The very interesting Ur III text UET V, 796, that was treated by W. F. Leemans in 1960, was recently given fresh attention by M. Roaf, in an article which appeared in this same journal. The main problem raised by this text, which records a very large shipment of copper received at Dilmun, is the relationship between the weight standard of Dilmun and that of Ur: the former makes only use of minas, while the latter uses minas and talents. Already in Leeman's treatment of UET V, 796 it was established that the Dilmun mina weighed 2⅔ Ur minas. Collation of the text, provided by J. N. Postgate, allowed Roaf to suggest the restoration, in line 1, of the figure 13, ˹7˺  which perfectly fits the equivalence between 611 Ur talents 6⅔ Ur minas and the corresponding numbers of Dilmun minas (i.e. 13,750 minas).
Given this, it seems appropriate to attempt an evaluation of the absolute weights of the Dilmun and Ur units and to make some comment about (a) the articulation of the Dilmun system, (b) the possible relationship between this system and the others that were in use in various areas and periods of the ancient Near East.
