendency to vomit; profuse perspiration on hands and feet; discharges 300 c. cm. of dark, jumentous urine; tongue heavily coated; pulse 84, temp. 38.6 C. 3rd. d. – Urine 400 c. cm., much albumen, many cylinders; sensory disturbances continue; no spasms; dulness in head, patient feels as if he had been drunk. Urine 600 c. cm. no crystals; temp. normal; feet and hands dry. 4th day – Urine 900 c. cm.; less albumen and fewer cylinders; general improvement; sensory and reflex phenomena disappear; slight gastric disturbances still, but well enough to be discharged. (The lunch taken before the suicidal attempt and the prompt washing out of stomach probably saved the patient’s life.) (KOHLER, transl. in Hom. Phys., Sept., 1889.)

ACIDUM SALICYLICUM (See vol.iv, p.15.)

In vol.i p.70, l 13 deom borrom, doe “SALICINUM” read “SALICYLICA”

1. 15. Dr. A. M. CUSHING took 5 gr. of 1x trit. daily for 5 day, when following symptoms appeared: – Nov. 23rd. – Distressing pain in middle dorsal vertebrae, with desire to press back against something. 24 th. – 0 Some distress in back burning day 2 p. m., sudden lame pain in left ankle when beginning to walk.

At times pain in 3rd toe of left foot nearly compelling him to scream. At times pain in muscles of left thigh. For several day hard pain in right arm above elbow. During whole proving burning sensation in region of heart. A carbuncle appearing on back of neck led him to scream. At times pain in muscles of left thigh. For several day hard pain in right arm above elbow. During whole proving burning sensation in region of heart. A carbuncle appearing on back of neck led him to scream. At times pain in muscles of left thigh. For several day hard pain in right arm above elbow. During whole proving burning sensation in region of heart. A carbuncle appearing on back of neck led him to discontinue proving. (Publ. of Mass. Hom. Medorrhinum Soc., v, 30.)

11. 17. A young man of 22, convalescing from pneumonia, was given 5 gr. 3 times daily as a “tonic.” He was now taken with severe pain in right foot, seemingly in toe joint. He put foot into hot mustard and water, but it did not relieve; suffered all night; pain then went to above knee, then to shoulder and arm. The doctor gave Dover’s powders for the pain, continuing the “tonic.” Pain lessened, but at n. grew worse again, very severe and sharp in shoulders and both limbs above knees. Next forenoon pain in bowels, which more Dover’s powders did not relieve. At n., pain in left side about heart; distress for breath; palpitation; could not rest. Was very weak next day, and, beginning to be alarmed, Dr. Donaldson was sent for. He found “congestion of heart,” pulse very irregular. The acid was stopped, and nux vomica given, and patient began to improve at once. (Ibid.) Dr. Althaus describes a skin eruption, beginning like herpes but then assuming the appearance of pemphigus, spreading all over face and body, with aphthae in mouth and fauces, and haemorrhage from bowels, as resulting from the drug. He does not say how it was given or in what disease



The cases of poisoning, Nos. 2 to 4, taken from the Berlin klin. Wochenschrift, are referred by that journal to a Dutch periodical, the Nederl. Tijdschrift voor Geneeskunde, 1880, No. 16. To this we have not been able to get access. In the Bull. de la Soc. de Therapeutique for 1883, however (p.3), Dr. Dujardin – Beaumetz mentions the cases, and gives an account of Dr. Meyer (s symptoms during life, which the German version omits. They were as follows: –

The toxic effects began to show themselves in 1/4 h. After 4 h. Dr. Tresling found him pale; pulse small and irregular, but not accelerated; skin cold; pupils contracted. There was sense of burning in mouth, and of constriction from throat to abdomen; patient complained of praecordial anxiety, and of heaviness and weakness of limbs, especially legs. Pupils suddenly dilated, and vision was lost, but it returned as they became once more contracted. Vomiting was excited, but there soon came on acute congestion of head, and therewith convulsions and stertorous breathing. M – then complained of deafness, and of humming now in one, and now in other, ear. After a subcutaneous injection of ether, pupils dilated again, and vision was lost; then vomitings recurred, and prolonged and violent convulsions. A second injection was made, but patient could not be restored to consciousness; pupils did not react to light; respiration became slow and laboured, and spite of electricity more and more difficult; heart grew feebler, and in 5 hours after taking poison M – was dead. P. M. showed great pallor of skin and muscles, while internal organs were strongly congested, save colon, rectum, and bladder, and bladder, which were anaemic. Heart was in diastole. At certain spots in arachnoid exudation was found, and there was in diastole. At certain spots in arachnoid exudation was found, and there was bloody serum in ventricles, and a sanguineous exudation on the choroid plexus.

II. 14. The patient, Miss M -, aet. 24, took through mistake Zss of the tinct. aconiti red., which was followed i 20 or 30 m. by a sense of warmth in stomach, nausea, and oppression of breathing. Shortly after this followed numbness, tingling, and slight muscular weakness. She did to attribute her feelings to the drug, and in 1 hours from the time it was taken (4:30 p. m.) the dose was repeated. She started soon afterwards to walk a distance of two miles, and did not complain until about half way. On reaching her destination she began to stagger, and was soon completely prostrated. Her voice became different portions of body, but particularly in joints. I was set for, poisonous dose of aconite, I administered the usual emetic, which was quickly arrived. I found the patient in the following condition: Axillary T. 97.1/2; P. 32; right 10. Pupils dilated, extremities cold, loss of consciousness, extreme pallor of face with expression of great suffering, and there was a twitching of the mouth and eyelids. Emesis which had an odour of alcohol. The retching continued, and her condition each moment grew worse, the pulse becoming frequent and irregular, and respiration more difficult. By consent of Dr. S. I injected hypodermically fifteen mins. Magendie’s sol., just after which having slight convulsion. There was a spasmodic sol., just after which having a slight convulsion. There was a spasmodic contraction of the laryngeal muscles, respiration ceased, and the pulse was imperceptible. Dr. S. did not observe me inject the morphia, d remarked that if I woman; respiration had ceased, the feeblest pulsation could not be detected, the body was cold to the touch, and we had every evidence of impending dissolution. We had lost all hope in the case, but were endeavouring to detect a feeble impulse of the heart, when suddenly and to our surprise the pulse sprang up, about the rate of 40 per m. the laryngeal muscles were relaxed and respiration began. Very soon the cheeks were flushed, and heat returned gradually to the extremities. The thermometer was again placed in the axilla, and registered 98.1/2. The retching continued, and in 1/2 hours the pallor returned, there was general muscular tremor, and the pulse became frequent and irregular as before. Ten mins. Magendie’s sol. were injected, and an enema containing 20 gr. carbonate of ammonia and one ounce of brandy. She soon rallied as before, this time recovering consciousness; and complained of cephalalgia, burning sensation in the stomach, and severe pain in different parts of body. At 10 p. m. I injected ten mins. more Magendie’s sol., which seemed to quiet her, and at 12 she was asleep. The bladder had been evacuated four times since 8 o’clock. – 15th, 6 a. m., temp. 99; pulse 80. Has vomited only after the enemas, which were repeated at intervals of 2 h. She complained of great muscular soreness, and movement of the body is painful. She is very weak, her grasp being scarcely perceptible Champagne and mucilaginous drinks were given, and the enemas continued, but at longest intervals. 4 p. m., temp. 99.1/2; pulse 72. Vomiting has ceased, and but little nausea. Diuresis has continued, and she complain for the first time of pain in region of kidneys, paroxysmal in character, lasting but for a few moments at a time. – 16th, 10 a. m., temp. normal; pulse 80. Has rested well since evening before; diuresis diminished; no pain in region of the kidneys; cephalalgia and muscular soreness remaining. – 17th, 10 a. m., patient much improved; temp. normal, pulse 80. Has taken food in fluid form with relish. Muscular soreness diminished, and but slight cephalalgia, which remained for several days. Two day later she complained of a peculiar sensation at the roots of her teeth, and diarrhoea, which symptoms lasted but a short the roots of her teeth, and diarrhoea, which symptoms lasted but a short time. The patient gradually improved, the muscular soreness being last to disappear. (O’BRIEN, N. Y. Medorrhinum Record, Feb. 8th, 1879.)

Richard Hughes
Dr. Richard Hughes (1836-1902) was born in London, England. He received the title of M.R.C.S. (Eng.), in 1857 and L.R.C.P. (Edin.) in 1860. The title of M.D. was conferred upon him by the American College a few years later.

Hughes was a great writer and a scholar. He actively cooperated with Dr. T.F. Allen to compile his 'Encyclopedia' and rendered immeasurable aid to Dr. Dudgeon in translating Hahnemann's 'Materia Medica Pura' into English. In 1889 he was appointed an Editor of the 'British Homoeopathic Journal' and continued in that capacity until his demise. In 1876, Dr. Hughes was appointed as the Permanent Secretary of the Organization of the International Congress of Homoeopathy Physicians in Philadelphia. He also presided over the International Congress in London.
