Abstract
Regular daily fluctuations in spontaneous physical activity and in the mitotic indices of marrow and splenic erythroid elements and pinna cells, were observed. Both male and female C57Bl/6J mice showed these rhythms. Of particular interest was the finding that the spleen and the marrow mitotic activity showed a reciprocal relationship. The role of several hormones and the biological clock in control of these rhythms are discussed.
