It is worthy of remark, that the ancients made ointments of this mineral alkali and oil, but not hard soap, though by these means they approached nearer to the invention than the old Germans in their use of wood-ashes; for dry solid soap can be made with more ease from the mineral than the vegetable alkali; and when Hungarian, French, and German soap are of equal goodness, the last does more credit to the manufacturers because they cannot employ the mineral alkali. I shall here observe, that this alkali was used for washing by the Hebrews, and that it occurs in the sacred writings under the name of borith251.

      The cheapest however, and the most common article used for washing, was the urine of men and animals. When this excrement becomes old, the alkali disengages itself, which may be perceived by its fœtid smell; and such alkalised urine being warmed, and employed to wash greasy clothes, produces the same effects as the nitrum of the ancients. It is still used for the like purpose in our cloth manufactories.

      To procure a supply of it, the ancient washers and scourers placed at the corners of the streets, vessels which they carried away after they had been filled by the passengers, who were at liberty to use them; and the practice of having such conveniences was certainly more decent than that of employing the walls of churches and other buildings, which the police of Dresden forbade some years ago, but with no effect. At Rome, that which at present spoils and renders filthy our noblest edifices, was converted to use. When clothes were washed, they were trod upon with the feet, as was the case in the cloth manufactories at Leeds, Halifax, and other places of England, where the urine was collected by servants, and sold by measure to the manufacturers under the name of old lant. On account of the disagreeable smell attending their employment, scourers at Rome were obliged to reside either in the suburbs or in some of the unfrequented streets252.

      My readers here will undoubtedly call to remembrance the source of taxation devised by the emperor Vespasian, who, as his historians tell us, urinæ vectigal commentus est253. It is not certainly known in what manner this impost was regulated. Did the emperor declare that article, which was not subterraneum rarius, to be a regale as a res derelicta, so that the scourers were obliged to pay him what he thought a reasonable sum proportioned to the benefit which they derived from it? Or was it imposed only as a poll-tax? For every tax upon anything indispensably necessary to all, is, to speak in the language of finance, the same as what is called a poll-tax, or a tax paid by every one who has a head. The latter conjecture is the most probable, especially as this tax continued two centuries, till the time of Anastasius, and as we read also of vectigal pro urina jumentorum et canum, which was exacted from every person who kept cattle. Vespasian therefore was not fortunate in the choice of a name for his tribute, which on that account must have been undoubtedly more detested. A poll-tax at present is called by those who do not speak favourably of it, the Turkish-tax, because the Turks impose it on all unbelievers. When it was introduced by Louis XIV. in 1695, he called it la capitation.

      Of plants with a saponaceous juice, the ancients, at any rate, used one instead of soap; but it is difficult or rather impossible to define it. I shall not therefore content myself merely with transcribing the passages where it is mentioned, but I shall arrange whatever I can find respecting it in such a manner, as, according to my opinion, the names of plants ought to be explained in dictionaries.

      Στρουθίον, Struthium, Latinis Herba lanaria, et Plinio etiam Radicula.

      1. Est planta spinosa, Theophrastus, Plinius.

      2. Grata aspectu, sed sine odore, Theophrastus, Plinius.

      3. Folio oleæ, Plinius; vel papaveris Heraclei, Theophrastus.

      4. Caule ferulaceo, tenui, lanuginoso, eduli, Plinius.

      5. Radice magna, acri, medicinali, Plinius, Dioscorides; spumescente, Lucian.

      6. Floret æstate, Theophrastus. Plinius; sed semen nullum, Plinius.

      7. Nascitur saxosis et asperis locis, Plinius.

      8. Sponte, præcipue in Asia Syriaque; trans Euphratem laudatissima; sativa ubique, Plinius.

      9. Radix conditur ad lanas lavandas, Theophrastus, Plinius, Dioscorides, Columella, et alii.

      10. Herba ovibus lac auget, Plinius.

      The above is all that the ancients have told us respecting this plant. The information is indeed very scanty, and at the same time it is not altogether certain; but even if it were, it would be sufficient only to confute some conjectures, but not to establish the systematic name of the plant. I call the properties of it described to us uncertain: first, because I do not know whether Pliny did not mean to distinguish the wild plant from that which was cultivated, and many have understood as alluding to the former that which I have applied to both: secondly, because the words of Theophrastus, being in one passage evidently corrupted, will admit of various constructions; and because in another, on account of some exceptions, of which he speaks, they appear at least to me unintelligible: thirdly, because Pliny, who gives us the best account of it, is the only author who calls the struthium or soap-plant radicula, a name by which is rather to be understood a dye-plant of the same kind as madder. We have reason therefore to suspect that he has confounded the properties of the two plants, especially as the fourth property was ascribed by others to a Rubia, Asperula, or Galium, which was cultivated in Syria, and named often radicula Syriaca. On the other hand, this diminutive is very ill-suited to a root which Pliny himself calls large.

      The words of that author, “tingenti, quicquid sit cum quo decoquatur,” have been by some explained as if he meant that the struthium was a dye-plant, though as a soapy plant it must have been destitute of colour; and they have hence deduced a proof that Pliny confounded the struthium with the radicula used in dyeing. On the other hand, Hardouin reads unguentis instead of tingenti. He assures us that he found the former in manuscripts, and is of opinion that the sap of the struthium was used also for ointments.

      In my opinion, however, tingenti must be retained; and the meaning is that when cloth was to be dyed it was necessary to prepare it for that purpose by soaking it and washing it with the sap of this plant. This he expressly tells us himself; “tingentibus et radicula lanas præparat.” It is probable that the ancient dyers mixed their dye-liquors with the juice of the struthium, for the same purpose as bran and the seeds of fenugreek are added to dye-liquors at present; that is, to render them thicker and more slimy, in order that the colouring particles may be longer and more equally suspended in or diffused through them254. The words quidquid sit cum quo decoquatur will now become intelligible. Whatever may be employed for dyeing, says the author, the addition of the juice of the struthium is serviceable.

      As what has been said contains nothing that can enable us to determine the genus of the struthium according to the rules of botany, we may be allowed to conjecture that it was one of those plants still used for the like purpose in Italy and other neighbouring countries. Fuchs thinks it must have been the Saponaria officinalis (soap-wort), the roots of which indeed contain a saponaceous juice that readily changes the saliva into froth. The root was employed for that purpose by the impostor in Lucian; and the juice is used at present for cleaning wool and cloth. In the Helvetian Alps, the sheep, before they are shorn, are washed with a decoction of the plant and its roots; and with a mixture of ashes it serves for cleaning linen. The taste of it is so sharp, that it is compared by some to that of the small burnet-saxifrage.
