(f to f inch) long, 5 to 9 mm to J inch) broad, bluntlypointed at the base, externally blackish-brown, netted-wrinkled,weighing about .5 gm, inodorous and tasteless, and containing a shriv-eled seed. The pericarp is 1 mm. thick, and consists of three well-defined layers of nearly equal thickness : the blackish-brown resinousepicarp, the yellowish-green mesocarp, and the yellowish brittle endo-.

Soaked in water, the mesocarpswells considerably, and somewhat less the epicarp. Both tissues areformed of thin walled cells ; those of the latter are filled with a brownmass; those of the former colorless or brownish, and surroundingnumerous fibrovascular bundles. The thin walled cells of the testacontain a red brown mass. The endosperm is hard and hornlike,swells rapidly in water, and consists of a peculiar parenchyma, whichbecomes gelatinous by potassa. Iron salts color the contents of the cells of the epicarp blue, butscarcely affect those of the testa. The contents of the latter are solu-ble in alkalies; those of both tissues insoluble in water. The meso-carp contains S]3aringly groups of calcium oxalate crystals, also rem-
