THIS leads us to remark that no mere policy of tinkering can meet the requirements of the case. Mr. Banerjea, indeed, seemed to think that it was possible so to modify the Bill in the Select Committee as to make it comparatively innocuous. We doubt if such purification of the measures is possible. It is the principles of the Bills, the essential, fundamental principles of them, which the public cannot accept, and Sir William Vincent had these principles and no mere detail in view when he declared that the machinery of the Bills must not be destroyed.
