Les principes infallibles et les règles asurées de la juste prononciation de nôtre langue [microforme]
A 1670 French treatise on correct pronunciation of the French language, written by A. Lartigaut and published in Paris by J. d'Houry. Its two decorative tailpieces show a dense black-ink engraved strip, one with winged putti and scrollwork, the other with a bird among leafy foliage, suggesting ornamental bands for dividing text or closing sections.
