[MARCELLUS libro tertio digestorum. ] §45.1.94.prTriticum dare oportere stipulatus est aliquis: facti quaestio est, non iuris.
[MARCELLUS, Digest, Book 3] Someone stipulated that wheat ought to be given: this is a question of fact, not of law.
igitur si de aliquo tritico cogitauerit, id est certi generis certae quantitatis, id habebitur pro expresso: alioquin si, cum destinare genus et modum uellet, non fecit, nihil stipulatus uidetur, igitur ne unum quidem modium.
Therefore, if he had in mind some particular wheat, that is, of a certain kind and of a certain quantity, this will be held as if it had been expressly stated; otherwise, if, although he wished to determine the kind and the quantity, he did not do so, he is deemed to have stipulated for nothing, and therefore not even a single modius.
