1. The effects of exercise and of postural change on counts of the blood platelets, erythrocytes and leucocytes were investigated on groups of healthy young men. 2. The platelet count decreased significantly after 10 minutes of moderate exercise, and showed a partial return to its original level when the subject stood still for the next 20 minutes. 3. The platelet count decreased significantly on standing up, and was still significantly depressed 10 minutes later. 4. The platelet count did not change significantly within 10 minutes of lying down. 5. Apart from a tendency for the leucocyte count to increase with exercise and a significant fall thereafter, the changes in erythrocyte and leucocyte counts were of minor degree. 6. The theoretical and clinical importance of these observations is discussed.
