The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

When this monograph was published almost 30 years ago, then History and Museums Director Brigadier General Edwin H. Simmons wrote: "Today's generation of Marines serve in a fully integrated Corps where blacks constitute almost one-fifth of our strength. Black officers, noncommissioned officers, and privates are omnipresent, their service so normal a part of Marine life that it escapes special notice. The fact that this was not always so and that as little as 34 years ago (in 1941) there were no black Marines deserves explanation." This statement holds true for this edition of Blacks in the Marine Corps, which has already gone through several previous reprintings. What has occurred since the first edition of Blacks in the Marine Corps has been considerable scholarship and additional writing on the subject that deserve mention to a new generation of readers, both in and outside the Corps. First and foremost is Morris J. MacGregor, Jr.'s Integration of the Armed Forces 1940-1965 (Washington, D.C.: U.S. Army Center of Military History, 1981) that documents the Armed Forces efforts as part of the Defense Studies Series. The volume is an excellent history of a social topic often difficult for Service historical offices to deal with.

To a certain extent the dementias have been forgotten diseases until just recen tly when they were brought to the attention of the general public and health authorities as a result of the increasing number of cases in the aging popula tion, especially among famous people, and because of the efforts of private foundations. The goals of the present volume are to present the dementias to health prac titioners, to provide some basic information on their epidemiology and biolo gical basis and to discuss the diagnostic and clinical problems that physicians and institutions face when caring for demented patients. This book explores the various types of dementias and is not limited to Alzheimer's disease although, as expected, more information is available and presented on this pathology. On the other hand, a few fundamental questions on dementia can only be answe red through a comparison of the various forms. Examples of such questions are the following: Is the loss of cerebral tissue sufficient to cause dementia? Are there thresholds or is there a continuous progression toward the irreversible development of dementia? Are there common pathways in the dementing pro cess? Are there common risk factors? Comparative analysis allows the common and distinctive patterns of the various dementias to be defined, ultimately lea ding to more focused therapeutic interventions.
