Acceding to the wish of my Publishers that the following pages should be included in a certain well-known series, I have termed them "Chats on Old Miniatures," but confess that I consider the title somewhat of a misnomer, inasmuch as I have been accustomed to regard "a chat" as a conversation between two or more persons interested in a given subject; whereas in this little volume it is obvious that I have done all the talking. In the interval which has elapsed since my larger works appeared the most important event in connection with the subject of Miniatures is, in my opinion, the Exhibition of Works of Art of the Eighteenth Century at the French National Library in 1906. The concluding chapter of this book gives the impressions afforded by that extremely interesting and instructive Exhibition. In the hope that they will be of use to the general reader, I have amplified my references to the public collections of Miniatures in this country, especially those at Hertford House and the Jones Collection, so rich in the works of Petitot. Miss E. M. Foster has been of much service in revising the proofs and passing this work through the press. I have only to add one word, and that relates to the illustrations. I am fortunate in being able to put before my readers so large a selection of choice examples of the art of miniature painting. This I owe to the generosity of the owners of the originals, to whom I desire once again to express my indebtedness and thanks.
