Note 21 — Chapter I

Note 21.—On the Deenár and Dirhem. The standards of gold and silver coin, among the Arabs, were the deenár and the dirhem: therefore, in this work, I call the former "a piece of gold," and the latter "a piece of silver." Their values have varied considerably at different periods; but in the present work, we shall sufficiently approximate to the truth, if we understand the average value of the former to be about ten shillings or half a guinea; and that of the latter, about sixpence.
