Q. Does any thing ELSE radiate heat, BESIDES

 some measure, but not equally well. 



Q. WHAT things RADIATE heat the NEXT BEST 

 to the sun and fire ? 



A. All dull and dark substances are 

 good radiators of heat ; but all light and 

 polished substances are bad radiators of 

 heat. 



Q. Why does a POLISHED METAL TEA-POT 

 make BETTER TEA than a black earthen, one ? 



A. As polished metal is a very bad 

 radiator of heat, it keeps the water hot 

 much longer ; and the hotter the water 

 is, the better it " draws" the tea.

 good tea ?
