organisation or arrangement of the positions, shapes, sizes, orientations 
and motions of electrons, atoms, ions, and molecules? To this oft-put 
question the answer of physico-chemicai science is still in the affirma-

‘law of complexity.’ 
Probably future progress will depend more on the investigation of 
the special nature, situation, and action of individuals than on the 
statistical thermodynamic treatment of the average behaviour of the 
“ crowd.’
