The present structure connected with the well was renovated in 1851. It was built in 1670 to replace an earlier one, repaired by George Jamieson, the artist, but soon afterwards completely demolished by the overflowing of the adjoining Denburn. The present building, according to Mr. A. Jervise, in the fourth volume of the "Proceedings of the Society of Antiquaries of Scotland," "bears representations of the Scottish Thistle, the Rose of England, and the Fleur-de-lis of France, surmounting this inscription:-- 'As heaven gives me So give I thee.' Below these words is a carving of the rising sun, and the following altered quotation from Horace:-- 'Hoc fonte derivata Salus In patriam populumque fluat.' "It appears," continues Mr. Jervise, "that the virtues of this Spa were early known and appreciated, for in 1615 record says that there was 'a long wyde stone which conveyed the waters from the spring, with the portraicture of six Apostles hewen upon either side thereof.' It is described as having then been 'verie old and worne.'" An unusual kind of holy well, viz., one, in which salt water takes the place of fresh, is to be found in the case of the Chapel Wells in Kirkmaiden parish, Wigtownshire, half way between the bays of Portankill and East Tarbet. About thirty yards to the north-west are the ruins of St. Medan's Chapel, partly artificial and partly natural, a cave forming the inner portion. In days gone by, the spot was much frequented on the first Sunday of May (O.S.), called Co' Sunday, after this cave or cove. Dr. Robert Trotter, who examined the chapel and the wells in 1870, gives the results of the observations in the eighth volume of the "Proceedings of the Society of Antiquaries of Scotland" (new series). He says, "These wells--three natural cavities in a mass of porphyritic trap--are within the tide mark, and are filled by the sea at high water of ordinary tides. The largest is circular, five feet in diameter at the top, and four feet at one side, shelving down to five feet at the other, and is wider inside than at the top, something like a kailpot in fact, and it is so close to the edge of the rock that at one place its side is not two inches thick. The other wells almost touch it, and are about one foot six inches wide and deep respectively." Sickly children were brought to be bathed, the time selected being just before sunrise. Dr. Trotter mentions that children are still brought occasionally, sometimes from long distances. The ceremony described to him by an eyewitness was as follows:--"The child was stripped naked, and taken by the spaul--that is, by one of the legs--and plunged headforemost into the big well till completely submerged; it was then pulled out, and the part held on by was dipped in the middle well, and then the whole body was finished by washing the eyes in the smallest one, altogether very like the Achilles and Styx business, only much more thorough. An offering was
