 If acted upon before the law was changed, it might well be that all the powers and privileges originally conferred, in the charter of the Cairo and Fulton Railroad Company, including the exemption in question, would have vested in the new company.But, as it was not accepted and acted upon until a change in the organic law of the state forbade the creation of corporations capable of holding property exempt from taxation, it must be presumed that when the original company entered into the consolidation, it did so in full view of the existing law, and with the intention of forming a new corporation, such as the Constitution and laws of the state at that time permitted.That at least, we must hold to be the legal effect of the transaction.
