Measurements were taken of the dimensions of the crystals and 

 the specific resistance was computed. The value found was .174 ± 

 .004 ohms/cm. cube, at zero degrees Centigrade. The values of the 

 specific resistance obtained by different authors do not agree. How- 

 ever, this is to be expected where mass tellurium is used. But when 

 crystals are used we should expect agreement. 



From the results obtained it appears that tellurium does not obey 

 the Wiedemann-Franz Law, and that the resistance decreases with
