823 FEDERAL REPORTER. �stance, that of a stock-broker, or a soliciter in a matter fairly within the line of business done by the firm, though the form of the employment, so far as correspondence or personal inter- course with the customer or client is governed, is with one of the partners only, and it is induced by relations of special friendship with or confidence in him, yet it is presumed to be, as a matter of fact, an employment of him as a member of the firm, thus throwing the burden of showing that the employment was really intended to be personal on the firm, if they deny their liability.
