uti explicentur, non putavi ante ponendum, nisi prius de materiae copiis, e quibus conlatis aedificia structuris et materiae rationibus perficiuntur, quas habeant in usu virtutes, exposuissem, quibusque rerum naturae principiis essent temperata, dixissem.

Afterwards I shall expound what virtues they have when employed, and I shall declare of what natural elements they are blended.
