On the Dator Formarum

Excerpted from Kitaab ash-Shifa 3.14

And each of these elements has latitude in its quality; it can be more and less, since its natural or accidental quality may have been intensified or weakened, while retaining its form and species. Nevertheless, this intensification and weakening has terminating limits. Once those limits are transcended the complete disposition in matter for that form is lost and a complete disposition for another form disposes [that matter].

Original Latin

Et de usu materiae est, quando disponitur dispositione completa ad recipiendum formam, quod scilicet influatur illa forma super eam a datore formarum in materiebus et amovet alias. Et idcirco appropriantur materiae consimiles ut sint materiae diversarum forrmarum a datore formarum.
