(1) The excretion of acetoin and acetic acid in the urine of normal rabbits is increased by the administration of thiamine.
(2) When pyruvate is injected into normal rabbits, acetoin in the urine for a while is increased.
(3) The injection of diacetyl increases the urinary excretion of acetic acid and acetoin, but that of diacetyl together with oxalacetate decreases the urinary excretion of acetate.
(4) The injection of acetic acid increases the urinary excretion of acetoin for a time.
(5) Injection of citrate causes the increased excretion of acetate, acetoin, and pyruvate in the urine, but citrate excretion remains always unaltered.
(6) Acetate excretion in the urine is decreased by the injection of oxalacetate.

The mode of locomotion of Ascaris was studied by means of the U-shaped glass tube method which had been recently reported by Kobayashi and Bando. The worm moves forward by making three or four undulatory curvatures of the body, which attach and then detach themselves in turn to the inner surface of the glass tube, reiterating such motions in order to push itself forward just like the inchworm. The period of a wave-like movement was measured by recording the time in which one wave-like curvature passed through a certain given part of the body. It was found that the frequency distribution showing the fluctuation of the periods of the movement belongs statistically to “normal type” which indicates the stable nature. There is also a close relationship between the velocity and the period of the movement which may be expressed by the following formula: X(Y-5)1.918=310.7 where X denotes the velocity in cm./min. and Y the period in sec. respectively. The velocity of the movement varies by changing the diameter of the glass tube in which the worm is observed, in such a manner as it depends upon the ratio between the diameter of the glass tube and the body length. The optimum velocity was obtained when this ratio lay between 1/11 and 1/16. Generally, the initial period of the movement of the worm was maintained within about 30 hours after being taken out of the inside of the pig bowel, while the initial velocity of it is observed only during about 10 hours exposure to the artificial solution. All the experiments were carried out in the modified Locke-Ringer solution maintained exactly at 32°C.
