stated that it came from Sais. A large portion of this work is devoted
to the visual organs. On the twentieth line of the fifty-fifth page
begins the book on the eyes, which fills eight large pages. We were
formerly compelled to draw from Greek and Roman authors what we knew
about the remedies used for diseases of the eye among the ancient
Egyptians. The portion of the Papyrus Ebers just mentioned is now the
only Egyptian source from whence we can obtain instruction concerning
this important branch of ancient medicine.

All this scarcely seems to have a place in the preface of a historical
romance, and yet it is worthy of mention here; for there is something
almost "providential" in the fact that it was reserved for the author of
"An Egyptian Princess" to bestow the gift of this manuscript upon the
scientific world. Among the characters in the novel the reader will meet
an oculist from Sais, who wrote a book upon the diseases of the visual
organs. The fate of this valuable work exactly agrees with the course of
the narrative. The papyrus scroll of the Sais oculist, which a short
time ago existed only in the imagination of the author and readers of "An
Egyptian Princess," is now an established fact. When I succeeded in
bringing the manuscript home, I felt like the man who had dreamed of a
treasure, and when he went out to ride found it in his path.

A reply to Monsieur Jules Soury's criticism of "An Egyptian Princess" in
the Revue des deux Mondes, Vol. VII, January 1875, might appropriately be
introduced into this preface, but would scarcely be possible without
entering more deeply into the ever-disputed question, which will be
answered elsewhere, whether the historical romance is ever justifiable.
Yet I cannot refrain from informing Monsieur Soury here that "An Egyptian
Princess" detained me from no other work. I wrote it in my sick-room,
before entering upon my academic career, and while composing it, found
