On display this week in the Lowell House Library are some of the books designed and illustrated by Mr. William A. Dwiggins of Boston, one of the foremost designers of fine books in this country. The most interesting volume is his recently published "Reform of the Currency," which has attracted wide attention and comment. In this book he flays not our fiscal system but the appearance of our bills. At the same time he offers suggestions for redesigning them. Other volumes of note are his Balzae's "Droll Stories," Poes "Tales," a charming little edition in two volumes of Daudet's "Tartarin of Tarascon," Stevenson's "The Strange Case of Dr. Jekyll and Mr. Hyde," and H. G. Wells' "Time Machine," which contains a new introduction by the author.
