Definition of infrangible:
From king to king, from cardinal to cardinal, from the earliest in date of subject to the latest of his histories, we find the same thread running, the same link of honourable and righteous judgment, of equitable and careful equanimity, connecting and combining play with play in an unbroken and infrangible chain of evidence to the singleness of the poet's eye, the identity of the workman's hand, which could do justice and would do no more than justice, alike to Henry and to Wolsey, to Pandulph and to John.- "A Study of Shakespeare", Algernon Charles Swinburne.
Give me one of the best chemists who is sufficiently scientific to know how to mingle earth and ores, so that they will hold together firm and infrangible, and then let us see whether we have to fear the Spanish monarchy.- "Pictures of German Life in the XVth XVIth and XVIIth Centuries, Vol. II.", Gustav Freytag.
