A fly-sheet, undated, which may be found in the British Museum, sets forth the plan of Gerbier's Academy. He addresses himself 'to all Fathers of Noble Families and Lovers of Vertue,' desires public notice of his great labours and exertions, and informs the world that 'the chiefe Famous Forraigne Languages, Sciences, and Noble Exercises' are taught in his establishment. 'All Lovers of Vertue,' of what age soever, are received and instructed, and each of them may select such studies, exercises, and sciences as are most consonant to his genius. Public lectures are announced to be read gratis every Wednesday afternoon, in the summer at three, in the winter at two o'clock. A competent number of children of 'decayed families' are taught without fee. 'Lovers of Vertue' are stated to be thus freed from the dangers and inconveniences incident to travellers, who repair to foreign parts to improve themselves, and leave the honour of their education to strangers, running 'the hazzard of being shaken in the fundamental points of their religion, and their innate loyalty to their native country.' The nation is therefore exhorted to reflect seriously on Sir Balthazar's proffers; to embrace them vigorously and constantly to countenance and promote them, 'since that the languages declared to be taught in the Academy are:--Hebrew, Greek, Latin, French, Italian, Spanish, High Dutch, and Low Dutch, both Ancient and Modern Histories, jointly with the Constitutions and Governments of the most famous Empires and Dominions in the World, the true Natural and Experimental Philosophy, the Mathematicks, Arithmetic and the Keeping of Bookes of Accounts by Debitor and Creditor, all Excellent Handwriting, Geometry, Cosmography, Geography, Perspective, Architecture, Secret Motions of Scenes, Fortifications, the Besieging and Defending of Places, Fireworks, Marches of Armies, Ordering of Battailes, Fencing, Vaulting, Riding the Great Horse, Music, Playing on all sorts of Instruments, Dancing, Drawing, Painting, Limning, and Carving,' etc. Certainly Sir Balthazar's was a sufficient catalogue of arts, sciences, and accomplishments. The lectures 'composed for the good of the public' were afterwards printed, and to be obtained at Robert Ibbitson's house in Smithfield, near Hosier Lane. It may be noted that a lecture upon the art of well-speaking, brought upon the lecturer the derision of Butler, author of _Hudibras_.
