Death and Bankruptcy are notice to the world of the dissolution of a partnership; but in the case of a voluntary withdrawal of a member from a firm, it is incumbent on the firm to give notice in order that his power to use the firm name may cease, and it is incumbent on the retiring partner to give notice in order that his liabilities as a partner may cease; but actual notice, no matter by whom or how given, is sufficient. It is usual to inform the public generally by notice in paper, and former patrons by mail, as the law requires proof of actual notice to the latter.
