Evidence of title under H.E. McCulloch grants

In all actions or suits, wherein it may be necessary for either party to prove title, by virtue of a grant or grants made by the king of Great Britain or Earl Granville to Henry McCulloch, or Henry Eustace McCulloch, it shall be sufficient for such party, in the usual manner, to give evidence of the grant or conveyance from the king of Great Britain or Earl Granville to the said Henry McCulloch, or Henry Eustace McCulloch, and the mesne conveyances thereafter, without giving any evidence of the deed or deeds of release, relinquishment or confirmation of Earl Granville to the said Henry McCulloch, or Henry Eustace McCulloch, or the power or powers of attorney by which the conveyances from the said Henry McCulloch, or Henry Eustace McCulloch, purport to have been made.
