From A Bibliography of Alexandre Dumas père by Frank Wild Reed: A graphic description of the treatment of the insane by a Dr. Miraglia. From internal evidence it was evidently written after 1860.
It is now appended to the standard edition of "Jacques Ortis," in the Calmann-Lévy series. (See page 110.)
In Le Vasseur's "Alexandre Dumas Illustré" it forms part of Vol. XVI.
