 If any of our earls or barrens, or others holding of us in chief by night service dies, and at his death his heir be of full age and o' relief, he shall have his inheritance on payment of the old relief. Namely the heir or heirs of an earl, one hundred pounds for a whole earl's barreny, the heir or heirs of a barren, one hundred pounds for a whole barreny, the heir or heirs of a night, one thousand five at most, for a whole night's fee, and he who owes less shall give less according to the ancient usage of fiefs.
