    Effect of hydrogen ion concentration, MgCl2 and phosphate on the tissue respiration of rabbit kidney cortex was investigated by Warburg's second method.
    (1) Three kinds of Ringer's solution of pH 7.02, 7.20 and 7.42 were prepared by varying the bicarbonate concentration of the solution against the definite concentration of CO2 gas. The tissue respiration in these various solutions was compared with that in the normalRinger's solution of pH 7.32, and it was found that no marked dif-ference was caused by the variation of pH in these ranges.
    (2) Ringer's solutions of three kinds of MgCl2 concentration, i.e., 1, 5 and 10 mgm per cent were prepared and the tissue respiration was measured against that in the normal Ringer's solution.
    It was proved that MgCl2 seemed to be indifferent to the tissue respiration in vitro at such concentrations.
    (3) 45, 90 and 180 mgm per cent phosphate was added to 100cc Ringer's solution, and the tissue respiration was estimated by comparing with that in the normal Ringer's solution.
    The tissue respiration was increased with the increase of phos-phate in the Ringer's solution.

    Effect of urea, creatine, taurine and viscosity upon tissue respira-tion of kidney cortex of rabbit was investigated by Warburg's methods.2)3)
    (1) Addition of 20 mgm per cent urea to Ringer's solution caused no appreciable influence on the tissue respiration.
    (2) By the presence of 2 mgm per cent creatine in Ringer's solution the tissue respiration was hardly affected.
    (3) 10 and 20 mgm per cent taurine in Ringer's solution elevated the rate of tissue respiration slightly.
    (4) Tissue respiration in serum was greater than that in viscous Ringer's solution. (The Ringer's solution was made as viscous as serum by the addition of the definite quantity of gelatin.)

    Dass Winterfrösche auf die Darreichung des N-Methylpapaverins im Unterschied zu Sommerfröschen mit einer curareartigen Lähmung reagieren, ist auf eine Erregbarkeitsänderung der motorischen Nerven infolge einer Verminderung des Schilddrüsenhormons zurückzuführen. Dass das Papaverin nur bei männlichen Winterfröschen eine Reflexsteigerung verursacht, scheint von einem besonderen Zustand des Zen-tralnervensystems abhängig zu sein, das einerseits durch eine Vermin-derung des Schilddrüsenhormons, andererseits durch die Anwesenheit des Hodenhormons herbeigeführt wird.

    1. Glykogenbildung in der Leber bei nicht avitaminösen Kaninchen wird durch Zusatz von Vitaminen verschieden beeinflusst. Vitamin C wirkt unter anderen darauf weitaus am stärksten anregend, B1-sowie B2-Faktor nur mässig, während A and D fast keinen Einfluss austiben.
    2. Die Glykogenbildung anregende Wirkung der Vitamine lässt sich am deutlichsten bei den vorher mit Lezithinaufschwemmung intravenös behandelten Tieren nachweisen, bei welchen das vorgebildete Glykogen aus der Leber vollständig evakuiert wird, ohne dabei die Funktion des Organs allzusehr zu schädigen. Tiere mit reichlichem Vorratglykogen reagieren darauf weniger empfindlich.
    3. Die Leber der chloroform-oder phosphorvergifteten Tiere, die stets mit Glykogenschwund and Fettinfiltration einhergeht, kann man durch gleichzeitige Anwendung von Vitamin C and Glukose erfolgreicher als durch einfache Zuckergabe behandeln, da das Organ durch jene weit mehr an Glykogen gewinnt auf Kosten des Fettgehaltes als diese.
    4. Die Wirkung der Vitamine auf die Glykogenbildung in der Leber hat ein Optimum in Mengenverhaltnis; eine zu grosse Vitamin-menge schadet eher die Glykogenese.

    Dogs, narcotized with morphine, and rabbits without narcosis, were fastened on the operation table and prepared for the blood pressure recording.
    The minimum pressoric dose of adrenaline hydrochloride was estimated on intravenous application. Blood of various amounts were bled from an artery, and while the mean arterial pressure was low, the minimal pressoric dose of adrenaline was then tested.
    In dogs, bleeding of such a moderate amount as ten to thirty per cent of the total blood volume acts to lessen the minimal pressoric dose of adrenaline in the long run, but an excessive bleeding such as sixty per cent or more of the total blood volume acts to enlarge it.
    In rabbits the present writer found a reduction of the minimal pressoric dose of adrenaline in some among the cases where bleeding was small, and an increase when it was 2 per cent of the body weight or more.
