In this curious book, full of learning and research, there are citations from more than three hundred authorities, some of them, of course, merely obscene and not coming within the purview of these notes, but others, as may be readily understood from reading the extracts taken from them, of the highest value in a scientific sense. Schurig gives an instance of voracity in which a certain glutton, after consuming all other food in sight, was wont to satisfy himself with urine and excrement: “Et si panes deerant, sua ipse excrementa comedebat et lotium bibebat.” (Schurig, “Chylologia,” Dresden, 1725, p. 52.) A case is given of a patient who having once experienced the beneficial effects of mouse-dung in some complaint, became a confirmed mouse-dung eater, and was in the habit of picking it up from the floor of his house before the servants could sweep it away.—(See Schurig, “Chylologia,” Dresden, 1725, p. 823 _et seq._) The enceinte wife of a farmer in the town of Hassfort, on the Main, ate the excrements of her husband, warm and smoking.—(See Christian Franz Paullini, “Dreck Apothek,” edition of Frankfort, 1696, page 8. See also quotation from “Ephemeridum Physico-Medicorum,” Leipsig. 1694, on page 212 of this volume.) “Chacun en fait, en voit, en sent, en touche, en parle, souvent en écrit, quelquefois en lit, et si chacun n’en mange pas, c’est que nous ne sommes pas encore au temps où les bécasses tomberont toutes rôties; mais de celui-là en voudrait manger.”—(Bibliotheca Scatalogica, p. 21, “Oratio pro Guano Humano.”) An extract is here given from a letter sent to Charlotte Elizabeth of Bavaria, Princess-Palatine, daughter of Charles Louis, Elector-Palatine of the Rhine, born at Heidelberg, in 1652; she married the brother of Louis XIV., the widower of Henrietta Maria of England. The letter in question was sent her by her aunt, the wife of the Elector of Hanover, and may serve to give an idea of the boldness of the opinions entertained by the ladies of high rank in that era, and the coarseness with which they expressed them:— “HANOVRE, 31 Octobre, 1694. “Si la viande fait la merde, il est vrai de dire que la merde fait la viande.... Est-ce que dans les tables les plus délicates, la merde n’y est pas servie en ragoûts?... Les boudins, les andouilles, les saucisses, ne sont-ce pas des ragoûts dans des sacs à merde?” The letters here spoken of are to be found almost complete in the Bibliotheca Scatalogica, pages 17-21.
