TBE "MOGUL" DIAMOND.

own private property, to be found, before his demise, in the possession of his undutiful son ? A satisfactory answer is supplied by a reference to the length of time required for cutting large Diamonds by the old process. The " Eegent," half the size of the " Mogul," required two years for the operation, although facilitated by recourse to cleavage : the " Mogul," therefore, which, besides being of a more elaborate pattern, was entirely ground away upon the wheel, cannot possibly be supposed to have occu­pied less than double that space of time for its cutting. Now Mirgimola took refuge at the Mogul's court in 1655, and before the end of the next year Shah Jehan (then upwards of seventy), having fallen dangerously ill, had been virtually deposed, and, as it were, imprisoned by his eldest son Darà, who thus sought to make sure of the succession. Aurungzeb took up arms against Darà, defeated him, and proclaimed himself emperor in August, 1658. Thus, almost immediately upon the great stone's being put into Borghis' hands, its rightful owner had lost all control over it : in fact, had he been able or permitted to superin­tend the operation, there can be no doubt his experience and taste in such matters would have brought about a ' widely different result/
There now remains to be considered a theory advanced by Prof. Maskelyne, and supported by very elaborate and ingenious calculations, but in which I, though most re­luctant to differ from so high an authority, cannot possibly acquiesce. Briefly stated it amounts to this, that the large Diamond exhibited to Tavernier was not Mirgimola's (which he never saw at all, it being still in the,; keeping of its second owner), but the Koh-i-noor itself, and that he " applied to the latter the story be, had heard about Borghis, and his mode of treating the other. To get over'the vast discrepancy between the weights of the two, it is sug-
