No one in this century can speak with greater authority on the progress of ideas in biology than Ernst Mayr. And no book has ever established the life sciences so firmly in the mainstream of Western intellectual history as The Growth of Biological Thought. Ten years in preparation, this is a work of epic proportions, tracing the development of the major problems of biology from the earliest attempts to find order in the diversity of life to modern research into the mechanisms of gene transmission.

Have you every wanted to build a sundial or to understand how one works? Then you have probably been frustrated as you search vainly for help. Most books on the subject are either rare out-of-print works published centuries ago and available only in highly specialized collections, or highly complicated treatises whose information is hidden behind frightening arrays of involved formulas. But now your search is over. This book is designed to meet sundialing needs at either the simple or the sophisticated level.
Albert E. Waugh, professor and administrator at the University of Connecticut for 40 years, and an expert on the subject of sundials and their curious history, presents, on the one hand, a rigorous appraisal of the science of sundials, including mathematical treatment and an explanation of the pertinent astronomical background; on the other hand, he presents simple and non-technical treatments such that several of the dials can be built by children
The subject matter is arranged in 19 chapters, each covering a different aspect of dialing science. All the common types of dials are covered, but the reader can also learn about analemmatic dials, polar dials, equatorial dials, portable dials, memorial dials, armillary spheres, reflected ceiling dials, cross dials, and old-fashioned noon marks. There are also sections on dial furniture, mottoes, the actual layout out of a dial, the equation of time, finding time in other cities, how to find the meridian, how to find time by moonlight -- even how to estimate time from the length of one's own shadow Directions are given for designing dials for any part of the country, or any place in the world. The author has designed many dials, and his text is filled with helpful hints based on his own personal experience. There are over 100 illustrations, charts, and tables, followed by an appendix which is filled with material which reduces or eliminates the need for calculation on the part of the reader.

"West with the Night" is the story of Beryl Markham--aviator, racehorse trainer, beauty--and her life in the Kenya of the 1920s and '30s.

Pieces of the Frame is a gathering of memorable writings by one of the greatest journalists and storytellers of our time. They take the reader from the backwoods roads of Georgia, to the high altitude of Ruidoso Downs in New Mexico; from the social decay of Atlantic City, to Scotland, where a pilgrimage for art's sake leads to a surprising encounter with history on a hilltop with a view of a fifth of the entire country. McPhee's writing is more than informative; these are stories, artful and full of character, that make compelling reading. They play with and against one another, so that Pieces of the Frame is distinguished as much by its unity as by its variety. Subjects familiar to McPhee's readers--sports, Scotland, conservation--are treated here with intimacy and a sense of the writer at work.

In this volume, the author discusses the fundamental Greek contributions to science, drawing on the rich literary and archaeological sources for the period after Aristotle. Particular attention is paid to the Greeks' conceptions of the inquiries they were engaged on, and to the interrelations of science and philosophy, science and religion, and science and technology. In the first part of the book the author considers the two hundred years after the death of Aristotle, devoting separate chapters to mathematics, astronomy, and biology. He goes on to deal with Ptolemy and Galen and concludes with a discussion of later writers and of the problems raised by the question of the decline of ancient science.

This special edition of the highly acclaimed A Sand County Almanac commemorates the one-hundredth anniversary of the birth of Aldo Leopold, one of the foremost conservationists of our century. First published in 1949 and praised in The New York Times Book Review as "full of beauty and vigor and bite," A Sand County Almanac combines some of the finest nature writing since Thoreau with an outspoken and highly ethical regard for America's relationship to the land.
