    The aniloethyl alcohol forms with fatty acid a compound, which is not promptly dissociated even by the presence of inorganic acid and dissolves into the organic solvents, such as ether or petroleum ether, especially when a large quantity of free fatty acid is present, contaminating thus the fatty acids with nitrogenous impurity in its turn.
    That the fatty acid obtained by hydrolysis of cephalin invariably retained a small amount of nitrogen, is thus easily explaiiable, and it might be well noted that the fat-determi-nation of any ceplialin containing organs will be affected by such a circumstance.

    1. The analytical result of 487 urinary calculi is given.
    2. A new classification of urinary calculi is advanced
    3. Oxalate nuclei are found in Japan most abundantly in contradiction to the current view.
    4. The urinary calculi in women are almost all phosphate calculi.
    The explanation on this phenomenon is afforded. The writer wishes to thank Professor S. Kakiu chi for advice throughout the course of the investigation.

  • I. Phlorhizin glycosuria and Renal activity

    We have examined the urea excreting activity of the kidney comparing the ratio (Urea in one hour's urine/Urea in Urea 100cc of blood) in control and in phlorhizised rabbits. It showed, as we can see in Table I and II, that the ratio in the control gives an average 1.90, while that in the case of phlorhizinised rabbits gives 1.84. It is evident from the results that the phlorhizin has no appreciable effect on the urea. excreting activity of the kidney.
    The average amount of sugar eliminated in urine by phlorhizinised rabbits was 1.30%.
    A slight diuresis after phlorhizin injection, as previously well known, occurred also in these cases.

    1. The special effect of calcium for the activation: of prothrombin into thrombin is shared by strontium.
    2. Calcium accelerates the coagulation of blood not only through the activation of prothronzbin into thrombin, but by promoting the formation of fibrin from. fibrinogen by thrombin.
    3. Thrombin is stable at the temperature below the body temperature. Its activity is maximum at body tem-perature.
    4. The identification of tissue throniboplastic substance with kephalin was confirmed.
    5. Kephalin maintains its thromboplastic character in full by the heating below 120°C. At higher temperature the activity is partly decreased.
    6. The hydrogenation has no effect on the thromboplastic activity of kephalin.
    7. The treatment of kephalin by nitrous acid or formalin causes the decrement of activity of kephalin as throznbo-kinase.
    8. By the complete hydrolysis kephalin lost its thrombo-plastic activity. Out of its decomposition products glycerin-phosphoric acid and aminoethylalcohol reveal no thrombo-plastic action. Stearate and aininoethylstearate especially the latter, promote, however, the coagulation of fibrinogen a great deal.
    9. Cholesterol exerts no influence upon the coagulation of plasma. Cholic acid in a great amount retards the coagulation both in presence and absence of kephalin.
    10. The influence of albumin in different concentrations on the velocity of coagulation in the absence and presence of kephalin in varying amount envea.ls a complicate, but regular relation, which needs a further study.
    11. The treatment of peptone plasma with trypsin induces the coagulation, the rate increasing tip to a certain point with the concentration of trypsin. This effect seems to lie in the hydrolysis of some inhibiting substance by trypsin. Further increase in trypsinn inhibit however the coagulation, possibly by its hydrolytic action on fibrinogen.
    12. Kephalin has no effect on the coagulation of fibrinogen by thrombin but in a large excess it tends to decrease the coagulation velocity.
