_Heraldic Colour pertaining to Ireland._--There occurs in the _Dublin
University Magazine_ for October, 1852, an article entitled "A Night in the
Fine Arts' Court of our National Exhibition," and at the conclusion a
"Note," in which I find the following remarks:--
"This last (the figure of Erin), as described, is purely ideal, but
legitimately brought in, as Hogan's figure of 'Hibernia' occupied a
position in the Fine Arts' Court, and suggested it. It may be as well
to add that Erin is described as wearing a _blue_ mantle, as blue, not
green, is the heraldic colour pertaining to Ireland now."
May I inquire at what time, and under what circumstances, blue was
substituted for the old favourite green?
