What in history is a recommendation would here have been a drawback; the whole of this small volume is true, but not true in the sense required-for a "Biographical Dictionary." I have said several things with the intent to raise a smile, and, if such a thing had been compatible with custom, I might have used the expression _cum grano salis_ as a marginal note in many cases. I have been obliged to be very careful in what I wrote. Many of the persons to whom I refer may be still alive; and those who are not accustomed to find themselves in print have a sort of horror of publicity. I have, therefore, altered several proper names. In other cases, by means of a slight transposition of date and place, I have rendered identification impossible. The story of "the Flax-crusher" is absolutely true, with the exception that the name of the manor-house is a fictitious one. With regard to "Good Master Système," I have been furnished by M. Duportal du Godasmeur with further details which do not confirm certain ideas entertained by my mother as to the mystery in which this aged recluse enveloped his existence. I have, however, made no change in the body of the work, thinking that it would be better to leave M. Duportal to publish the true story, known only to himself, of this enigmatic character.
