Object Lessons and the Formation of Knowledge explores the museums, libraries, and special collections of the University of Michigan on its bicentennial. Since its inception, U-M has collected and preserved objects: biological and geological specimens; ethnographic and archaeological artifacts; photographs and artistic works; encyclopedia, textbooks, rare books, and documents; and many other items. These vast collections and libraries testify to an ambitious vision of the research university as a place where knowledge is accumulated, shared, and disseminated through teaching, exhibition, and publication. Today, two hundred years after the university’s founding, museums, libraries, and archives continue to be an important part of U-M, which maintains more than twenty distinct museums, libraries, and collections. Viewed from a historic perspective, they provide a window through which we can explore the transformation of the academy, its public role, and the development of scholarly disciplines over the last two centuries. Even as they speak to important facets of Michigan’s history, many of these collections also remain essential to academic research, knowledge production, and object-based pedagogy. Moreover, the university’s exhibitions and displays attract hundreds of thousands of visitors per year from the campus, regional, and global communities. Beautifully illustrated with color photographs of these world-renowned collections, this book will appeal to readers interested in the history of museums and collections, the formation of academic disciplines, and of course the University of Michigan.

This volume reviews recent developments in our understanding of che~ ical signaling in vertebrates. After sections dealing with general princi ples and chemical aspects of vertebrate pheromones, it follows a taxonomic approach, progressing from fish to. mammals. The editors asked a diverse, international group of leading investigators, working on a wide array of vertebrate taxa and specific issues, to consider their efforts from compar ative, evolutionary, and ecological viewpoints. The relative number of manuscripts in each part does not necessarily reflect current intensity of research, since the editors invited speakers who together would provide a balanced and comprehensive overview, while avoiding duplication. Still, the part on mammals is the longest. Fourth in a series dating from 1977, this volume illuminates current trends and likely future developments in the field of chemical signaling in vertebrates. Going back even farther, the first chapter, a personal account of the past quarter century by Dr. Mykytowycz recalls the most important milestones, such as symposia, or the founding of societies and journals. He also credits those investigators who stand out by their seminal studies.
Excerpt from Variations and Genetic Relationships of the Garter-Snakes Three steps are necessary to determine the genetic relationships and simplify Cope's elaborate arrangement of the group: (1) The value of the characters must be determined; (2) the geographic prob abilities must be utilized; (3) similarities and intergradations must be sought.

The Garter Snakes: Evolution and Ecology is the first comprehensive review of the genus Thamnophis in nearly ninety years. The book includes color plates of all species (many never previously figured in color); extensive discussion of ecology, behavior, and captive care; and a modern key to all species - as well as species-by-species summaries of the systematics and natural history of the thirty different garter snakes now recognized. Of particular interest are the descriptions of lesser-known species in Mexico. Because interest in reptiles has grown dramatically in recent years, this comprehensive guide is designed to appeal to as wide an audience as possible - to both the professional herpetologist interested in the biology of Thamnophis and the hobbyist who wants to know more about these diverse and widespread snakes, both in the home aquarium and in the wild. This up-to-date, appealing book, written by the world's leading authorities, will be extremely useful not only to herpetologists but also to conservationists, ecologists, pet owners, and other readers generally interested in natural history.
