Bark in thick, woody, long, straight pieces, flattened—with 
_ asmooth whitish coat, under which the vessels are filled 
with an acrid resin, of a reddish hue; the inside of the 
bark is pale red, or flesh-coloured; taste at first mawkish, 
afterwards acrid and nauseous. It yields both to water 
and spirit, a high-coloured astringent tincture, without any 
bitterness. May be used externally, but seems to haye _ 
but little febrifuge virtue.
