Devil's Pillar

There are preserved at Prague three stones of a pillar which the devil brought from Rome to crush a priest, with whom he had made a compact, and to kill him while he said mass. But St. Peter, says the legend, threw the devil and his pillar into the sea three times in succession, which diversion gave the priest time for repentance. The devil was so chagrined that he broke the pillar and saved himself.

Dextrin

or DEXTRINE, in chemistry, (C6H10O5)n, starch gum, British gum; obtained by the action of boiling dilute sulphuric acid on starch, and afterward neutralizing with chalk; if boiled for a longer time the dextrin is converted into dextrose. Dextrin can also be formed by heating starch to between 170° to 200° C. It is a gummy amorphous as mass, soluble in water, and precipitated by alcohol. It is called dextrin on account of its dextro-rotary action on polarized light. Dextrin is formed in germinating seeds by the action of an azotized substance called diastase. Dextrin is used as a substitute for gum.

Dextrose

grape sugar, dextroglucose, C6H12O or C.HO (OH). Dextrose occurs along with levulose in grapes and other sweet fruits, also in honey and in the urine of diabetic patients. It can be produced by the action of dilute sulphuric acid on cane sugar, starch, cellulose, etc. It can be best obtained by boiling for several hours 50 parts of starch with dilute sulphuric acid (100 parts of water to five parts of H2SO4). The solution is then neutralized with chalk, filtered, boiled with animal charcoal to remove traces of color, and then evaporated carefully to dryness, forming an amorphous mass which contains about 60 per cent. of dextrose, the remainder being chiefly dextrin. Pure dextrose can be obtained by crystallization from alcohol. It turns polarized light to the right, and dissolves lime, baryta, oxide of lead, etc. Dextrose reduces an alkaline solution of cupric sulphate, giving a red precipitate of Cu2O on heating. It reduces ferric salts to ferrous salts. Dextrose tastes much less sweet than ordinary cane sugar. By the action of sodium amalgam on dextrose it is converted into mannite, C6H14O6.
