Corrected proofs

Page proofs of the collection, lacking the preliminaries and running from page 7 to page 102. It is not explicitly stated that these are the collated proofs, although it seems likely. There are some minor corrections in black in Schmidt's hand. Other corrections have been made in blue; these are probably not in Brackenbury's hand, and may therefore have been made by a collator responsible for transferring the corrections made on Brackenbury's set. A page from Brackenbury's manuscript is inserted before pages 72-73, for use as copy when re-setting because three lines were omitted during initial typesetting. Stored with Brackenbury's original typescript title page and contents list.
