<P> Pattertwig and Aunt Gertrude do not appear in the final version of the novel . Pattertwig does, however, appear as a Narnian creature in Prince Caspian, and Aunt Gertrude is the principal of the experimental school in The Silver Chair . </P> <P> Some doubt has been cast on the authenticity of the Lefay Fragment, as the handwriting in the manuscript differs in some ways from Lewis' usual style, and the writing is not of a similar calibre to his other work . Also in August 1963 Lewis had given instructions to Douglas Gresham to destroy all his unfinished or incomplete fragments of manuscript when his rooms at Magdalene College, Cambridge were being cleaned out, following his resignation from the college early in the month . </P> <P> A number of aspects of The Magician's Nephew parallel Lewis' own life . Both Digory and Lewis were children in the early 1900s, both wanted a pony, and both were faced with the death of their mothers in childhood . Digory is separated from his father, who is in India, and misses him . Lewis was schooled in England after his mother's death, while his father remained in Ireland . He also had a brother in India . Lewis was a voracious reader when a child, Digory is also, and both are better with books than with numbers . Digory (and Polly) struggle with sums when trying to work out how far they must travel along the attic space to explore an abandoned house, Lewis failed the maths entrance exam for Oxford University . Lewis remembered rainy summer days from his youth and Digory is faced with the same woe in the novel . Additionally Digory becomes a professor when he grows up, who takes in evacuated children during World War II . </P> <P> The character of Andrew Ketterley also closely resembles Robert Capron, a schoolmaster at Wynyard School, which Lewis attended with his brother, whom Lewis suggested during his teens would make a good model for a villain in a future story . Ketterley resembles Capron in his age, appearance, and behaviour . </P>
