its audacity of shadow is in perfect harmony with the
more roughly picturesque treatment necessary in coins. For the rendering
of all such frank relief, and for the better explanation of forms
disturbed by the luster of metal or polished stone, the method employed
in the plates of this volume will be found, I believe, satisfactory.
Casts are first taken from the coins, in white plaster; these are
photographed, and the photograph printed by the autotype process. Plate
XII. is exceptional, being a pure mezzotint engraving of the old school,
excellently carried through by my assistant, Mr. Allen, who was taught,
as a personal favor to myself, by my friend, and Turner's fellow-worker,
Thomas Lupton. Plate IV. was intended to be a photograph from the superb
vase in the British Museum, No. 564 in Mr. Newton's Catalogue; but its
variety of color defied photography, and after the sheets had gone to
press I was compelled to reduce Le Normand's plate of it, which is
unsatisfactory, but answers my immediate purpose.

The enlarged photographs for use in the Lecture Room were made for me
with most successful skill by Sergeant Spackman, of South Kensington;
and the help throughout rendered to me by Mr. Burgess is acknowledged in
the course of the Lectures; though with thanks which must remain
inadequate lest they should become tedious; for Mr. Burgess drew the
subjects of Plates III., X., and XIII.; and drew and engraved every
wood-cut in the book.

[4] A pamphlet by the Earl of Southesk, 'Britain's Art Paradise'
(Edmonston and Douglas, Edinburgh), contains an entirely admirable
criticism of the most faultful pictures of the 1871 Exhibition. It is to
be regretted that Lord Southesk speaks only to condemn; but indeed, in
my own three days' review of the rooms, I found nothing deserving of
notice otherwise, except Mr. Hook's always pleasant sketches from
fisher-life, and Mr. Pettie's graceful and powerful, though too slightly
painted, study from Henry IV.

OF THE DIVISION OF ARTS.

_November, 1870._

1. If, as is commonly believed, the subject of study which it is my
special function to bring before you had no relation to the great
interests of mankind, I should have less courage in asking for your
attention to-day, than when I first addressed you; though, even then, I
did not do so w
