Questio de aqua et terra (40)

(40) Nam cum adequatio corporis gravis non fiat per quantitatem, in quantum quantitas, sed per pondus, poterit ibi esse adequatio ponderis, cum non sit ibi adequatio quantitatis; et sic illa demonstratio est; apparens et non existens. (40) For, since the equalising of a heavy body is not effected by its quantity, as quantity, but by its weight, there might be an equalising of weight where there was no equalising of quantity; and so the demonstration is apparent and not real.
