The Lives of a Cell by Lewis Thomas (1974, ISBN 978-0-14-004743-1)
Subtitle-- Notes of a Biology Watcher.
This book contains a series of essays originally published by the New England Journal of Medicine. I enjoyed these essays, found interesting. A few time I found stuff that was out of date, nut that should be no surprise, since they were written more than 40 years ago. Was an xmas gift, xmas 2015.

Soul On Ice by Eldridge Cleaver. 1968. This book is a collection of essays and letters written over a period of several years. At the time it was highly provocative. The first two sections were interesting, the final section seemed to me to be a bit silly.
