The Governments of Europe
“ Between lies a broad and shifting area, which each may enter, but within which the Imperial authority, in so far as is warranted by the constitution, must be accorded precedence over the authority of a state. "The matters over which the states preserve control," says a great German jurist, "cannot be separated completely from those to which extends the competence of the Empire. The various powers of government are intimately related the one to another. ”
