The error in an instruction given at the instance of plaintiff, in an action for commissions for procuring a purchaser of real estate, authorizing a recovery on a finding that plaintiff was employed to procure a purchaser, and introduced a customer to whom a sale was subsequently made, arising from the failure to require a finding that the broker was the procuring cause of the sale, was not cured by a charge, given at the instance of the defendant, that before judgment could be rendered for plaintiff, he must show that through his services one was induced to purchase the property, since the two instructions were contradictory. Russell v. Poor (Mo. App. '08), 119 S. W. 433.
