Joseph P. Bradley, Holladay v. Kennard — Opinion of the Court
“ Ordinary diligence, like most other human qualifications or characteristics, is a relative term, to be judged of by the nature of the subject to which it is directed. It would not be any want of ordinary care or diligence to intrust the shoeing of a horse to a common blacksmith, but it would be gross negligence to intrust to such a person the cleaning or repair of a watch. ”
