MATERIA MEDICA OF THE ANCIENT CHINESE. 5387 
T‘ao Huna-xine :—The ancients say that the hu p‘o is the 
resin of the fir tree, which, being embedded in the soil during 
a thousand years, turns into amber. When burned it emits an 
odour like that of resin. It sometimes incloses insects. An 
imitation of the hu p‘o is produced by boiling hen’s-eggs 
with fish-roe. The genuine hu p‘o, when rubbed between the 
hands till it becomes hot, will attract straw. Now all the hu 
p‘o in China is brought from foreign countries,
