Dear Dr. Lederberg:

During the past four years I have researched and written a book in which
I discuss the subject of life on other worlds in a sober, objective and con-
prehensive manner. The work, nearly completed and now entering the review
phase, runs to well over 600 pages and is pitched to the intelligent layman.
(I've taken the liberty of enclosing my most recent chapter outline so you can
see the breadth of coverage.) I have tried to accomplish several objectives:

(1) To assemble in one place the results of all pertinent researches,
writings, and reasonable speculations concerning extra-
terrestrial life published to date;

(2), To stimulate new ideas and to suggest possible new areas of
research; and

(3) To substantiate the oft-challenged claim that a scientific
field of study pertaining to extraterrestrial life (which
I call "xenology" for a variety of reasons) even exists.

In view of your long-standing interest in and many contributions to the
field, I thought you might be interested in having a look at Chapter 16 of
my book, entitled "Xenobiotechnology" (3lpp). If so, I would be most gratefulrr, 20 1979
for any comments or suggestions you might care to make generally on "y book

as a whole or specifically on Chapter 16.
