PREFACE ix 



for their valuable contributions and aid ; and in the 

 case of Mr. Mackenzie — besides the assistance he 

 has rendered me in the native languages — I am 

 further deeply indebted for his unfailing help and 

 counsel in all matters relating to those tribes and 

 regions with which he is so familiar. 



In other departments of inquiry I am no less 

 indebted to the clear judgment and scientific attain- 

 ments of my friend the Rev. Thomas Hincks ; 

 whilst Mr. H. W. Bates has again proved to me 

 in this edition, as he did in the first, an unfailing 

 source of strength whenever I have applied to 

 him. To Dr. Jentinck of Leyden and the Rev. 

 P. H. Wicksteed I owe my sincere thanks for 

 the light they have thrown on numerous doubtful 

 points of Dutch philology and spelling ; as I do 

 in other branches of knowledge to Professors 

 Mayor, Sayce, and Skeat, Messrs. J. G. Baker, 

 J. O. Waterhouse, E. A. Beck, and F. Jeppe, and 

 in more general matters, to those other friends who 

 have so kindly and generously assisted me. 



A sadder task remains to me in referring to the 

 untimely deaths, first of Professor Rolleston, which 

 occurred shortly before the appearance of the first 

 edition of this book, and (more recently) of Mr. 

 Gilchrist of Ospisdale, whose name is so tenderly 

 and enduringly associated with my brother's memory 

 and all that befell him in South Africa.
