consequences of broken symmetry -here parity-is studied. In this model, turbulence is dominated by a hierarchy of helical (corkscrew) structures. The authors stress the unique features of such pseudo-scalar cascades as well as the extreme nature of the resulting (intermittent) fluctuations. Intermittent turbulent cascades was also the theme of a paper by us in which we show that universality classes exist for continuous cascades (in which an infinite number of cascade steps occur over a finite range of scales). This result is the multiplicative analogue of the familiar central limit theorem for the addition of random variables. Finally, an interesting paper by Pasmanter investigates the scaling associated with anomolous diffusion in a chaotic tidal basin model involving a small number of degrees of freedom. Although the statistical literature is replete with techniques for dealing with those random processes characterized by both exponentially decaying (non-scaling) autocorrelations and exponentially decaying probability distributions, there is a real paucity of literature appropriate for geophysical fields exhibiting either scaling over wide ranges (e. g. algebraic autocorrelations) or extreme fluctuations (e. g. algebraic probabilities, divergence of high order statistical moments). In fact, about the only relevant technique that is regularly used -fourier analysis (energy spectra) -permits only an estimate of a single (power law) exponent. If the fields were mono-fractal (characterized by a single fractal dimension) this would be sufficient, however their generally multifractal character calls for the development of new techniques.

In seventeenth- and eighteenth-century England and America, established society branded as "enthusiasts" those unconventional but religiously devout extremists who stepped across orthodox lines and claimed an intimate, emotional relationship with God. John of Leyden, Anne Hutchinson, William Penn, and George Whitefield all shared the label "enthusiast." This book is a study of the enthusiasts who migrated to the American colonies as well as those who emerged there--from Pilgrim Fathers to pietistic Moravians, from the martyr-bound Quakers to heaven-bent revivalists of the 1740s.

This study of the role of religious enthusiasm in early America tells us much about English attitudes toward religion in the New World and about the vital part it played in the lives of the colonists. Both friends and enemies of enthusiasm revealed in their arguments and actions their own conceptions of the America they inhabited. Was religion in America to be an extension of Old World institutions or truly a product of the New World? Would enthusiasm undermine civilized institutions, not only established churches, but government, social structure, morality, and the economy as well? Calling enthusiasts first heretics, then subversives and conspirators, conventional society sought ways to suppress or banish them. By 1776 enthusiasm had spilled over into politics and added a radical dimension to the revolutionary struggle.

This timely exploration of the effect of radical religion on the course of early American history provides essential historical perspective to the current interest in popular religion.

An outstanding examination of the crises that lead to the colonial rebellions of 1689. A finalist for the National Book Award for history in 1973, the book is now available in paperback with a 1987 introduction by the author. "Lovejoy has now related this whole period of history] more fully than it has ever been told before. His research is thorough, and his reach in time and space is impressive . . . a judicious and significant book, the best we now have on the subject"-- New York Times Book Review. "A long-awaited assessment of those critical upheavals that disrupted the American colonies from Bacon's Rebellion in 1676 to the major revolts in New England, New York, and Maryland in 1689. Lovejoy's] interpretation is decidedly neo-Whig, which should provoke a fine narrative of the period and a most provocative comparison of these important revolutions, a comparison that should challenge all students of the colonial political process." - The American Historical Review DAVID S. LOVEJOY us a professor emeritus of history at the University of Wisconsin, Madison, where he taught from 1960 to 1983. He received a B.S. from Bowdoin College in 1941 (and Distinguished Bowdoin Educator Award in 1980) and Ph.D. from Brown University in 1954. LOVEJOY has taught at Northwestern and Brown universities and a t Marlboro Colege in Vermont. Her was a Fulbright Lecturer in Scotland and has received Guggenheim and Rockerfeller Foundation fellowships. He is the author of Religious Enthusiam in the New World: Heresy to Revolution. His home is in Madison and in Oxford-shire, England.
