or in the other way. The deforciant cannot vouch a warrantor, since the assise finds  generally for anyone who has the right to present.1
Of the oath of the jurors in the assise of darrein presentment.
 When the jurors are present and there is no objection that can be raised against them,  as above,2 they must swear in this way: Hear this, O justices, that I shall speak the  truth concerning this assise and of the church (or chapel) of which I have made the  view by order of the lord king, and on no consideration will I neglect etc., as above.  And all the other jurors shall swear as above. When they have taken the oath, they  must hear the nature of the writ and the justice must instruct them, to the extent  that such is permitted, and warn them to take care to speak the truth because of the  absence of the deforciant who, if he were present, could inform them as to much.  After having had discussion and consultation among themselves, when the jurors  come before the justices to speak the truth, they may say on their oath that such a  one, the plaintiff, presented the last parson, who is dead, to the aforesaid church in  time of peace, that is, such a one by name, who last died as parson of the same church,  and that he was admitted on his presentation, or they may say the contrary, that  he did not present him nor any other, but another presented him etc. They may state  all the reasons why the presentation does not belong to the plaintiff which the deforciant  himself could put forward were he present, and show why he does not  deforce him wrongfully, as where after the presentation in question the plaintiff or  his ancestor, after that presentation, gave that advowson [to him], by itself, or the  tenement to which the advowson is appurtenant with all its appurtenances and without  any reservation, in fee, or for life, or for a term, or until provision made, as will  be explained more fully below,3 It is not sufficient for the jurors to say that he or his  ancestor presented4 rightfully, unless they show that the deforciant wrongfully  deforces that presentation. Nor is it sufficient that he wrongfully deforces (though a  finding of that kind may be of benefit to others who have right) unless the jurors show  that it is the plaintiff who is deforced, so that he may take something by the assise,  because all the clauses in the writ may be true, but they must still inquire whether the  deforciant deforces rightfully or wrongfully, and if wrongfully,5 if the plaintiff is  entitled to the plaint. They may say that they have no knowledge at all as to who  presented him who last died parson. If they are unable to say anything certain of  him, recourse must then of necessity be had to the seisin of the parson before him,  so that some certainty
