[HERMOGENIANUS libro secundo iuris epitomarum. ] §18.6.20.prUenditori si emptor in pretio soluendo moram fecerit, usuras dumtaxat praestabit, non omne omnino, quod uenditor mora non facta consequi potuit, ueluti si negotiator fuit et pretio soluto ex mercibus plus quam ex usuris quaerere potuit.
[HERMOGENIANUS in the second book of Epitomes of Law.] If the buyer should commit default in paying the price to the seller, he shall only pay interest, and not absolutely everything which the seller could have obtained if no default had been made; as, for instance, if the seller was a merchant and, upon the price being paid, could have acquired more profit from goods than from interest.
