Description.-—Commercial Dikamali occurs in the form 
of irregular flat cakes, of a dull olive green colour, more or — 
less mixed with bark, sticks, and the leaf-buds of the plant.

buds, is transparent and of a bright golden yellow ; it dissolves 
rapidly in rectified spirit, forming a solution of the colour of 
pale sherry, which, when poured into water, forms a delica 
primrose-coloured emulsion. This after standing for 24 hour: s
