 bsursolides, or bissursolides, that is,

seconde sursolides, or double sursolides. But I maie call them seconde squares of cubes, alludyng at the same name. Howbeit if I looke to their forme and nature, I shall be inforced to call thē, longe cubes of cubes, or longe cubike cubes.

And so by like reason, doe I cal the nexte nombers square cubes of cubes, or square cubike cubes: whiche other men doe cal zenzizenzizenzikes, that is squares of squared squares.

But other men for aide of woorke, in extraction of rootes, haue giuen theim soche names, as maie beste put menne in remembraunce of redy worke therein. Whiche names I will vse also hereafter, in my writynges, bicause I will not bee an aucthor of vnnedefull singularitie.

And so bothe of vs hauyng good reasons, for those names, naither maie contempne other, neither contende together.

And although the names that I doe giue, maie seme to some menne (whiche are scarse apte iudges,
