vi PREFACE 



previous to the new regime inaugurated by Sir William 

 Flower. The writer may take this opportunity of 

 stating that these are in no wise intended to convey the 

 slightest reflection on those who had charge of the 

 galleries previous to the new era. Technical museum- 

 installation and display is a comparatively new thing ; 

 and the old plan of arrangement had become obsolete, 

 not for want of attention, but because a more advanced 

 scheme had been developed by gradual evolution, and 

 the adoption of this involved a clean sweep. 



In conclusion, the writer has to express his best 

 thanks to Mr. C. E. Fagan, of the Secretariat of the 

 Natural History Museum, for kindly reading and re- 

 vising the proof sheets.
