Henry Clay Quote

In all cases where incidental powers are acted upon, the principal and incidental ought to be congenial with each other, and partake of a common nature. The incidental power ought to be strictly subordinate and limited to the end proposed to be obtained by the specified power. In other words, under the name of accomplishing one object which is specified, the power implied ought not to be made to embrace other objects, which are not specified in the constitution.
