The changes in T_I (especially positive TI) height of guinea pig in each experimental course were investigated. A. Exp. I (Head→Tail×10") T in all cases shows the enlargement during exposure to the acceleration (3.5, 6, 8g). (Enlarged type). The time indicating the maximum enlargement of T during exposure to the acceler and the time returning to the original T-height after the cessation of centrifugalization are almost the same as those of P in the same kind of experiment, (see the Report I). Generally the max. enlargement (%) is likely to be greater in accordance with the increase of the magnitude of g exposed. B. Exp. II (Tail→Head×10") The general type of change in T-height in the experiment (3.5, 6g) is the "Reduced type," and the times indicating the max. reduction of T and returning to the original T-height in the experimental course are nearly the same as those of P in the same kind of expenment. The max. reduction (%) seems to be smaller in 6g rather than 3.5g-expeiment. C. Exp. III (to L. & R. along the Transverse axis×10") The general type of change in T-height is the "Enlarged type," and it's change in the experiment (3.5, 6g) is the very same as that seen in Exp. I. The max. enlargement (%) is nearly equall in the same g-experiment, even though the acceler. is directed to either L. or R., and is likely smaller than that in the same kind of experiment in A.
