And if in any other manner or in any other place there be an exchange of one thing for another, and the seller give credit to the man who buys from him, he must do this on the understanding that the law gives no protection in cases of things sold not in accordance with these regulations.

Again, as to contributions, any man who likes may go about collecting contributions as a friend among friends, but if any difference arises about the collection, he is to act on the understanding that the law gives no protection in such cases.

He who sells anything above the value of fifty drachmas shall be required to remain in the city for ten days, and the purchaser shall be informed of the house of the seller, with a view to the sort of charges which are apt to arise in such cases, and the restitutions which the law allows.

And let legal restitution be on this wise: If a man sells a slave who is in a consumption, or who has the disease of the stone, or of strangury, or epilepsy, or some other 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.
