   • Page 1A subheads include (but are not limited to):
   1. Hosts
   2. Diverse properties
   3. Recombinational events

   5. Origin
   6. Evolution
   • Page 1B appears to be detailed notes for the introduction

10. Typed handout or slide: "The Day Of The Plasmids?"

11. Visual: "P. lac (an episome from Proteus)"

12. Typed handout or slide: "Some Properties of Medical Interest Coded by Plasmids"

14. Manila folder:

    • Department of Medical Microbiology Genetics Group announcement of Esther M. Zimmer Lederberg speaking about Pseudomonas Plasmids on Thursday, January 15, 1975, 4:15 pm Conference Room

    • Six handwritten pages of notes, beginning with page 1C (related to the pages 1A and 1B above?)

    • Seven pages typed on perforated paper (unseparated), with the heading "Outline of answers to your 7 questions; Informal Draft only"
      Various drafts of the answers to 7 questions (questions not found in this folder). ¹
      The answers given talk about the beginnings of the field of bacterial genetics, including:

      1. The history of experiments by J. Lederberg and E. Tatum described in CSH 1946
      2. The discovery of F, the terms "plasmid", "mating", "conjugation", "sex"
      3. A general discussion of how terminology is derived and why some terms survive and others do not
