Class 1.—Beal cubebs, ia. those showing both macroscopically and microscopically the features of piper-cubebs, producing, if brought into. touch with concentrated sulphuric acid, the well-known red colouring. 

Class 3.—Not resembling real cubebs at all— without tail and showing a totally irregular microscopic figure—colouring yellow with concentrated sulphuric acid. 

Class 4.—Much resembling the real cubebs, but larger and with a different design of the net-work. With concentrated sulphuric acid colourii yellow. 

In order to check the assortment, 100 fruits of the No. 1 class have been treated with concentrated sulphuric acid one by one it then appeared that 98 gave a red and 2 a yellow colouring. These two prov to belong to the No. 2 class, and have been taken out, so that at last it could be accepted that the Class No. 1 consisted of real cubebs exclusively.
