it was placed on an Imperial basis. The collection of the cases of facial injuries from the British, Canadian, Australian, and New Zealand forces in one hospital under their own medical officers has proved a factor of prime importance in the improvement of methods of treatment.
Major Waldron and Captain Risdon (Canadian Section), Colonel Newland, D.S.O. (Australian Section), and Major Pickeril, O.B.E. (New Zealand Section), and the officers serving with them, joined heartily in friendly rivalry and healthy competition, to the great benefit of these poor mutilés.
Further, with the arrival of American surgeons in 1918 under Colonel Vilray P. Blair, M.R.C.U.S.A., our wounded had call upon surgical, skill from the whole Anglo-Saxon race. Each surgeon had the assistance of one or more colleagues from the New World, to their mutual advantage.
Needless to say, the author realises his indebtedness to the numerous visiting and consulting surgeons who from time to time have encouraged him by their advice.
The knowledge of their interest and good-will has been a most powerful stimulus towards perseverance in times when difficulties appeared insurmountable. He wishes particularly to thank Sir W. Arbuthnot Lane, Sir Francis Farmer, and Sir Frank Colyer, among consultants; and, among his British colleagues, Major G. C. Chubb, Captains C. F. Rumsey, the late E. G. Robertson, F. E. Sprawson, J. L. Aymard, R. Montgomery, H. C. Malleson, and A. L. Fraser in the earlier part of the work, and later Captain T. P. Kilner, T. Jackson, and Majors H. Bedford Russell and J. J. M. Shaw, M.C.
In particular, the stimulus of co-operation with Major Seccombe Hett has considerably advanced the treatment of injuries to the nose; while the pioneer work of Captain King on the jaw has been maintained and further developed by Captain W. Kelsey Fry, M.C., R.A.M.C., Chief Dental Surgeon, who has written a chapter on the use of Prostheses in this work. In this connection the work of Valadier and Kasanjian in France has been of great service in the improvement of the treatment of jaw wounds. I am indebted to the former for many photographs of the original conditions, and to both for the stimulation of their work and for much kindly encouragement.
Among many American colleagues Captain Ferris Smith has shown himself the most constructive critic the author has had the pleasure of knowing. He was of great assistance in the preparation of the early proofs of this work.
Not a small feature in the development of this work is the compilation of case records. The foundation of the graphic method of recording these cases lies to the credit of Professor H. Tonks (Slade Professor), many of whose diagrams and photographs of his remarkable pastel drawings adorn these pages.
