Epigraph
Sunt geminæ Somni portæ: quarum altera fertur
Cornea, qua veris facilis datur exitus umbris:
Altera candenti perfecta nitens elephanto:
Sed falsa ad cælum mittunt insomnia manes.
Virgil, Æn. VI.
Note
After this novel was commenced in Chambers’s Journal it was discovered that the title had already been used by the late Mr. Mortimer Collins, for a novel published in the year 1865. The Author communicated with Mr. Collins’s representatives, and has to thank them for making no opposition to the use of this title.
