“The whole question resolves in this—1st, Whether the entail could competently be freed from the prohibitions, limitations, and restrictions, and yet remain a valid and effectual disposition of the estate; and 2d, Whether this could competently be done on death-bed. Upon the first point, the Lord Ordinary finds no authority or principle to satisfy him that there is any incompetency in discharging the prohibitions and fetters of a tailzied destination, without injury to the disposition and conveyance in the deed of entail, so that they shall remain valid and effectual as such, and the legal result thereby produced be, that the heirs shall be entitled to take the estate as a fee-simple. And if so, the Lord Ordinary is further of opinion upon the second point, that the power or competency of thus revoking and discharging the prohibitions and restrictions is not impaired by the circumstance of the deed of revocation being executed on death-bed.”
