In furtherance of my object, I have laid under contribution a large number of authorities, and I cannot omit to acknowledge my obligations to the standard works of Meyrick, Hewitt, Demmin, Lacombe and Clephan, to the writings of Baron Davillier and Don Juan Riaño, to the Iconografia Española of Don V. Carderera, and to Dr. Wendelin Boheim, of the Imperial Armoury, Vienna. I also desire to render a special tribute of thanks to Mr. E. B. d’Auvergne, who placed his expert knowledge at my service, and has rendered me invaluable assistance in my endeavours to make this compilation both accurate and complete. The value of a book of this kind must, I recognise, depend in a large measure upon the selection of the illustrations and the excellence of their reproduction. In this matter I have been greatly helped by Señor Don Lacoste, and Messrs. Hauser y Menet, whose photographs, other than those taken by myself, are, with their permission, reproduced here. A. F.
