duced from equal terms multiplied equally into a greater term, such as 4 X4X9=144. But the spheniscoi, or little wedges are such as are multiplied by unequal numbers into unequal numbers. And cubes are produced from equal numbers equally through such as are equal. Those cubes however, which are of such a kind that the extremity of their depth terminates in the same number as that from which the side of the cubic quantity began, are denominated spherical; and such are the multiplications which pre ceed from the numbers 5 and 6. For 5)
BOOK Two 83 the principles of things, and who have given a twofold division to the nature of all beings,-these assert that the essences of all things consist of sameness and difference, the former of which is the cause of an immutable, and the latter of a variable mode of subsistence. These two principles likewise, pertain to the monad and the duad, the latter of which being the first number that departs from the monad, becomes on this account different. And because all odd numbers are formed according to the nature of the monad, and the numbers arising from the addition of these are squares, hence squares are said to be participants of sameness in a twofold respect, because they are formed from equality, each being produced by the multiplication of a number into itself, and both angles and sides being equal to each other, and because they are generated from the coacervation of odd numbers. But even numbers, because they are the forms of the binary number, and the aggregates of these form the numbers that are longer in the other pmt, are said, through the nature of the duad to depart from the nature of sameness, and to be participants of difference. Hence, since the sides of squares proceeding from equality tend to equality, the numbers that are longer in the other part, by the addition of unity depart from the equality of sides, and on this account are conjoined from sides that are dissimilar, and in a certain respect different from each other. Every thing incorporeal therefore, form its immutability participates of the nature of saneness, and every thing corporeal, from its mutable and variable essence, participates of the nature of difference, It must now therefore be shown, that all the species of numbers, and all habitudes, whether of relative discrete quantity, final number; but 6 in the multiplications by itself, has either 1, 3, 5, 7, or 9, preceding the final number, as is evident in the following numbers, 36, 216, 1296, 7776, 46656, 279936, 1679616, &c.
