With regard to the selection of Plates, however, it has been found by experience that unless any special subject or plate is required it will be more satisfactory to the subscriber if he gives the Author GENERAL INSTRUCTIONS as to the CLASS of subjects desired and to leave the SPECIFIC selection to him.

Many of the large Libraries and Art or Science Institutions in America and in Europe have subscribed for, and have now in their possession, a complete series of the seven hundred and eighty-one Plates, the subscription price for which is

Five Hundred Dollars

in the United States,

One Hundred Guineas

in Great Britain for the complete series, in eight full American-Russia leather portfolios, or if bound in eleven volumes, each plate hinged, full American-Russia leather,

Five Hundred and Fifty Dollars

in the United States,

One Hundred and Ten Guineas

in Great Britain; or its equivalent for any city in Central or Western Europe.
