duced by the Ii3drolysis of the latter. A con- tinuation of the hydrolytic action results in the formation of sugars. The principal dextrins are: erytliro-dextrin, achroudexlrin, and malto- dextrin, all of which have the same relative com- position as starch— (CoH.oOjln ; their molecular weights, liowever, are unknown. -Vchroijdextriii may be jirepared by the i>rotonj;ed action of saliva or pancreatic juice on stardi paste; when the solution ceases to be coUired by the addition of iodine, that is to say, when all the starch has been transformed, the solution is concen- trated by evaporation and precipitated with alcohol. The substance thus obtained is com- pletely freed from maltose by warming with mercuric cyanide and caustic soda and may be further purified by dissolving in water and reprecipitating with alcohol.

Dextrin (British gum or starch gum) is often ^ ^' used as a substitute for gum arable in the processes of calico-printing, and for stitlening different goods: it is also applied to the back of postage stamps. Its value as a substitute for gum consists in its being more flexible and less brittle, when dry, than that substance. For com- mercial purposes it is prepared on a large scale either by moistening potato-starch with weak nitric acid, then drying and lieating to 110° C, cr by simply heating the starch to about 2501 C. When thus prepared, dextrin contains consider- able amounts of dextrose and unaltered starch.

DHUN'CHEE (F-.tni.) . f^esbania nculrata. A plant of the natural order Leguminos.T. The dhunchec is an annual herbaceous plant, much cultivated in India upon account of its fibre; it has an erect, sparinglv branched stem, G to 10 feet high. It is a plant of rapid growth, and succeeds best in low and wet soils. Its fibre is coar-ser than hemp, except when it is cut at a ver.v early period of its growth, is durable in water, but contracts considerably when wetted. It is steeped and prepared very much like Sunn (q.v.). It is native to the Malabar coast and
