popsession to be described and often photographed for use in this work ; and, lastly,
he would thank all those critics who with much courtesy have written to him pointing
out various errors and suggesting additions and improvements.
It was at one time thought that a supplement might be added to this final volume containing notices of the painters — unfortunately a considerable number — who have passed away while the book has been in the press, as well as certain memoirs omitted in previous volumes.

The Editor, therefore, can only express the hope that when sufficient material shall have accumulated, he may be privileged to issue a supplementary volume, and with this object in view he will always be grateful for the assistance of his numerous readers, and begs them to be good enough to communicate with him (to the care of the publishers) as to any omissions or errors that they may at any time discover, or any special information they may be able to impart.
