For the structure of the last example in the box, compare Mary liked[Jane paying it to herself]. Herself, especially if not emphasized, will again be linked, within the brackets, to Jane. Now in the passage from Powell, himself is compatible, in similar brackets, with an American biographer of X. Trapnel. Yet that is not its antecedent. Instead it has to be understood with Bagshaw, which is again outside this unit. Why, in that case,did Powell not write him? One reason, perhaps, is that it might be taken to refer to Trapnal, even though by this stage in the story he is dead.
