The following from the pen of Dr. C. C. Huff, of Huron, D. T., from vol. i, of the Minn. Medical Monthly, No. 9, illustrates the use of one of these remedies in neuralgia:

"Schussler describes Magnesia phos. as the earthly constituent of muscles and nerves. Dalton says the salts of magnesium have been found to be in larger quantity than those of lime in the muscles. Grant this fact, then, and we have Magnesia phos, acting as a nerve remedy, and any disturbance of the system causing a molecular change in the nutritive elements of this salt would produce the characteristic pains of this remedy. They are described as being of a shooting character, like lightning, drawing and tearing, inclined to move from place to place; they, moreover, assume a periodicity of recurrence, not, however, having any regard for regularity. We likewise find these pains in headache, generally frontal, in faceache, neuralgia of the stomach and bowels, of the ovaries and often in the limbs. Stomach-pains frequently radiate from the umbilicus, and are relieved by pressure (resembling in this respect Coloc, Aloes, Caustic,, Nux vom,, Iris vers, and Sulphur) and warmth, especially dry heat, best applied by means of an inverted hot plate, lined with flannel. In England the farmers use the remedy with prompt results for flatulent colic in horses.

The following is my experience with the remedy, and all my results have been from 12z trituration:

"Case I. Miss S., aet. 24, dart complexion, nervous temperament, clerk. She had been under treatment for facial neuralgia for two weeks previous, the principal remedy being morphia, without relief. On being called to the case, I found the patient much prostrated, the right side of the face and supraorbital region somewhat swollen, pains very severe, of a crampy, shooting, darling nature. There was also much tenderness over the affected side. The pains were of an intermittent character, and seemed to affect different parts of the head and face on different days. Magnesia phos. cured this case in twelve hours.

"Case 2. Miss B., let. 12, dark complexion, nervous temperament, slight build, has neuralgia, from exposure to a strong north wind, and was under the so-tailed 'regular' treatment for three days before I was called, and had taken massive doses of Bromide 0/potash and Chloral hydrate, with no relief. I found her in bed, almost frantic with pain, flushed face, eyes injected, with a high degree of photophobia; pain was left-sided and involved the supraniaxillary portion of the trigeminus, In character the pain was lancinating, crampy, darting and shooting, frequently extorting cries. Magnesia phos. was given and resulted in a speedy recovery.

"Case 3. Miss S., aet. 20, brunette, tall and slender, nervo.bilious temperament, occupation topographer. She was taken suddenly with acute pain in right side of the face, the pain involving the supra- and infraorbital region, paroxysmal, of a darling, tearing character. Magnesia phos. cured promptly.

"The above cases have been taken from my note-book and are illustrative of the action of this remedy in neuralgia of the fifth nerve and its branches I have also cured one case of neuralgia of the stomach where the characteristic pains were present. 1 have relieved colic in young children with the same remedy when Chamom., Nux vom, and Coloc. had failed".

Case of prosopalgia of several weeks' standing, relieved by warm cotton and aggravated by cold. Magnesia phos. 12x cured in three weeks. - Allg. Horn. Zest., vol. S8, p. 46.

Dr. H. C. Allen reports a case of right facial neuralgia with sharp, quick, spasmodic, lightning-like pains, sensitive to touch, relieved by heat and pressure, accompanied by prostration and night-sweats, cured by Magnesia phos.300 after several other remedies had failed to give permanent relief.

Also, another case cured by the same remedy and potency where the pains were intermittent, darting, lightning-like, suddenly appearing and disappearing, relieved by heat and pressure; at the same time an annoying constipation disappeared.

Prompt curative action of Magnesia phos. by Dr. Goullon: "On April 13th a patient wrote me that for nine days she had been in bed without medical help, suffering from a maddening pain. Through catching cold she got a severe trouble in the ear and then a prosopalgia on the left side, affecting the lower maxillary bone, also the frontal, and involving the whole left side of the head, back to the nape of the neck. She went to an apothecary for Bryon., but he advised Bet/ad., which didn't help. Deep within the ear an abscess developed, which broke two days ago, discharging pus and now water, which is quite irritating, for it has produced an eruption wherever it touched. The ear still pains; the prosopalgia remains as before. The pain is maddening, and there is high fever with sleeplessness; she doesn't sleep at night and only one or two hours in the day. She perspires freely, which is unusual with her. Yesterday she had a severe pain in the right hip, resulting from a bath, I was unable to see the patient, as she, at that time, lived at Leipsic, and yet she needed help at once. What should I give her? Siticca? The nightly aggravation would suit this remedy, but the abscess in the ear was gone, yet the facial pain remained.

Spigel.? There were indications for it. - she bad a tendeticy to heart trouble. She had formerly bad pains in the articulations of the hand, in the arm and side, most severe at the heart. She described it as if the heart would be twisted out, with a throbbing as if something were unwound. Perhaps it was a rheumatism, located in the face, but even here Spigel. would be called for. Then there is Arnica, which has lately been extolled as a specific. Further, I had some reliance on Stannum, which had cured for me many neuralgias that even the great nerve remedy. Quinine, had left untouched. The embarrass de richesse still increased. Chamom. ought to be given for the unbearable pain. Again there was Mercur. on account of the tendency to sweating, and Arsenic, on account of sleeplessness.
