the plant which affords the ad-tringent, earthy-looking, mas- 
ticatory and tanning substance called Gambir or Terra 
japonica. This is the Rf fk ZF pin lang kao (betel-nut extract) 
of the Chinese. See Ronpor, Commerce d’Export de la 
Chine, p. 198; Witttams, Chin. Comm, Guide, p. 92; 
P. Suir, 100 [Pale Catechu of Commerce]. This drug has 
frequently been confounded with another drug—very similar 
in composition but widely diverse in botanical origin—the 
Cutch or Catechu, the extract of the wood of Acacia Catechu, 
Willd., which in Chinese is Ki 38 rh ch‘a. See Ronvor, L.c., 
and P. Surra, 55, sub Catechu. The 2. [VII, 15], which 
includes this foreign drug among the earths, calls it B 2 ye 
wu tie ni or F¥% GR AE hai rh ch‘a [meaning “ infants’ tea.” 
But as the Bengal name of the drug is khaiar, this name may 
perhaps be rendered by the above Chinese characters]. The 
Chinesé also, it seems, sometimes confound Gamlir and 
Catechu,
