Advocate will here be used in its widest sense, as applying to all who plead the causes of others in courts of justice, whether they are of the class to which the title is usually applied, whose special business it is to deal with facts, either to elicit them from the witnesses, or to present them with a commentary to the Court or the Jury, or whether they are Of that more numerous class who are peculiarly qualified to deal with questions of law. In common parlance, and perhaps in strictness of definition, the former only is designated by the title of Advocate but in this work both will be intended by the term, and in proper place will be described the difference in the qualifications requi site to each, so that the student may be enabled to form some judgment for which department he is by nature and education best fitted, that he may direct his thoughts and studies accordingly.
