    PAGE Portal Blood in relation to Ingested Caebohyjeates. Amount of sugar in blood of general circulation. Procedure for obtaining portal blood. Cupric oxide reducing power of sugar of portal blood and that of other blood. Amount and nature of sugar in portal blood—after fasting—after animal food—after starchy food—after maltose—and after cane sugar 101 The Lives in relation to the Sitgae deeited feom: Ingested Caebohydeates. Evidence afforded through the Blood of Sugar being stopped by the Liver. Comparative states of the blood of the portal and hepatic veins. Precautions requisite in collecting blood for analysis to avoid fallacy from post-mortem change. Amounts of sugar encountered immediately after death in portal and hepatic b'ood. Sugar arresting function of liver the protection against diabetes. Evidence afforded through the Liver itself of the stoppage by it of sugar derived from Ingestion. Bernard's allegation of a sugar-forming function of the liver. His discovery of glycogen. Ingested carbohydrate a source of glycogen. Grlycogen also formed from ingested animal food. Both free and combined carbohydrate in animal matter. Proteid cleavage the work of digestive ferments not of the liver. General relations of glyco- gen as a constituent of the liver. Not easily extracted. Amount in the liver. Its diminution, from post-mortem transformation. Eange of figures met with—influence of food—variation with age—variation with kind of animal 109 The Litee in eelation to Constituent Sugae. Procedure necessary for ascertaining the nature of the sugar. Eapid post-mortem production of sugar in the liver. Prevention of post-mortem change by boiling and by freezing. Amount and nature of sugar found in the liver respectively before and after the occurrence of fost-mortem change. Influence exerted by the body-temperature existing at the time of death. State found in the liver of cold-blooded animals. The amount of sugar present in the liver corresponds with that met with in the other structures of the body. The sugar-forming ferment under an inhibitory influence during life. The inhibitory influence removed under certain abnormal condi- tions. Analogy of the conditions attaching to the coagulation of the blood. Production of sugar in a liver removed and washed free from blood. The ferment possesses a glucose-forming capacity. Production of sugar in liver-substance previously coagulated by alcohol. Proof that the change is not due to living action. Production of sugar in alco- hol-coagulated liver-substance increased in presence of blood. Influence of sodium carbonate and citric acid on ferment change in the liver 132 The Blood in eelation to Sugae. Nature of sugar present in blood- glucose. Portal blood an exception. Amount of sugar present in blood—varying statements of diflerent observers. Special precautions necessary in the collection of the blood for analysis. The condition of the urine an index of that of the blood. Arterial and venous blood in relation to sugar—alleged difference—source of the fallacy—precau- tions required in experimenting to escape from it. Results given.
