But, as this conceit ariſing from the unskilfulneſſe of Antiquitie, is of the better ſort of ingenuous Scots rejected: […]

   Thus, firſt Traditions were a proof alone; / Cou’d we be certain ſuch they were ſo known: / But ſince ſome Flaws in long deſcent may be, / They make not Truth but Probability.
