I would like to thank all my co-workers who have collaborated with me, from 1963 until now, in biological and clinical research in the field of cancer active immunotherapy, of its immuno prevention and immunorestoration. They will often be quoted in this book. I am particularly grateful to those who have helped me to write it by reviewing some chapters: D. BELPOMME, J. F. DOR~, IRENE FLORENTIN, A. GOUTNER, I. J. Hm, R. HUCHET and MARIE-CHRISTINE SIMMLER. I also thank NICOLE VRIZ, MARIE-CLAUDE SCHNEIDER, FENELLARIsELEY and M. JUVET for their willing and efficient co-operation in the preperation of the manuscript. I am finally grateful to all authors of books or articles who authorized me to reproduce their figures or tables. Paris, April 1976 G. MAT~ Contents Chapter 1.
