             ***
         Thank 
        you to Ron Cosens for sending me a copy of a carte de visite that 
        appears to contradict the details in the table below. 
        
            -  The carte de visit is dated (in ink) 
        March 1865. 
        
            -  The details printed on the back read:

        These are the addresses for Ross & Thomson that have appeared in the 
        trade directories and on the backs of some of my cartes de visite:

        It appears that the 'Ross & Thomson' Partnership came to an end 
        around 1864, with James Ross staying on at the '90 Princes Street' 
        studio until at least 1865 (as well as having a studio in Lothian Road 
        in 1865.
