Horace Gray, Thompson v. First National Bank of Toledo Ohio…
“ But the question whether the plaintiff was induced to change his position by acts done by the defendant or by his authority is, as in other cases of estoppel in pais, a question of fact for the jury, and not of law for the court. The nature and amount of evidence requisite to satisfy the jury may vary according to circumstances. But the rule of law is always the same: that one who had no knowledge or belief that the defendant was held out as a partner, and did nothing on the faith of such a knowledge or belief, cannot charge him with liability as a partner if he was not a partner in fact. ”
