qualities that were more than once put to the test during our cruise. Before launching into the description of the expedition, I wish to record here my deep sense of obligation to the gentlemen who kindly aided in the production of this Work by contributing chapters of valuable information. In the first place my thanks are due to the Rev. James Chalmers, who kindly continued the thread of the narrative, and brought it to a conclusion, when I was obliged to leave the expedition at Samarai (Dinner Island) about a month before the lamented death of Sir Peter Scratchley. I am also greatly indebted for his interesting paper on "The Manners and customs of the Papuans." On that subject no better source of information than him could be found. To Mr. G. S. Fort I offer my best thanks for presenting me with his Official Report of the Expedition. The same recognition is due to Sir Edward Strickland, the President of the Royal Geographical Society of Australasia, for the permission to embody in my journal the interesting account of the "Bonito" Expedition, undertaken under the auspices of the Royal Geographical Society almost simultaneously with ours. My appeal to Mr. Edelfeld, now exploring in Motu Motu, met with a ready response from that gentleman in the shape of travelling experiences in the neighbourhood of Mount Yule. Last, but not least, I have to thank my learned countryman and friend. Sir Ferdinand Baron Von Müller, the eminent Botanist, for the promise of a valuable essay from his pen, although, unhappily, the pressure of departmental work on his hands is at present so severe that his contribution cannot be ready for this, the first edition of my book; and I cannot conclude without acknowledging my indebtedness to Commander H. Field, of H. M. Surveying Schooner "Dart," and to his able officers, Lieutenants Messum and Dawson, not forgetting Dr. Luther, who, with their uniform kindness and courtesy, made my return journey on board that vessel a perfect pleasure trip.
