  proclamation  provided  in  the  third  section  of  such  act  of   the
  legislature  of  Massachusetts,  provided,  however, that nothing herein
  contained shall be construed  to  affect  existing  titles  to  property
  corporeal  or incorporeal held under grants heretofore made by either of
  said states, nor to affect existing rights which said states, or  either
  of  them,  or  which  the citizens of either of said states may have, by
  grant, letters patent or prescription irrespective of the boundary  line
  hereby  established, it not being the purpose hereof to define, limit or
  interfere with any such right, rights or privileges  whatever  the  same
  may be.
