Quod Deus Opt. Max. bene vertat: Ex decreto et authoritate amplissimi Iurisconsultorum Ordinis in inclyta & celeberrima Basiliensium Academia, pro insigniis & privilegiis Doctoralibus in U.I. consequendis, De Successionibus ab Intestato & cognationis gradibus, eorumque computatione, subsequentes Conclusiones

XV.

That is settled, that the right of succeeding from the first line, which we said obtains among children, also has a place among posthumous children, even if they were born after the womb was opened; provided they are perfect births and legitimate sons.

XVI.

It is proven by the calculation of many that a perfect birth is born in the seventh month. And therefore, he who is born from a lawful marriage in the seventh month is to be believed to be a legitimate son; which also obtains even if he was born at the beginning of the seventh month, or on the one hundred and eighty-second day.

XVII.

Those who come forth in the eighth month are imperfect and not viable; and this is thought to be ascribed to the secret reason and power of the Pythagorean number. If, however, it happens that such a birth is viable and survives, he will not improperly be put in the place of legitimate ones.

XVIII.

In a similar way, it is believed that legitimate children are born in the ninth, tenth, and eleventh months from the day of conception. But yet, one born after ten months from the father's death is not admitted to the lawful inheritance; just as neither is he who comes forth at the end of the eleventh month from the father's death. There are also those who think a legitimate birth is sometimes born in the twelfth, thirteenth, and fourteenth months. But these seem to be beyond belief.

XIX.

They are not children who are born contrary to the form of the human race, in a reversed manner; for instance, if a woman has given birth to something monstrous or prodigious. We decree, however, that it profits the mother in the Lex Papia referring to the Lex Julia et Papia, regulating marriage and inheritance. And so much for natural and legitimate children together.

XX.

As far as it concerns legitimate or adopted children only, it is constant that they, if they have been adopted by a stranger, succeed to both the natural father and the adoptive father; but no lawful rights referring to the portion of the estate reserved for legitimate heirs accrue to them for the family of the adoptive father, nor does it in turn have any communion with them.
