This book, published without preface, introduction or editor's note, consists of twelve short papers by as many different authors. These papers were read as part of the University of Pennsylvania bicentennial conference. The contents of the book are best indicated by listing the titles of the papers and their authors:

Chromosomes and Heredity: The Nature of the Gene. M. Demerec.

Chromosome Structure. Charles W. Metz.

Cytogenetics and Evolution. Albert F. Blakeslee.

Chromosomal Differences Between Races and Species in Drosophila. T. Dobzhansky.

Evolution of the Germplasm. Clarence E. McClung.

Cytology and Genetics of Protozoa: Heredity Status of the Rhizopods. Herbert S. Jennings.

Nuclear Behavior and Reproduction in Ciliated Protozoa. William F. Diller.

Inheritance in Ciliated Protozoa. T. M. Sonneborn.

Physiology of the Nucleus: The Physicochemical Properties of the Nucleus. Leon Churney.

The Chromosomes of the Amphibian Nucleus. William R. Duryee. Radiation and Cell Nucleus. Paul S. Henshaw.

As the reader will see from the titles, the conference concerned itself with frontiers of research and speculation in the highly technical field of cytogenetics. The book is a difficult one for any but the advanced student of genetics. It records
