“I. It is set forth by the pursuer that the instrument under challenge, in so far as it refers to the first disponee in the tailzie after heirs of the granter's own body, is uniformly and in every instance erased , and the first question which arises is, If this be an erasure in essentialibus? As to that point the Lord Ordinary has no doubt. It is self-evident that the name or legal designation of the party called in a leading place of the destination, is one of the most essential parts of a conveyance, and, therefore, if the deed under reduction had been a conveyance to that party alone, whose right is constituted only by words written uniformly on erasures, it must have been instantly reduced as void and improbative. The analogous case of Keddar, decided in this Court in 1835, ( vide Reports of 6th March, 1835,) and affirmed with costs in the House of Lords within these few weeks, would be decisive of the question. In one respect the erasures in the case of Keddar could hardly be viewed as so essentially affecting the deed as those which occur here; for in Keddar's case the testing clause was so framed as to entitle the defender very plausibly to argue that the word erased had been altered by consent of the granter; but there is no such speciality in the present case.
