In the previous report the author got general solution and solved several examples. But the general solution is not proper to solve practical problems, because in order to determine unknown coefficients he should solve simultaneous linear equations of infinite dimensions. In this report the author reforms the general solution, and by this improvement he can get unknown coefficients by solving finite equations. He solves several examples and gets same solutions as those of H. Neuber's.
