Howe Tables, Bordes, Glasse, or any such like are mea∣sured, accordinge to theyr length and breadth onely to the foote square. THE XI. CHAPTER. (Book 11)

THis thing is performed by y^e helpe of a large ta∣ble folowing, diuided in sixe smal tables, and as many margines The fyrst and left marigne be ginneth at .¼. whiche is one quarter of an ynch, and extendeth to .6. Inches, as ye may playnely perceyue yf ye runne downe by that margyne. This hath his Table on the ryghte syde adioy∣ninge vnto him. The other taketh his begyn∣ninge at .6. ynches .¼. and endeth at .12. hauyng his proper table also. The thyrde, from .12 ¼ to .18. And so from .18 ¼. to .24. From .24 ¼. to .30 The laste margine is from .30. 1/4 to .36, and there endeth.

Of this that is sayd, you may gather that euery margine hath his Table on his ryght syde. Also you muste knowe that in the top and beneth I haue put (as in the table of Tymber measure) these words, fote, ynche, and partes, to sygnify fete, ynches, and partes of an ynch. Whensoeuer ye lyste to measure, Borde, Glasse, or any other suche, with the breadth of it enter this Table: and seeke that breadth in his proper margine. There ye shall fynde in right order how many fete, ynches, or partes, of an Inche belonge to a foote square. So often as the measure is in your stuffe, iust as many fete haue ye in that borde or suche lyke. If the breadth excede this Table: than diuide y^e breadth in partes and worke as is and shall be declared. So the ingenious applyeth this Table for all maner breadthes moste exactly.

Ensample.

SƲypose I haue a pane of Glasse, or a borde, whose breadthe were 22. ynches .¼. the length .16. fote. In the fourth margin I finde this breadthe .22. and .¼. And euen with it in the Table rightward I se .6. ynches .⅓. So much of my ruler (wanting some small quantity) ma∣keth a foote. Nowe, because in the lengthe of my borde (whiche is 16. foote) that measure is founde .29. tymes, and .⅔. partes. I concluded .29. foote ther to be, & two thyrde partes of a foote square, accordinge to

that length and breadth. I sayde (wantinge some small quantitie) be∣cause of the poynte ioyned to this fraction ⅔. whiche is put to diminish that fraction some little thinge, as is declared playnely in the other tables before put forthe.

HE that desyreth to measure Chamber floores, Pauimentes, or such lyke: let him onely multiply the Breadth with y^e lengthe: so the producte sheweth the contente.

Ensample.

IF there were a Pauement. 100. foote long, and in Breadthe. 50. I must nedes conclude (by multiplicaciō of that lēgth in the breadth) there to be conteyned. 5000. foote.

Or thus without Arithmetike when the breadthe exceadeth the Table.

DIuide the breadthe in partes (as is opened in the declaration of the Table of accompt) and worke as I haue before instruc∣ted. So for Pauementes all maner wayes it serueth youre turne. Of this matter to put for the tables, were superfluous tediousnes and follye. The ingenious with these fewe, will be satisfyed.
