With the exception of the observations by Mr. R. Shelford, mainly on the Land Dayaks and Iban, which are duly noted, all the data on the living were collected by Dr. W. McDougall and myself, either separately or conjointly, and I have to thank him for permitting me to work up the results. Our thanks are due to Dr. Hose, at whose invitation we went to Sarawak, and without whose zeal, knowledge of the country, and wonderful influence over the natives this work could not have been accomplished. Mr. S. H. Ray also assisted us as amanuensis. Most of the figures were tabulated for me by Miss Barbara Friere-Marreco and the remainder by Miss Lilian Whitehouse, who also has greatly assisted me in drawing up this memoir.
