one, let the enrolment of the simple essoin be made as follows: Such a one [essoined  himself] against such a one with respect to such a plea by such a one. [Provided  that mention first be made in the margin of the name of the county.]1 If  there is only one demandant and one tenant, each may essoin himself once, together  and on the same day or successively, first one and then the other, if the demandant  so wishes. The reason why it lies for the demandant is because here nothing is permitted  the tenant which is not allowed the demandant.2 Let the enrolment with  respect to the demandant, when the tenant has essoined himself, be made as  follows: And the same [demandant] against [the tenant] with respect to the same  by such a one. Thus if both essoin themselves together and on the same day. If  successively, and the tenant has essoined himself first and the demandant appears  and receives the same day in court, he may essoin himself on the second day, if he  wishes, and conversely, if the demandant has essoined himself on the first day and  the tenant appears and receives the same day, he may essoin himself on the second  day, and so any number of times, as long as the demandant has been essoined. If  there are several parceners, tenants holding in common or separately, each will have  his own essoin and essoiner, provided that if they hold in common they may all  essoin themselves together on the same day, or successively, one or several, until  each, if he so wishes, has had a single essoin before he appears, and no more; let the  enrolment then be made thus: Such a one [the tenant] against such a one [the demandant]  with respect to such a plea by such a one. The same may be said of all the  other tenants who essoin themselves; the same day will be given to all those who  are present, and against the absent proceedings must be taken to default. If there  are several tenants who hold individually each will have his essoin but not successively,  as above.3 If one or several tenants ought to essoin themselves against  several demandants, mention need not be made of all the demandants, only of one  and of the others named in the writ. And let the same be done for one demandant  or several against several tenants.4
If a warrantor is vouched.
 If a warrantor, one or several, is vouched by one tenant or several, each of them  will have a single essoin if he wishes, together or separately, both the tenant who  vouched and the warrantor vouched, one or several. Hence when the warrantor  essoins himself let the enrolment be made as follows: Such a one whom such a one  (or such persons) vouched to warranty against such a one (or such persons)
