Itaque quemadmodum sol per siderum spatia vadens dilatat contrahitque dies et horas, sic bulla in horologiis ingrediens per puncta contra centri tympani versationem, cotidie cum transfertur aliis temporibus per latiora, aliis per angustiora spatia, menstruis finitionibus imagines efficit horarum et dierum. De administratione autem aquae, quemadmodum se temperet ad rationem, sic erit faciendum.
