The reader probably knows what ringworm is--a fungoid eruption on the skin, not uncommon in the spring and early summer in children and young people of plethoric habits. There is a very wide-spread belief over the West Highlands and in the Hebrides that ringworm can be readily cured by rubbing it over and around once or twice with a gold-ring--a woman's marriage ring, if it can be had, being always preferred. In our younger days we recollect seeing the cure applied on more than one occasion, whether with the desired result, or ineffectually, we do not know--we probably little thought in those days of kilts, cammanachd, and barley bannocks, of inquiring. For many years we had neither seen nor heard anything either of the disease or of its popular cure, until, by the merest accident, it came under our notice a few days ago. Riding home one evening last week, we observed two little girls and a sturdy long-legged haflin lad sitting patiently in front of a cottage, the door of which was shut and locked. The youngsters, rather better dressed than usual, had come from a considerable distance, and we wondered what they could be doing there. On mentioning the matter next day, we had the story in full as follows:--The three were suffering from ringworm. The owner of the cottage has a marriage ring of wonderful efficacy in curing this epidermic distemper. They had come from one of the inland glens to be operated upon, but the possessor of the ring was away in Glasgow, and only returned home by steamer late that evening. When she did arrive, the young people were duly manipulated and ring-rubbed secundum artem; and in four and twenty hours thereafter we were gravely assured they were quite healed. Any gold ring is usually employed, but the particular ring referred to in this case is much sought after on such occasions, because, as our informant said, it is of "guinea gold," by which we suppose very pure gold, with the least possible alloy, is meant; and because it is the property of a widow who was married to one husband more than fifty years. A belief in the virtue of gold rings in cures of ringworm is, as we have said, very wide-spread and honestly held by many. Whether, in common phrase, there is "anything in it," or the whole affair is sheer nonsense, we shall not take it upon us to decide. We merely submit a common and curious article of popular belief for the consideration of our grave and learned dermatologists and the faculty at large. One thing is certain,--the owner of the marvellous ring makes no vulgar profit by her frequent use of it in such cases. She is in comfortable circumstances, and the whole affair, as far as she is concerned, is a mere labour of love.
