The wonderful therapeutic virtues of a Scotch lake named Loch-mo-naire are explained by a local legend as having arisen from certain magic crystals which had been cast into its waters. These crystals, if placed in water, rendered the liquid a potion of great curative power. They were the property of a woman who had gained by their possession a great reputation as a healer, but her success attracted the envy of a neighbor who determined to secure for himself the woman’s wonder-working stones. In pursuance of this design he came to her, feigning illness. She saw through his deception and sought safety in flight, but he pursued her and was gaining rapidly on her, when she threw the stones into the waters of the lake, crying out the Gaelic word _noire_, “shame,” and uttering the wish that its waters should be rendered powerful to cure the sick, all except those of the clan Gordon to which the would-be thief belonged. As the correct translation of the name of the lake is said to be not “Lake of Shame” but “Serpent Lake,” the legend appears to have no good foundation, but is perhaps as true as any of the popular tales purporting to explain the origin of the virtues of healing springs or waters.[316] To many stones was attributed the power of transmitting a certain remedial virtue to water or other liquid in which they were immersed. This, as we have related, was the case with the white stone that St. Columba sent to King Brude at Inverness when the king’s druid priest Broichan was suffering from disease. A peculiarity of this stone was that if it were required in the case of a person about to die, it would disappear from view. Thus its remedial powers could never be put to test unless success were assured.[317] There can be no reasonable doubt that some remarkable cures have been effected by means of relics, or by drinking the waters of a spring believed to have been pointed out by some divine vision. From a purely scientific standpoint this can be explained as the result of an extraordinary stimulation of the nerve-centres, caused by the rapt enthusiasm of religious faith. The relics, or the pure water, simply serve as an object about which this faith crystallizes, so to speak, and gains a concrete and external form, which in turn reacts upon the mind of the believer. It is a well-known fact that a great shock, or imminent peril, has sometimes suddenly restored the power of motion to those who have long been paralyzed. This view does not, however, necessarily exclude a religious interpretation of these phenomena when they are produced by religious impressions, for the divine will manifests itself by natural means, and a true understanding of the regular and normal working of these means should give us a deeper, truer, and purer faith.
