Dupaix, Antiquités Mexicaines, Paris, 1834, Vol. II., Planche 26, fig. 75, and text in Vol. I., page 21, No. 75. Footnote 23: With our first glance at the picture of _Tepozcolula_ we were induced to believe that we had found therein a representation of the instrument which Petrus Martyr called a “_dolabra_,” and Sahagun “_azuela_.” The translation of the one is, pick or hoe, and of the other, cooper’s adze. Both of these, therefore, would have been instruments in which the blade and its edge are at right angles to their handle, and the management of which requires both hands of the workman. This supposition is refuted by the picture of the carpenter (cut 10), who is distinctly seen to hold the piece of wood in the left and the tool in his right hand. Footnote 24: Dupaix, l. c., Vol. II., Planche 26, fig. 74, and text Vol. I., page 21. Footnote 25: Torquemada, Mon. Ind., Lib.—, Chap.—: “They also used certain copper coins, almost in the shape of a Greek Tau, Τ, its width about three or four fingers. It was a thin piece of plate of an uncertain size, and contained much gold.” Clavigero, The History of Mexico, Ed. Ch. Cullen, London, 1807, Vol. VII., Sect. 36, page 386, evidently copies the sentence when he says: “Their fourth species of money, which most resembled coined money, was made of pieces of copper, in the form of a T, and was employed in purchases of little value.” THE KATUNES OF MAYA HISTORY. BY PHILIPP J. J. VALENTINI, PH.D. [_Translated from the German, by Stephen Salisbury, Jr._] [From Proceedings of American Antiquarian Society, October 21, 1879.] NOTE BY THE COMMITTEE OF PUBLICATION. The Publishing Committee are glad of the opportunity to print another paper from the pen of Professor Valentini. His previous contributions have been favorably received by some of the most competent judges. He is always ingenious and suggestive, taking care to sustain his views by adequate collateral information, and leaving an impression of earnestness and thoroughness, even though the reader should not be able always to see the way through his bold inferences to the important conclusions deduced from them. It seems apparent that new phases of opinion respecting the position in the world’s history held by the races occupying the central portions of the American Continent may be looked for in the near future. Or rather, perhaps, it may be claimed that vestiges of ancient and independent culture, of revolutions, conquests, and changing dynasties, extending back to a remote period of time, which have hitherto simply excited and bewildered travellers and explorers, bid fair to be subjected to tests and comparisons derived from wider and closer observation, for which the means are accumulating, and from which definite results are anticipated.
