Attention is called to a substantial number of loose manuscript pages of an intended Practical Grammar and Reader of Illyrian for use of foreigners with a knowledge of Italian. This survives in England in the archive of Frederick North, Fifth Earl of Guilford (1766-1827). Quotations from the text and a description of this Grammar are given and some biographical information about North, a polyglot philhellene. He visited Dubrovnik on several occasions, knew F.-M. Appendini and the Dubrovnik "latinisti" and learned Illyrian. The Grammar was intended for use in the University of Corfu, of which Guilford became the first Chancellor on its foundation in 1824, but was never published.
