Sal ammoniac derives its name from having been first made in the vicinity of the temple of Jupiter Ammon; it would be of consequence to us to know whether or not the priests of that temple had administered urine in disease before they learned how to extract from it the medicinal salt which has come down to our own times.
Schurig devotes a chapter to the medicinal preparations made from human ordure. In every case the ordure had to be that of a youth from twenty-five to thirty years old. This manner of preparing chemicals from the human excreta, including phosphorus from urine, was carried to such a pitch that some philosophers believed the philosopher’s stone was to be found by mixing the salts obtained from human urine with those obtained from human excrement.—(See “Chylologia,” pp. 739-742.)
The method of obtaining sal ammoniac was not known to Pliny; he knew of gum ammoniac, which he says distilled from a tree, called metopia, growing in the sands near the Temple of Jupiter Ammon, in Ethiopia.—(Nat. Hist. lib. 12, cap. 22.)
“A notion has prevailed that sal ammoniac was made of the sand on which camels had staled, and that a great number going to the temple of Jupiter Ammon gave occasion for the name of ammoniac, corrupted to armoniac. Whether it ever could be made by taking up the sand and preparing it with fire, as they do the dung at present, those who are best acquainted with the nature of these things will be best able to judge. I was informed that it was made of the soot which is caused by burning the dung of cows and other animals. The hotter it is the better it produces; and for that reason the dung of pigeons is the best; that of camels is also much esteemed.” (Here follows a description of the method of distilling this soot.)—(Pocock’s “Travels in Egypt,” in Pinkerton, vol. xv. p. 381.)
“Purifiée, l’Urine sert dans les arts pour dégraisser les laines, dissoudre l’indigo, prépare le sel ammoniac.”—(Personal letter from Prof. Frank Rede Fowke, South Kensington Museum, June 18, 1888.)
MANURE EMPLOYED AS FUEL.
The employment of manures as fuel for firing pottery among Moquis, Zuñis, and other Pueblos, and for general heating in Thibet, has been pointed out by the author in a former work. (“Snake Dance of the Moquis,” London, 1884.) It was used for the same purpose in Africa, according to Mungo Park. (“Travels,” etc., p. 119.) The dung of the buffalo served the same purpose in the domestic economy of the Plains Indians. Camel dung is the fuel of the Bedouins; that of men and animals alike was saved and dried by the Syrians, Arabians, Egyptians, and people of West of England for fuel. Egyptians heated their lime-kilns with it.—(McClintock and Strong, “Dung.” See, also, Kitto’s Biblical Encyclopædia, article “Dung.”)
Pocock says of camel dung: “In order to make fuel of it, they mix it, if I mistake not, with chopped straw, and, I think, sometimes with earth, and make it into cakes and dry it; and it is burnt by the common people in Egypt; for the wood they burn at Cairo is very dear, as it is brought from Asia Minor.”—(Pocock, in Pinkerton, vol. xv. p. 381.)
Bruce does not allude to any of the filthy customs which are detailed by Schweinfurth, Sir Samuel Baker, and others; he does say that the Nuba of the villages called Daher, at the head of the White Nile, Abyssinia, “never eat their meat raw as in Abyssinia; but with the stalk of the dura or millet and the dung of camels they make ovens under ground, in which they roast their hogs whole, in a very cleanly and not disagreeable manner.”—(“Nile,” Dublin, 1791, vol. v. p. 172.)
“Argol, the dried dung of camels, is the common fuel of Mongolia.”—(“Among the Mongols,” Rev. James Gilmour, London, 1883, pp. 84, 146, 191, 296.)
