NOTE: Because some pages have duplicated pagination while other pages have been removed from the original by the author, page ranges don't necessarily reflect the actual number of pages in this document. Pages 1152, 1156-1157, 1160, and 1163-1168 have duplicate pagination. Page 1151 was part of a different set of experiments and can be found as part of Lederberg laboratory notebook, "Experiments in Motile Lines".
