«This volume has been compiled chiefly for the benefit of opium-eaters. Its subject is one indeed which might be made alike attractive to medical men who have a fancy for books that are professional only in an accidental way; to general readers who would like to see gathered into a single volume the scattered records of the consequences attendant upon the indulgence of a pernicious habit; and to moralists and philanthropists to whom its sad stories of infirmity and suffering might be suggestive of new themes and new objects upon which to bestow their reflections or their sympathies.»
