It is rather interesting that Iolo Morganwg saw a stone of this kind in the year 1802, in the neighbourhood of Bridell, North Pembrokeshire. The following extracts from Iolo's Diary appeared in "Young Wales," June, 1901:--"Leave Cardigan, take the road to Llanfernach. Bridell Church.... Meet a man who carries a stone about the country, which he calls Llysfaen. Scrapes it into powder with a knife, and sells it at about five shillings an ounce as an infallible remedy for the canine madness. He says that this stone is only to be found on the mountains after a thunderstorm, that every eye cannot see it. He showed me the stone, and when I assured him and a little crowd that had gathered about him, that the stone was only a piece of the Glamorgan alabaster, the poor fellow was confounded and seemed very angry; but I was surprised to hear many positively assert that they had actually seen the Hydrophobia cured in dogs and man with this powder given in milk, and used as the only liquid to be taken nine days, and the only food also.... The name by which this fellow named his stone is obviously a corruption of Cleisfaen, from its blushy white colour, veined or spotted with a livid or blackish blue colour like that of a bruise (clais)." The excellent old Welsh Magazine "Y Gwyliedydd" for the year 1824, page 343, gives an account of two other such stones, one of them preserved at Maes y Ffynon, Maelienydd, and the other at Llwyn Madog, Breconshire. How these two stones were discovered the following story is given:--A man attacked with hydrophobia wandered away one day and slept on a hill, where he dreamt that a remedy for his disease was to be found in the ground under his head, where he was sleeping. After digging the ground, two white stones were discovered. A healing stone supposed to have descended from the sky was discovered on a farm called Disgwylfa, in Carmarthenshire. THE PHYSICIANS OF MYDDFAI. The following extracts from the book of remedies of The Physicians of Myddfai, will not be irrelevant, as those celebrated Physicians were of Fairy origin, having been furnished with medical prescriptions by their supernatural mother, the Fairy lady of Llyn y Fan, in Carmarthenshire. TO EXTRACT A TOOTH WITHOUT PAIN. "Take some newts, by some called lizards, and those nasty beetles which are found in ferns during summer time, calcine them in an iron pot and make a powder thereof. Wet the forefinger of the right hand, insert it in the powder, and apply it to the tooth frequently, refraining from spitting it off, when the tooth will fall away without pain. It is proven."--Physicians of Myddfai. FOR THE BITE OF A MAD DOG. "Seek some plantain, and a handful of sheep's sorrel, then pound well in a mortar with the white of eggs, honey, and old lard, make it into an ointment and apply to the bitten part, so that it may be cured."--Physicians of Myddfai. FOR PAIN IN THE EYE.
