Th0 author with his former resear 巴 h')indu 巴 edin general a differential equation on the assumption that the axile forces a 巴 ton any height of the beam ， at the same time under consid 日 rationof the height and changes of de 日 ectioncurves of the bearn as well as the effect of microhor ・ izontaldisplacements at the supporting points. He solved also those equations by means of the exhaustive theory of trans 巴 en-d 色 ntalfun 己 tion con 巴日 rn 日 d with the beam ， and calculated minutely the defiection angl 倒 的 ， 'P z and the axile for 冒 ce X.
