RECENT STATISTICAL THEORIES 747 



Sommerfeld's theory of the Hall effect; 



Houston's extension of Sommerfeld's theory of intrinsic potential 

 difference, including especially an explanation of the Peltier heat 

 arising when current flows between two differently-oriented crystals of 

 a single substance; 



Bloch's use of the new methods of quantum mechanics to make 

 allowance for the influence of the atoms on the conduction-electrons; 



Fermi's application of statistical methods to the problem of deter- 

 mining the distribution of electrons in the individual atom; 



Fuerth's work on the fluctuations in the new statistics. 



The bibliography will indicate other interesting advances in a 

 variety of problems.
