Xeroxes (see Admin. History below). The arrangement of the xeroxes, carried out by P.D.A. Harvey, is exactly the same as that of the original papers which were in Darlington's study when he died. It is by a sequence of numbered files of papers, corresponding to the sequence of 'bundles' found in Darlington's study. Serial numbers for each xerox page were stamped on the back. A typewritten label was stuck onto each file, giving the file number and the range of the serial numbers contained in that file. All this information has been reproduced for each file in the following list, as well as Darlington's chapter numbers and titles where they appear. The individual file units represent groups of papers found in various places in Darlington's study. Offprints (often annotated by Darlington) are sometimes found with the xeroxes.
The chapter or section title is 'The Chrs [Chromosomes] & Feedback Systems in Evolution'.
Included is a group of papers titled 'Ch.4 Sexual Cycles'.
