Note 71 — XLI. ORDURE AND URINE IN MEDICINE.

“We have in the folk-medicine, which still exists, the unwritten record of the beginning of the practice of medicine and surgery.... The early history of medical science, as of all other developments of culture, can be studied more narrowly and more accurately in the folk-lore of this and other countries than some students of modern science and exact modern records may think possible.”—(“Folk-Medicine,” William George Black, London, 1883, pp. 2, 3.)
