“ When a see is vacant the jurisdiction is exercised by a “special commissary” of the metropolitan. Commissary is also a general military term for an official charged with the duties of supply, transport and finance of an army. In the 17th and 18th centuries the commissaire des guerres, or Kriegskommissär was an important official in continental armies, by whose agency the troops, in their relation to the civil inhabitants, were placed upon semi-political control. ”
