Edmond then resolved to try Jacopo, and offered him in return for his attention a share of his prize-money, but Jacopo refused it indignantly.
As a result of the sympathetic devotion which Jacopo had from the first bestowed on Edmond, the latter was moved to a certain degree of affection.

But this sufficed for Jacopo, who instinctively felt that Edmond had a right to superiority of position--a superiority which Edmond had concealed from all others.
