[On this matter may be found in the roll of Hilary term in the seventh year of king  Henry on the morrow of the Purification, [the case] between Vitalis Engayngne and  a certain de Ferclis concerning the advowson of the church of Coton.1 And to the  same intent [in the roll] of Michaelmas term in the seventh and the beginning of the  eighth years of the same king, [the case] of the same Vitalis.]2 unless the essoiners  show, by the testimony and record of the constable, that they cast the essoin at the  Tower, or if the essoinee comes on the first day of the suit and disavows the essoiners,  which he may do at any time before3 the essoin of bed-sickness is cast.  When the justices are not resident in the Bench on the day given, the essoin must  always be cast at the Tower. And in the same way in the county court, it must be  cast at the castle.
In whose person an essoin of bed-sickness does not lie.
 Let us see in whose person an essoin of bed-sickness does not lie, though suit is  brought by the writs mentioned above. It will never lie in the person of the demandant,  though in such pleas an essoin of difficulty in coming lies for him. Nor in  the person of an attorney, if the tenant has appointed an attorney, one or several,  because though the attorney is languid and essoins himself de facto of bed-sickness,  he can no4 more send a responsalis than he can appoint an attorney,5 though  sometimes, since no essoin lies for him, he may send a messenger to excuse himself6  up to the fourth day, because of some supervening impediment, as where he is held  in chains or hindered by enemies or adversaries.7 But what if he is languid? He  ought to be excused in the same way, but only up to the fourth day. For who is  more constrained by chains than he who is languid and gravely ill? The essoin  will never lie in the person of a warrantor except after he has appeared in court and  has warranted, since he is thus made the dominus of the suit.8 Nor is an essoin of  bed-sickness of advantage to an essoinee, so as to prevent proceedings to default  from being taken against one who has so essoined himself, who lies outside the  power of the lord king where his writs and returns do not run, whether that is  within the realm or without. Though at first sight the essoin lies, it cannot be investigated  because of that deficiency, 9<as [in the roll] of Michaelmas term in the  sixth [and the beginning of the seventh years] of king Henry among the essoins in  the county of Suffolk, [the case] of Alan de Sancto Georgio.>10 Nor does it lie in the  person of anyone in a plea where one once has languor,11 whether he is the  principal tenant
