Rufus Wheeler Peckham, Memphis City Bank v. Tennessee…
“ It was not, properly speaking, a mere act increasing the powers of the corporation, so that such corporation could perform other acts of a nature similar to those which it was already authorized to perform by its original charter. It was not an increase, but it was a change, of powers, to the extent that those granted by the act of 1887 were of a totally different character and nature. An insurance corporation differs radically from a banking corporation, and the powers given to one cannot be exercised by the other without some authority granted by the state through its legislature. ”
