It is remarkable that each month the quantity ofarticles published on AIDS still that address numbers in the thousands. The basic, clinical and sociological aspects this epidemic have been vigorously investigated, and equally as extensively reported in traditional as well as new journals. Therefore, what can the reader ofthis volume expect to find that is different from the information already found in the literature? The authors of this text met in October 1993 to discuss not only AIDS and its effects on the nervous system but also to address the problem from the point of view of the diverse technologies that are used in understanding the disease. Just as the recog nition ofoncogenic viruses gave us insights into cellular genes that govern growth, the study ofHIV-I in the nervous system has opened new areas ofinvestigation in the nervous system. Use of human fetal and glioma-derived cell cultures, discovery of toxins in the nervous system, release and damage of cytokines in the brain, the neuropathic effects of HIV proteins, the investigation of new treatment for neuro AIDS, and virus detection strategies to identify latent HIVI infection are described in this volume. Basic and clinical investigators from more than thirty laboratories around the world contributed to the ideas discussed at the meeting, "Technical Advances in AIDS Research in the Human Nervous System.

First printing. "First edition" appears on the title page with no indication of a later printing. The pages are clean and unmarked. The binding/spine is tight and straight. The corners are sharp/unbumped. Unfortunately age or production paste deterioration have caused the spine and the board edges near it to appear stained or foxed. Similar discoloration appears along the near-spine edges of the pastedowns and front endpapers. The top text block is foxed. The jacket is in "good" condition. The bends are age discolored. There are some small abrasions along the spine, and there are three tears along the bottom edge, the longest two of which are about an inch long. There is light residue from a price sticker that was removed from the front flap where the original price of $3.50 appears.

This series of dialogues between the spiritual and the scientific is framed by Klein's deep knowledge of cell biology.

First published in 1999. This is Volume XVI of twenty-one of a series on Cognitive Psychology. Written in 1926, considered from a philosophic viewpoint, this is an English translation of Professor Rignano's work, Biological Memory," which gives an exhaustive analysis of the differences which distinguish living from non-living substance and his attempts to account for these differences as the manifold effects of a single quality.

It was a time of destruction of lives and futures and of rebirth and rebuilding. In his lively style with a wide sweep of insights Peter Lindenfeld recounts his personal and often intimate experiences, a microcosm of life during a time spanning nearly a century. The seemingly stable atmosphere of his childhood in Vienna is destroyed by the Anschluss, the annexation of Austria by Nazi Germany. The forced exodus leads him to North America, first to Vancouver, then to New York and a life that melds his original culture with that of his new environment, creating a richness-in science and music, and in intellectual and political life-that transcends both.

Twenty papers explore some of the diverse biological systems used in research today. Major systems are described in terms of the state of the art, advantages, disadvantages, and potential applications. The information presented will be most useful to graduate students and to all researchers interested in learning the limitations and assets of systems currently in use. Price to members is $24.95.

The Symposium on the Global Effects of Environmental Pollution has performed an important task; it has helped to determine the world-wide impact of certain types of local pollution and has uncovered certain unsuspected effects that might hold dan gerous implications for the future. This Symposium should help to make the world aware of a crisis that is becoming more ominous and that involves the developing as well as the developed countries - the crisis of the human environment. The causes of this crisis are not difficult to discern. There has been an unprecedented increase in the world's population, an ever-increasing rate of urbanization, and in many countries, a continuous process of industrialization. Essentially, advancing technology has made it possible for a minority of mankind to achieve affluence and holds out hope for improving the well-being of the great majority. But, because it has not been integrated into the natural environment, this very technology - in industry, in agriculture or in transport - is having many undesir able and potentially catastrophic consequences. Our air, our water and our soil are in grave danger. Many species of animal and plant life have become extinct or are facing extinction. The loss to mankind is grave and even the future oflife on earth may be in danger. The challenge is to find ways of repairing the harm already done and to prevent further harm.

Max Born (1882-1970) was a physicist and mathematician who won the 1954 Nobel Prize in Physics for his research in the area of quantum mechanics. Originally published in 1943, this book presents a slightly expanded version of an address Born gave to the Durham Philosophical Society and the Pure Science Society, King's College, at Newcastle-upon-Tyne on 21st May 1943. The text provides an examination of the mutual relationship between theory and experiment in the development of physics. This book will be of value to anyone with an interest in the works of Born, physics and the history of science.

My 'discovery' of the Polish School of philosophy of medicine stemmed from my studies in the genesis of Ludwik Fleck's epistemology. These studies, and my interest in the scientific roots of Fleck's epistemology were a nearly 'natural' result of my own biography: like Fleck I had been trained, an had worked as an immunologist, and had later switched to studies in the social history of medicine and biology. Moreover, it so happened that Fleck's book, Genesis and Development of a Scientific Fact -the description of a science as it is, not as it should be -was the first epistemological study in which I found echos of my experience in the laboratory. My interest in Fleck was also highlightened by the fact that in his works, and, as I discovered later, in the works of his predecessors of the Polish School of philosophy of medicine, was formulated the problem that had stimulated my interest in the history of medicine and biology, and is still central to my present investigations: the relationships between biological knowledge and clinical practice. The writing of the book was made possible through to the help of many colleagues and friends. The unfailing support for my research, whatever its subject might be, from my colleagues from Unit 158 of INSERM and in particular from its head Patrice Pinell, has made my study of the Polish School possible.

The publication of this book is extremely timely, for the next major advances in manned space flight after Project Apollo will most likely be made in earth orbital operations. Manned exploration of the moon will certainly continue after the initial landing, but it will be performed essentially with the Saturn V launch vehicles and Apollo spacecraft developed in Apollo, especially in the early phases. Modifications to this basic hardware will increase operating capabilities to permit extensive lunar explo ration during prolonged stay times by the astronauts on the moon's surface. Manned orbital space stations have been studied for years, and NASA is already well along in development of its first attempt to provide more spacious accommo dations for astronaut-scientists in its Saturn Workshop program. While the Workshop is certainly not the ultimate space station of which our technology is capable, it is a workable, poor man's approach to the immediate need for using and expanding our present manned space flight capability without a de trimentalloss of momentum. The approach of converting a Saturn rocket stage into a manned laboratory and observatory in space is an improvisation that matches the use of the jerry-built Jupiter C back in 1958 to launch Explorer I. Let's hope that it can get the job done just as effectively.
