In any Case described in the preceding Section, the Registrar may, at the Request of the Parties or at his own Discretion, refer in the Record of Title to the Deed, Will, or other Instrument for the Estates and Interests of the Parties, instead of setting out or describing the same: Provided always, that in every Case in which such Deed, Will, or other Instrument shall be so referred to, a Copy thereof (which shall be verified and printed in the Manner hereinafter directed with respect to Deeds or Instruments conveying, mortgaging, or charging the Estate or Interest of any Proprietor on the Register,) shall be delivered to the Registrar by the Parties applying for Registration, and shall be preserved in the Registry; and for the Purposes of any subsequent Sale, Mortgage, or Contract for valuable Consideration by any Person appearing thereby to have any Estate or Interest in the Land to which the Record of Title so made up shall relate, such Copy shall be conclusive Evidence of the Contents of the said Deed, without the Production of the Original thereof.
