tedious and incurable disorder of body or mind, which is not discernible
to the ordinary man, if the purchaser be a physician or trainer, he
shall have no right of restitution; nor shall there be any right of
restitution if the seller has told the truth beforehand to the buyer.
But if a skilled person sells to another who is not skilled, let the
buyer appeal for restitution within six months, except in the case of
epilepsy, and then the appeal may be made within a year. The cause shall
be determined by such physicians as the parties may agree to choose; and
the defendant, if he lose the suit, shall pay double the price at which
he sold. If a private person sell to another private person, he shall
have the right of restitution, and the decision shall be given as
before, but the defendant, if he be cast, shall only pay back the price
of the slave. If a person sells a homicide to another, and they both
know of the fact, let there be no restitution in such a case, but if he
do not know of the fact, there shall be a right of restitution, whenever
the buyer makes the discovery; and the decision shall rest with the five
youngest guardians of the law, and if the decision be that the seller
was cognisant of the fact, he shall purify the house of the purchaser,
according to the law of the interpreters, and shall pay back three times
the purchase-money.

If a man exchanges either money for money, or anything whatever for
anything else, either with or without life, let him give and receive
them genuine and unadulterated, in accordance with the law. And let us
have a prelude about all this sort of roguery, like the preludes of our
other laws. Every man should regard adulteration as of one and the same
class with falsehood and deceit, concerning which the many are too fond
of saying that at proper times and places the practice may often
be right. But they leave the occasion, and the when, and the where,
undefined and unsettled, and from this want of definiteness in their
language they do a great deal of harm to themselves and to others. Now
a legislator ought not to leave the matter undetermined; he ought to
prescribe some limit, either greater or less. Let this be the rule
prescribed: No one shall call the Gods to witness, when he says or does
anything false or deceitful or dishonest, unless he would be the most
hateful of mankind to them. And he is most hateful to them who takes a
false oath, and pays no heed to the Gods; and in th
