Bibliographic description of the first publication containing this work, quoted from the Danish bibliography H.C. Andersen-Centrets bibliografiske optegnelser:
The two Baronesses
This is the first work Mr. Andersen, the Danish poet, has put forth in an English dress; and, if written in English by his own unassisted efforts, it shows no mean proficiency in the language of this country. [...]
The scene of the romance itself is laid in the author's native country, and though its incidents may appear a little disjointed, and the thread of the narrative rather difficult to unravel, the careful reader will not fail to remark throughout those qualities which have recommended the previous works of M. Andersen to favourable notice. Great sensibility, nice delineation of characters, and an aptitude at description which his poetic feeling has engendered and perfected, are visible in every page.
