This book has been conceived as a reference for all those who want to deepen their knowledge of technical details, design concept and interac tion of the individual modules of Zeiss operation microscopes. The sub jects of the book are classified in accordance with our intention. Special emphasis has been placed on practical hints for the user of opera tion microscopes to avoid operating errors. Parameters which are of para mount importance for surgeon and assistant such as PD and diopter set ting are therefore described in detail. The effects of wrong adjustments are indicated. The above statements also apply to the ample selection of acces sories for Zeiss operation microscopes. That is why much attention has been given to the accessories for co-observation and documentation. The most frequently used formulae are liste in the last chapter of the book, supplemented by nomograms which allow the reader to determine the most important data of a specific piece of microscope equipment without calculation. Our thanks are due to all those who assisted in preparing the manuscript, drawings and photographs, to Mrs. Ursula Gabler for making the English translation and Miss Helen Robertson for editing it, and last but not least to the Springer-Verlag for the most careful, qualified and excellent pro duction of the book."

Investigations of the oxygen carriers range from the characterization of natural populations to measurements of tenths of nanometer distances between atoms. The scope is so great that few biologists and biochemists can fully comprehend the primary literature in its entirety. In addition, the findings of the past two or three decades have advanced the field so rapidly that a truly current account is not readily accessible to a general audience. In recognition of the problem a symposium was held and its proceedings published in the American Zoologist in 1980. Although it included several research reports, most of the contributions were intended to summarize then state-of-the-art information on molecular structure and respiratory function at a level that could be understood by biologists and biochemists who are not experts on our subject. Judging from the reprint requests with which the authors were inundated, the assessment of need had been accurate. I believe that the need for an update, which is wholly focused on communication to the general audience, is even greater in 1992. I therefore asked the authors of this volume to address individuals who might otherwise turn in vain to an advanced textbook of physiology or biochemistry. I have, of course, requested a more comprehensive coverage than would be possible in a general text, but one that is not more parochial. Just as textbooks differ vastly in the level at which their subject matter is presented, so the level of non-expertise was conceived differently by the contributors to this volume.
