' Miller developed a system of crystallography which was far more simple, symmetrical, and adapted to mathe- 

 matical calculations than any which has yet been devised. Miller's system was published in 1839 ; it quickly obtained 

 favour, and has more than maintained its ground with mineralogists.' Prof. Bonney, pr., F.E.S. 



' His system gave expressions adapted for working all the problems that a crystal can present, and it gave them in a 

 form that appealed at once to the sense of symmetry and appropriateness of the mathematician . . . He thus placed 

 the keystone into the arch of the science of crystallography.' Prof. Story- Maskelyne, F.R.S.
