The effectiveness of a drug in reducing susceptibility to acute motion sickness is readily determined in a slow rotation room (SRR) where the stressful Coriolis accelerations are under quantitative control and the experimenter and subject can collaborate under laboratory conditions. Fifty subjects were used, each serving as his own control, in evaluating 16 representative antimotion sickness drugs. Only the drugs with a sympathomimetic or parasympatholytic action and some of the antihistamines were notably effective. The summation effect of dextroamphetamine sulfate and 1-scopolamine hydrobromide provided far better protection than any single drug. Other classes of drugs had either a slightly favorable or slightly unfavorable action. (Author).

Roman triremes of the Mediterranean. The treasure fleet of the Spanish Main. Great ocean liners of the Atlantic. Stories of disasters at sea fire the imagination as little else can, whether the subject is a historical wreck - the Titanic or the Bismark - or the recent capsizing of a Mediterranean cruise ship. Shipwrecks also make for a new and very different understanding of world history. A History of the World in Sixteen Shipwrecks explores the ages-long, immensely hazardous, persistently romantic, and still-ongoing process of moving people and goods across far-flung maritime worlds. Telling the stories of ships and the people who made and sailed them, from the earliest ancient-Nile craft to the Exxon Valdez, A History of the World in Sixteen Shipwrecks argues that the gradual integration of localized and separate maritime regions into fewer, larger, and more interdependent regions offers a unique window on world history. Stewart Gordon draws a number of provocative conclusions from his study, among them that the European "Age of Exploration" as a singular event is simply a myth - many cultures, east and west, explored far-flung maritime worlds over the millennia - and that technologies of shipbuilding and navigation have been among the main drivers of science and technology throughout history. Finally, A History of the World in Sixteen Shipwrecks shows in a series of compelling narratives that the development of institutions and technologies that made terrifying oceans familiar, and turned unknown seas into sea-lanes, profoundly matters in our modern world.

In this book Robert V. Wells presents an exhaustive survey of recently discovered census data covering 21 American colonies between 1623 and 1775. He thus provides the first full-scale determination of basic demographic patterns in all parts of England's empire in America before 1776. Following an examination of the adequacy of the censuses, the author describes the population patterns of each colony for which a census is available. He presents information on size and growth of population; race, age, and sex composition; degree of freedom; household size and composition; marital status; military manpower; and birth and death rates. He concludes by describing important variations in demographic patterns from one part of the empire to another and the possible significance of those differences. Originally published in 1975. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Child labor law strikes most Americans as a fixture of the country’s legal landscape, involving issues settled in the distant past. But these laws, however self-evidently sensible they might seem, were the product of deeply divisive legal debates stretching over the past century—and even now are subject to constitutional challenges. Child Labor in America tells the story of that historic legal struggle. The book offers the first full account of child labor law in America—from the earliest state regulations to the most recent important Supreme Court decisions and the latest contemporary attacks on existing laws. Children had worked in America from the time the first settlers arrived on its shores, but public attitudes about working children underwent dramatic changes along with the nation’s economy and culture. A close look at the origins of oppressive child labor clarifies these changing attitudes, providing context for the hard-won legal reforms that followed. Author John A. Fliter describes early attempts to regulate working children, beginning with haphazard and flawed state-level efforts in the 1840s and continuing in limited and ineffective ways as a consensus about the evils of child labor started to build. In the Progressive Era, the issue finally became a matter of national concern, resulting in several laws, four major Supreme Court decisions, an unsuccessful Child Labor Amendment, and the landmark Fair Labor Standards Act of 1938. Fliter offers a detailed overview of these events, introducing key figures, interest groups, and government officials on both sides of the debates and incorporating the latest legal and political science research on child labor reform. Unprecedented in its scope and depth, his work provides critical insight into the role child labor has played in the nation’s social, political, and legal development.
