The Same, Rules, Book VI. It is held that a son is specifically disinherited in the following words, “Let my son be disinherited”, even if his name is not expressly stated, where the testator has only one son; for where he has several, the opinion is entertained by most authorities, in accordance with the more beneficent interpretation, that none of the sons will be disinherited.

Ulpianus, Rules, Book VI. If, during my lifetime, I should sell my slave, whom I had appointed my heir with the grant of his freedom, to a party who did not have testamentary capacity, and afterwards I should redeem said slave, he can be my heir under the will; nor will the intermediate time during which he was in the hands of another master annul the appointment, because it is certain that he has been mine at both times, namely that of the execution of the will, and that of death. Wherefore, if he had remained in the hands of his other master, the appointment would become void; or if he had been transferred to someone who had testamentary capacity, he would acquire my estate for the latter through entering upon it by his direction. 1If the condition upon which the appointment of an heir was dependent stated that some act was not to be performed, and it was impossible, the person designated will be the heir in accordance with the opinion of all authorities, just as if he had been unconditionally appointed. 2An estate is generally divided into twelve parts, which are included in the appellation as. These parts all have their own names from the uncia to the as, for example, the following: “The sixth, the fourth, the third, five-twelfths, half, seven-twelfths, two-thirds, three-fourths, five-sixths, eleven-twelfths, the as.”
