Utraque autem ex minutissimis sunt instruenda, uti materia ex calce et harena crebriter parietes satiati diutius contineantur. molli enim et rara potestate cum sint, exsiccant sugendo e materia sucum; cum autem superarit et abundarit copia calcis et harenae, paries plus habens umoris non cito fiet evanidus, sed ab his continetur. simul autem umida potestas e materia per caementorum raritatem fuerit exsucta calxque ab harena discedat et dissolvatur, item caementa non possunt cum his cohaerere, sed in vetustatem parietes efficiunt ruinosos.
