Philadelphia: Claxton, Remsen & Haffelfinger, 1877. Second printing. From the library of Dr. C.B. Farrar with his bookplate. Tall 8vo., orig. blue cloth stamped in gilt, iv, 185pp. With a frontispiece. Fine.
Brigadier General A.J. Pleasonton, [1808-1894], the officer in charge of Union forces defending the state of Pennsylvania, was a voracious reader. One title in his library, Robert Hunt's Researches on Light, dealt mostly with the action of light on inorganic chemicals and its contribution to the art of photography. Pleasonton, however, was influenced by a chapter on the effect of light on organic materials and set up experiments involving blue glass. Eventually he persuaded himself and countless others of the utility of blue glass for growing larger plants and animals and curing all sorts of physical and mental diseases. Both he and his follower S. Pancoast became so enamored with blue, that they printed their books in blue ink. In 1877, the weekly (at that time) Scientific American put an end to the fad with three articles on "The Blue Glass Deception."
