Ferrum Magneticum.

Sesquioxide of Iron. Loadstone. A black oxide of iron. FeO Fe2 O3.

Clinical.-Amaurosis. Diarrhoea. Flatulence. Ganglion. Rheumatism. Vision, disorders of. Warts. Whitlow.

Characteristics.-Caspari is the authority for Fer. magnet. It produces paralytic weaknesses like the other Iron preparations, of which this is the most peculiar: "After perspiring during a moderate walk, weakness and lassitude, which seem to proceed from the abdomen." As with Ferrum, there is < during a meal; flatulency, grumblings, movements in abdomen; with urgent diarrhoea after a meal. The abdominal sufferings are felt more on the left side. Very abundant and frequent emission of fetid wind. Many rectal and urinary symptoms are recorded. The appearance of warts may indicate that Fer. magn. is related to the sycotic constitution.

Teste, who puts Fer. magn. in the Arnica group along with Ledum, Croton, Rhus and Spig., has had some experience with it. It relieved (after Spig.) an old man suffering from chronic rheumatism of the nape of the neck, with irritable disposition. Also a case of compound capsular cataract in a gouty patient. A third patient had rheumatism of both thighs, coming on after violent exercise. This patient was treated in two attacks. In the first attack he received Arn. first, and then Fe. mag. In the second, Fe. mag. was given at once and the effect was speedy and marked. The fourth patient had a very unpleasant experience with the medicine. He suffered from a mercurial neurosis, and was very sensitive to medicines. One of the symptoms which led to its being given was a painful contraction of the posterior cervical muscles, against which no remedy Teste had tried had produced any effect. Fe. mag., four globules in a tumbler of water, two tablespoonfuls every day, was the prescription. The first tablespoonful, which was taken in the morning, seemed to produce a sensible improvement; but a quarter of an hour after the second dose, which was taken at 4 p.m., the sight became dim; a halo of fire, red and violet, was seen first in front of the right, and afterwards in front of the left eye; soon after, this halo, which formed a circular zigzag-shaped line, became narrower and narrower and finally produced such a complete blindness, that the patient assured Teste he was unable to distinguish night from daylight. This lasted one hour and did not pass off entirely till after a meal. Much more distressing phenomena followed: Towards 8 p.m. the pain in the nape, which first was seated on the left side, passed to the right, invading the whole extent of the trapezoid muscle, where it became literally frightful. "For two days and nights the patient, who was a brave and strong man, and whom I had seen bear the most painful surgical operations without uttering a sound, suffered to such an extent that he uttered heartrending cries." Camph., Puls., and Bry. failed to relieve, the first rather aggravated. Rhus t. effected some relief. But it did not prevent the recurrence, for eight days in succession, of the visual phenomena, though with less intensity than the first time, at irregular intervals, generally 6 or 7 a.m., and sometimes even at night in perfect darkness.
