Igitur levi raraque cum sit proprietate, nec patiantur penetrare in corpus umidam potestatem, quocumque pondere fuerit, cogitur ab rerum natura, quemadmodum pumex, uti ab aqua sustineatur, sic autem magnas habent utilitates, quod neque in aedificationibus sunt onerosi et cum ducuntur a tempestatibus non dissolvuntur.
Therefore since these bricks are of a light and open property, and do not allow the humid potency to penetrate into the body, of whatever weight the body shall be, it is compelled by Nature to be upheld by water like pumice-stone. So indeed they have great advantages because they are not heavy in buildings, and when they are being made, they are not dissolved by storms.
