There is an un-dated divisional title page for New Atlantis. The "Sylva Sylvarum" is a collection of Bacon's scientific experiments and observations in natural history, which were intended for inclusion in his "Instauratio Magna." The work was edited and published posthumously by his friend William Rawley. The appended "New Atlantis" is one of Bacon's most popular works and has served as inspiration for many scientific organizations. "It ranks among the best knowna nd most pleasant of the Utopian writings." -Bernal 305. An amusing ink inscription on rear of title page, dated 1869, states "Finding this book too stupid, I cannot do better than to offer it to my dear niece."
