x PREFACE. 
Minister of Education, and Mr. G. Hogben, M.A., the Inspector- 
General of Schools. My thanks are also due to the Council of the 
Auckland Institute and Museum for kindly allowing me to engage a 
substitute to perform a portion of my duties at the Museum during 
the progress of the work. Finally, I have to express my obligations 
to the Government Printer for the assiduous care with which he has 
attended to the passage of the work through the press. 
Auckland, January, 1906.
