[MARCELLUS libro singulari responsorum. ] §13.5.24.prTitius Seio epistulam emisit in haec uerba: 'Remanserunt apud me quinquaginta ex credito tuo ex contractu pupillorum meorum, quos tibi reddere debebo idibus Maiis probos: quod si ad diem supra scriptum non dedero, tunc dare debebo usuras tot.
[MARCELLUS, from the single book of Responses.] Titius sent a letter to Seius in these words: 'Fifty of your credit from the contract of my wards have remained with me, which I shall be obliged to return to you in good condition on the Ides of May; but if I do not pay them by the above-written day, then I shall be obliged to pay so much interest.' I ask whether Lucius Titius, by this security, succeeded to the place of the wards as debtor.
' quaero, an Lucius Titius in locum pupillorum hac cautione reus successerit. Marcellus respondit, si intercessisset stipulatio, successisse.
Marcellus replied that, if a stipulation had intervened, he did succeed.
item quaero, an, si non successisset, de constituta teneatur.
Likewise, I ask whether, if he did not succeed, he is liable under the action on promised money.
Marcellus respondit in sortem teneri: est enim humanior et utilior ista interpretatio.
Marcellus replied that he is liable for the principal sum; for that interpretation is more humane and more useful.
