as is explained more fully elsewhere, [as above [in the portion] on the assise of novel  disseisin.]1[Fee is also used in another sense, from the point of view of one who  enfeoffs another, what one holds of another, as where one says such a one holds so  many fees of me by knight service.] It may be drawn from what has been said that  one may be seised of land or a rent in his demesne as of fee and as of free tenement, or  only as of fee and not in demesne, or only as of a free tenement, in demesne but not in  fee, as may be said of those who hold only for life in whatever way. And so one may be  seised as of fee and of free tenement with respect to the property and in demesne,  and another as to none of these but only as to the usufruct, as a farmer or fructuary  who holds for a fixed term of years. It says as of fee, so that as (ut) may stand for  as though (quasi) and denote likeness, or for as [and] denote the very truth: the  very truth, as may be said of those who have rightful title and a rightful causa  possidendi [acquired] from those who have the right to bestow them;2 for as though,  as may be said of those who enter without a causa and without rightful title on their  own authority,3<as4 a younger brother or sister, an older being excluded> or5 by a  gift made by a non-lord. Also if [they enter under] a condition, so that their titles6  depend on the snares of fortune, as where7 a gift is made to a bastard and his heirs  and when he has no heir of his body his bastard brother8 enters, marries a wife and  has heirs of his body. If such persons die in seisin they die seised in their demesne as  of fee; there as (ut) is taken to mean as though.
The writ says on the day he died.
 9The writ also contains the words on the day he died or on the day he assumed the  habit of religion, [or] on the day he undertook the journey of pilgrimage on which he  died. Hence we must see how the word day is to be taken. For there is a solar day  and a lunar day, according as God divided light from darkness, [and] from these two  a single day is formed called the artificial day, made up of the day preceding and the  night following,10 which consists of twenty-four hours. An hour is made up of forty  moments. The artificial day is divided into four parts. One begins at dusk and ends at  midnight; the second begins at midnight and ends at dawn, the third begins at dawn  and ends at midday, and the fourth begins at midday and ends at night. Each part  contains six hours. Hence whether one dies on a solar or a lunar day he dies on the  same artificial day, which is reckoned as one day. Hence no matter at what hour of  that
