FRANCES CALDERON DE LA BARCA, born in Edinburgh, 1804, the daughter of William Inglis. After her father's death she settled in America, where she married the Spanish diplomat, Don Angel Calderon de la Barca. She accompanied him on his various appointments to Mexico, Washington, and finally to Madrid, where she was created Marquesa de Calderon de la Barca by Alfonso XII and died in 1882.
The present work is the result of observations made during a two years' residence in Mexico, by a lady, whose position there made her intimately acquainted with its society, and opened to her the best sources of information in regard to whatever could interest an enlightened foreigner. It consists of letters written to the members of her own family, and, really, not intended originally--however incredible the assertion-for publication.
