A curious application of homoeopathic magic to the {p83} cure of disease is founded on the old English superstition that if a shrew-mouse runs over a beast, be it horse, cow, or sheep, the animal suffers cruelly and may lose the use of its limb. Against this accident the farmer used to keep a shrew-ash at hand as a remedy. A shrew-ash was prepared thus. A deep hole was bored in the tree, and a shrew-mouse was thrust in alive and plugged in, probably with some incantations which have been forgotten.​[284] An ancient Indian cure for a scanty crop of hair was to pour a solution of certain plants over the head of the patient; this had to be done by a doctor who was dressed in black and had eaten black food, and the ceremony must be performed in the early morning, while the stars were fading in the sky, and before the black crows had risen cawing from their nests.​[285] The exact virtue of these plants has escaped our knowledge, but we can hardly doubt that they were dark and hairy; while the black clothes of the doctor, his black food, and the swarthy hue of the crows unquestionably combined to produce a crop of black hair on the patient’s head. A more disagreeable means of attaining the same end is adopted by some of the tribes of Central Australia. To promote the growth of a boy’s hair a man with flowing locks bites the youth’s scalp as hard as he can, being urged thereto by his friends, who sit round watching him at his task, while the sufferer howls aloud with pain.​[286] Clearly, on the principle of capillary attraction, if I may say so, he thus imparts of his own mature abundance to the scarcity of his youthful friend.
