Corn is among the most familiar of grains; it is also one of the most mysterious. In this handsomely illustrated new book, Paul Mangelsdorf, perhaps the world's foremost expert on the corn plant, summarizes the work of a lifetime devoted to unraveling the enigma of corn.

This unique grain--it has no close counterpart elsewhere in the plant kingdom--exists only in association with man, and it survives only as a result of his intervention. Thus, the story of corn is in many ways a story about people. Combining the skills of scientist and storyteller, Professor Mangelsdorf in his search for the origin of corn takes the reader to archaeological digs in once-inhabited caves in Mexico and the United States Southwest, to the discovery of fossil pollen in drill cores taken deep below Mexico City, and to experimental fields where the great diversity of corn is revealed and where the plant is hybridized with its relatives teosinte and Tripsacum.

Drawing upon the evidence from botany, genetics, cytology, archaeology, and history, the author seeks to evaluate various hypotheses on the origin of corn. He concludes that the ancestor of cultivated corn was a wild form of pod corn; that corn may have been domesticated more than once in both Mexico and South America from different geographical races of wild corn; and that hybridizations between corn and its various relatives have resulted in explosive evolution leading to a diversity of varieties and forms unmatched in any other crop plant.

This is a book about corn, but it is a book for biologists, agronomists, anthropologists, and historians, and for the interested layman who would like to know something about the grain which, "transformed, as three fourths of it is, into meat, milk, eggs, and other animal products, is our basic food plant, as it was of the people who preceded us in this hemisphere."

Varieties of the house mouse, long reared in captivity as pets, in recent years acquired importance as instruments of scientific investigation. Mice are used extensively by medical schools and hospitals in the diagnosis of disease and in the preparation or standardization of serums to combat disease. They have also been of great service in the study of heredity because of their short life-cycle, the large number of their known inherited characters, and the assurance that laws of heredity valid for mice are likely to be valid for man since he also is a mammal. Extensive use of mice by scientists leads to a desire on their part to learn as much as possible about mice, including their origin and history as a domestic animal, their uses in times past and at present, and the best methods of rearing them and keeping them free from disease. All this and much more Dr. Keeler has discussed in this timely and well-illustrated volume, which will be particularly welcome to students of genetics as a companion volume to Castle’s Genetics and Eugenics and The Genetics of Domestic Rabbits.

The Samaritan Pentateuch (SP) is the sacred scripture of the Samaritans, a tenacious religious community made famous by Jesus’ Good Samaritan story that persists to this day. Not so widely known is the impact of the SP outside the Samaritan community. Recently there has been a resurgence of interest in this scripture, as evidenced by several translations of the SP as well as reference in Qumran scroll studies to the SP or an SP-like tradition in an effort to describe some of the textual evidence present in the scrolls. This volume presents a general introduction to and overview of the SP, suitable for a course text and as a reference tool for the professional scholar.
