— The negotiation which led to the exchange was entered into about the first of February, 1886. On the twelfth of that month the parties signed a contract by which it was stipulated that one E. J. White, plaintiff’s son-in-law, should make a preliminary examination of the Iowa property, and report the result thereof to plaintiff, who reserved the right either to then terminate the negotiation, or to proceed to make a personal examination of the property and determine therefrom whether he would make the trade. It was also stipulated in case he should determine, after receiving White’s report, to make a personal examination, that the parties
seldom be predicated on the mere expression of an opinion. Clark v. Ralls,
Aeeiemed.
