(*ii*) Kaye admits that the figures are of the type of the period. His remark that they were in use much later is incorrect. The Tables III-V and XII show that the use of three horizontal bars to represent 3 is not found after the eighth century. The figure for 4 used in our grant plate is not found after the sixth century, and the same is true for the figure for 6. The forms of the numerical signs alone fix the date of the writing to the sixth century and not later.
