From the 98 presentations of the XIIth Symposium on Colour Vision Deficiencies, 61 were selected after peer review and revision by the authors. In addition to these contributions this volume contains a cumulative index to all authors in the IRGCVD proceedings since the first one in 1968, including the present volume. The contents include contributions on basic questions of anatomical and electrophysiological organisation of the neural pathways underlying colour vision; and on ways in which disturbances of these pathways can produce acquired colour vision deficiencies. Further contributions deal with genetics and congenital red--green colour deficiencies and colour vision testing. The resulting publication contains much of interest to basic vision scientists as well as to specialists in colour vision deficiencies.

Since its inception, the International Research Group on Colour Vision Deficiencies (IRGCVD) has followed the policy that the Symposium Pro ceedings should be as close as possible to a complete record of the scientific content of the meeting. This policy has the advantage of providing an accurate picture of the current state of the art in research on color vision deficiencies, but it also has the disadvantage that papers typically span a wide range of quality. In this volume, however, we have instituted a system of peer review in an effort to enhance scientific quality as much as possible while continuing our past policy of publishing all submitted manuscripts. In addition to being edited for English composition and grammar, each of the papers included here has been carefully reviewed by an IRGCVD member selected for his or her expertise in the specific topic of the paper. Reviewers were instructed to include in their comments suggestions for improvement rather than recom or rejection. In our opinion, this review process mendations for publication has resulted in substantial improvement of many of the articles and has enhanced the value of the publication. We are pleased to acknowledge the efforts of our reviewers and offer them our sincere thanks for their important contributions to Colour Vision Deficiencies X. The Editors B. Drum, J. D.

Proceedings of the symposium held in Annapolis, Md. July 1987.

In an industry that celebrates extravagance and showmanship, Danish film director Carl Th. Dreyer was a rarity, a man who guarded his privacy fiercely and believed that film provided a way to understand human nature by focusing on the individual person. Best known for his 1928 film The Passion of Joan of Arc, dominated by its emotionally harrowing close-ups of Joan during her trial, it was Dreyer who pioneered some of the seminal techniques of modern film, techniques that would later be made famous by better known contemporaries such as Sergei Eisenstein and D.W. Griffith. Now, in My Only Great Passion, the first full-length English language biography of Dreyer, Jean and Dale D. Drum restore his reputation to its rightful place. Based on extensive and exclusive interviews with both Dreyer and the people who worked with him-including personal correspondence dating back to 1952-this biography provides the most comprehensive critical examination to date of both Dreyer's life and his approach to filmmaking. A valuable resource for film critics and historians, those in the film industry, and university cinema departments, as well as anyone with an interest in Danish art and culture, My Only Great Passion provides long neglected insights into the man who first raised European film above the level of entertainment and placed it in the realm of art.

The eleventh Symposium of the International Research Group on Colour Vision Deficiencies (IRGCVD) was held 20-23 June 1991 in Sydney, Aus tralia, ably hosted by local organizer Stephen Dain. A total of 35 talks and 10 posters were presented. Papers based on 37 of these presentations are included here, in Colour Vision Deficiencies XI. The scientific program featured sessions on three special topics, with each topic highlighted by an invited speaker. The opening session on the Genetics of congenital colour vision deficiencies began with a superb invited lecture by Charles Weitz about his pioneering work on the molecular genetics of tritanopia. The session on the second special topic, Spatial aspects of colour vision, began with the launching of a new IRGCVD tradition, as 1991 Verriest Memorial Award recipient Harry Sperling presented the first Ver riest Memorial Lecture on his recent studies of spatial discrimination of heterochromatic stimuli. Dr. Sperling reported new evidence that certain asymmetries in red-green opponent colour vision can be explained by the spatial organization of colour-opponent retinal neurons. In the third special session, on Occupational aspects of colour vision, Barry Cole took the audi ence on a fascinating tour of the historical development of colour vision standards in his invited lecture entitled 'Does defective colour vision really matter?'. In addition to the three special topics, many interesting presentations were given in topical sessions on Variations in normal colour vision, Acquired colour vision deficiencies and Colour vision tests and testing methods."

Proceedings of the Ninth symposium of the International Research Group on Colour Vision Deficiencies, held at St. John's College, Annapolis, MD, July 1-3, 1987.

Medal of Honor recipient Jack H. Lucas's classic memoir of his heroics at the Battle of Iwo Jima-with a foreword by Bob Dole and reissued to coincide with the 75th anniversary of the battle in 2020. On February 20, 1945, the second day of the assault on Iwo Jima-one of the bloodiest battles of the Pacific theater in World War II-Private Jack Lucas, who was only seventeen, and three other Marines engaged in a close-proximity firefight with Japanese soldiers. When two enemy grenades landed in their trench, Lucas jumped on one and pulled the other under his body to save the lives of his comrades. Lucas was blown into the air as his body was torn apart by 250 entrance wounds. He was so severely wounded that his team left him for dead. Miraculously, he survived. While on the hospital ship Samaritan, his spirit soared to see the American flag flying atop Mount Suribachi-the same flag immortalized in Joe Rosenthal's iconic photograph, Raising the Flag on Iwo Jima. Lucas endured twenty-one grueling surgeries and carried 200 pieces of shrapnel in his body for the rest of his life. Awarded the Medal of Honor, he became the youngest Marine in U.S. history-and the youngest of all World War II servicemen-to receive the honor. Indestructible tells the remarkable story of an extraordinary American possessed with a fierce determination to serve his country.

This easy-to-ready field index will provide any technical person with the information and tools that they need to respond to many types of hazardous materials incidents. This index should be used to avoid potential deleterious incidents by quickly identifying the problems associated with mixing chemical and common substances. The book begins with an introduction, discussion, identification and definition of symbols, applications and examples of how to use the text. The chemicals are listed alphabetically with Reactivity Group Numbers (RGN). These numbers are identified in a table in both rows and columns in a chart. Chemicals, which react the same under a set of conditions, are listed together under the same RGN group of reactants in the back of the text. A list of alternative names for specific chemicals is provided in the index. Each example of chart interpretation is detailed in a step-by-step procedure. The procedure or interpretation of the results of mixing two or more chemicals is found in a quick and easy format.
