Clock of Living Nature, The

This book is the first attempt to summarize in popular form extensive experimental materials dealing with the extremely interesting problem of biological rhythms. It will take the reader into the exciting world of living nature, into the mysterious cell, following processes of metabolism, the movements of leaves and petals, and fishes and birds on long-distant migrations. He will see that all organisms --from unicellular to highly organized animals including man-- measure time and that the material unity of living nature is also demonstrated by the identical organization of physiological processes in time.
