I DESIRE to acknowledge the courtesy of the Master and Fellows of Magdalene College, Cambridge, for having permitted me to reproduce the three illustrations facing pages 212, 228, and 230. These are from MSS. in the Pepysian Library. The Viking anchor and block tackle are taken from Mr. Gabriel Gustafson’s Norges Oldtid, by permission of Messrs. Alb. Cammermeyer’s, Forlag, Kristiania. The two illustrations on pages 123 and 132 are here reproduced by the kind permission of Commendatore Cesare Agosto Levi from his “Navi Venete.” The Viking rowlock and rivet are taken from Du Chaillu’s “Viking Age,” by the courtesy of Mr. John Murray. To all of the above I would wish to return thanks.  
E. Keble Chatterton.
