Under such circumstances the faults of omission and compression could not be avoided in revising Professor Keane's work, but it is hoped that the copious references which form a prominent feature of the present edition will compensate in some measure for these obvious defects. The main object of the revisers has been to retain as much as possible of the original text wherever it fairly represents current opinion at the present time, but so different is our outlook from that of 1899 that certain sections have had to be entirely rewritten and in many places pages have been suppressed to make room for more important information. In every case where new matter has been inserted references are given to the responsible authorities and the fullest use has been made of direct quotation from the authors cited. Mrs Hingston Quiggin is responsible for the whole work of revision with the exception of Chapter XI, revised by Miss Lilian Whitehouse, while Dr A. C. Haddon has criticized, corrected and supervised the work throughout. A. H. Q. A. C. H. 10 _October_, 1919. CONTENTS CHAP. PAGE I. GENERAL CONSIDERATIONS 1 II.
