PREFACE 



OUR object in writing this book has been to bring together in a concise 

 form the fundamental facts and principles of Physiology, primarily 

 with the object of meeting the requirements of the medical student 

 preparing for a pass examination in the subject of Physiology. Con- 

 siderations of space have led us to exclude as far as possible histological 

 details and descriptions of chemical and experimental methods which 

 form part of each student's laboratory course, and for which separate 

 text-books are used. We have also omitted, for the same reason, all 

 matter of purely historical interest. 



In view of the transitional state of anatomical nomenclature, we 

 have, after much consideration, retained the terminology hitherto used 

 in this country, and have inserted the Basle nomenclature in brackets. 



While it is impossible to mention all the sources upon which we 

 have drawn, we wish to acknowledge our especial indebtedness to 

 Professor Starling, not only for permission to use many figures from 

 his Principles of Physiology, but also for advice and information on 

 many points. Our thanks for permission to use figures, which are 

 as far as possible separately acknowledged in the text, are also due to 

 Professor Sir E. A. Schafer (Qiiain's Anatomy and Essentials of Hist- 

 ology), Professor J. N. Langley (Journal of Physiology), Dr M. S. 

 Pembrey (Practical Physiology), J. Barcroft, Esq. (Respiratory Function 

 of the Blood), Dr A. Hertz, Dr Homans, Dr W. E. Hume, Professor R, 

 Howden (Gray's Anatomy), and the Council of the Royal Society. We 

 'must also thank the Publishers and others who have kindly supplied us 

 with blocks, namely, Messrs J. & A. Churchill, Hodder & Stoughton, 

 Macmillan & Co., Ltd., Mr Edwin Arnold, the Cambridge University 

 Press, Messrs Baird & Tatlock, Ltd., and Messrs Hawksley. 



Finally, we are indebted to Miss F. H. Miller for her unwearying 

 efforts in the production of the original illustrations, and to Messrs 

 Longmans, Green & Co. for the great pains they have taken in the 



reproduction of the figures.
