Voltaire_Based_OnTo George Sturgis
New York Hotel
Nice, France. December 27, 1922

If my health doesn’t play me false, I hope to have time for finishing all my half-written works, before the end comes. I shall turn out to have been a prolific writer; and if there should ever be a complete edition of my works it will look like one of those regiments in uniform that stand on the shelves of libraries which are not disturbed except to be dusted. However, I have no hopes of rivalling Voltaire whose complete works in 69 volumes I possess in Paris, having got them second hand in a very nice edition (1793, I think) for 400 francs.
