The dung of wild doves was preferred to the excrement of the domestic pigeon; administered internally, generally mixed with the seed of the nasturtium, in all inveterate pains affecting sides, shoulders, skull, loins, kidneys, in vertigo, head-aches, etc. It was used just as frequently in cities as in rural communities (lib. xii. p. 302). Mouse-dung seems to have been extensively used in medical practice, although Galen ridicules the fact, and does not mention the purposes of its employment (lib. xii. p. 307). The dung of barn-yard fowl was used for the same purposes as dove-dung. Some people thought that the dung was more efficacious if dropped by a fowl that had been stuffed with mushrooms. Galen here takes occasion to remark that all animals must differ in the character of their excreta as they do in their food; the same animal, by a change of habitat, and consequent change of food, must cause a perceptible variation in the qualities of its excrement (lib. xii. p. 304). Galen flatly expresses his disbelief in the medicinal value of the excrement of the goose, stork, eagle, or hawk, although he admits that they were used internally by many practitioners of good standing, in difficulties of the respiratory organs; but he says these same authorities are wont to extol the merits, in the treatment of the same diseases, of such absurd remedies as night-owl’s blood, human urine, etc.—(Galen, lib. 12, p. 305.) Lucian, in his treatise upon remedies for the cure of gout (“tragopodagra”), makes mention in several places of excrementitious remedies,—as, for example, “dung of mountain-goat and man,” “And Bones, and Skin, and Fat, and Blood, and Dung, Marrow, Milk, Urine, to the fight are brought.” —(Edition of William Tooke, F. R. S., London, 1820, vol. i. p. 741.) SEXTUS PLACITUS. This author is supposed to have lived in the beginning of the fourth century after Christ. The edition of his work, “De Medicamentis ex Animalibus,” was printed in Lyons, in 1537. The pages are not numbered, and the citations are consequently by chapter. Goat-urine was given as a drink to dropsical patients (“De Capro”). This urine was also drunk by women to relieve suppression of the menses. For inflammation of the joints, goat-dung was dried and applied as a fine powder; for colic, a fomentation of hot goat-dung was applied to the abdomen; for serpent bites it was applied as a plaster, and also drunk in some convenient liquor. For tumors goat-dung was to be applied externally. For ear troubles goat-urine was applied as a lotion. “Ad aures nimus bene audientium, Apri lotium in nitro repositum tepefactum, auribus instillatur audire facit” (“De Apro”). For burns, whether by water or fire, burnt cow-dung was to be sprinkled on. “Ad combusturam sive ab aqua, sive ab igne factam, Taurinus fimus combustus et aspersus sanat” (“De Tauro”).
