Unpublished letter, regarding method of teaching consonants from Mary Warden to [Sir Joseph Banks] In this covering letter, Warden describes the provenance of her method of teaching the consonants of the English language. She explains that her father-in-law invented the method and passed it on to her husband, who improved on the method but disappeared in a bout of alcoholism. She therefore wishes to present the method herself to the Royal Society. Subject: Linguistics / Education Written by Warden at No 11 Arabella Row [now Lower Grosvenor Place], Pimlico [London].
