224 Annual Report of the Council. 



the appointment of Mr. Cockle. A few years of association, 

 however, entirely obliterated any feelings of hostility to 

 the Chief Justice that this event may have originally 

 engendered, and the two Judges became sincere and 

 attached friends. Sir James always paid a very marked 

 deference to the opinion of his learned brother, and the
