readily part with much of the heat communicated to them, 

 and thus occasion a great difference of temperature at the 

 opposite junctions of the thermo-electric elements. These 

 diffusers enable the length of the thermo-electric elements to

be reduced without inconvenience. It will aiso be readily 

 understood that the diffusers, on account of their large radi- 

 ating surface, will emit much heat, and thus render the appa- 

 ratus capable of being used as a source of heat, or as a stove 

 for warming an apartment.
