Stephen Johnson Field,
United States v. Chouteau — Opinion of the Court
“ It is certainly one way of defending against the charge of a wrongful act for which damages are sought, to show that, notwithstanding the wrong committed, the damages resulted from other causes, however objectionable a pleading might be with averments to that effect instead of a distinct traverse of the allegations of the complaint. If, for example, a party should charge another with inflicting upon his person a wound by which he lost an arm, it would be a good defence to show that the loss resulted from unskilful medical treatment or neglect and not from the wound inflicted. ”
