A fact of which we shall see some practical proofs further on. But to return to figs. 4 and 5, I give them to show that the effect of 1 oz. of sugar (containing no albu- mens) on the excretion of urea, is very slight compared with the effect of 1 oz. of cheese, and that this small effect is probably indirect and due to the sugar alter- ing the alkalinity of the blood and so affecting the circulation in the tissues and the removal of waste j)roducts from them. We have thus far learned, then, that the produc- tion of force requires :— (1) A sufficient supply of albumens in a digestible form. (2) A satisfactory interstitial circulation of the blood to carry these albumens to the tissues and remove waste products, and to make this possible the blood must contain little or no uric acid or similar substances, such as the xanthins. Before I leave the subject illustrated by the above figures of urea excretion, I will just point out that:— A small quantity of milk, cheese, or any food of similar albumen value causes a feeling that hunger is sated as the urea rises, and the feeling of hunger
