These 10 listings are so strange that each appears in only one of the 7 encyclopedias we compared. They include such classics as Damo, Damodar, Damon.

Damo

A daughter of Pythagoras and Theano, to whom Pythagoras entrusted his writings, and forbade her to give them to anyone. This command she strictly observed, although she was in extreme poverty and received many requests to sell them.

Damodar

a river of Bengal, which after a S. E. course, falls into the Hugli, just above the James and Mary Sands. A little below the mouth of its chief tributary, the Barákhar, which it receives from the N., the Damodar becomes navigable. The valleys of these two streams contain the coal-fields which produce about four-fifths of the whole amount of coal mined in British India. Length about 350 miles.

Damon

a Pythagorean philosopher, memorable for his friendship with Pythias, or Phintias. Dionysius of Syracuse having condemned Damon to death, he obtained leave of absence to go home and settle his affairs, Pythias pledging himself to endure the punishment in his stead if he did not return at the appointed time. Damon was punctual; and this instance of friendship so pleased the king, that he pardoned him, and begged, but in vain, to be admitted to their friendship.

Damon and Pythias

or Phintias, two noble citizens of Syracuse, noted for their supreme friendship. Phintias, having incurred the displeasure of the tryant Dionysius, was condemned to die. He begged to be allowed to go home to put his affairs in order. This was agreed to, Damon taking his place in prison. In some way Phintias was delayed. In spite of the jeers of the populace Damon defended his friend's absence with the utmost confidence in his fidelity. Phintias arrived just as Damon was being led out to die in his place. He cast himself into his friend's arms, demanding the latter's instant release and his own execution. Each begged to die for the other. The tryant was so affected by this constancy that he set them both free, and asked to become a third in their fellowship. The friendship of these two has been the subject of many an allusion and the theme of the drama in more than one language.

Damper

A very useful and profitable device in a foundry oven, when intelligently managed. A right knowledge of its use saves both time and money to the founder. Frequently none are employed; and not unfrequently, at places where dampers were originally intended, they have been allowed to lapse into desuetude through sheer and unwarrantable neglect. Let a good-sized chimney, controlled by a full damper, be placed if possible central with the oven at the roof, and one on each side, diagonally, at the bottom, with these. Careful attention will discover in what manner to best rid the oven of steam, at the same time losing no heat. By constant application to find a satisfactory solution of the above problem, ovens with absolutely no record may easily have their value increased a hundredfold. See OVENS.

Dampier (WILLIAM dam'p r an English)

WILLIAM (dam'pēr), an English navigator; born in East Coker, Somersetshire, in 1652; became a mariner at an early age. During many years of active service in privateers and trading-vessels, he several times visited the South seas; and the results of his observations were given to the public in a work entitled "A Voyage Round the World," which for accuracy and interest, as well as for professional knowledge, possesses considerable merit. He died about 1715.

Dampness

The requisite degree of dampness in moulding-sand is a matter of great importance to the moulder. If too moist, steam is generated by the hot metal quicker than the vents will allow it to escape, and scabs will inevitably ensue. If not damp enough, it lacks consistency and fails to preserve its shape in the mould, being easily disturbed during the ordinary operations of moulding, and yielding too readily to the abrading action of the molten metal. See VENTING; SCABBED CASTINGS.

Damps

a name given to certain poisonous gases formed in mines. Miners distinguish two kinds--choke damp and fire damp . Choke damp is composed largely of carbonic acid gas, and is found in the lowest levels. It will extinguish the flame of a candle. No one can live in it for a long time. Fire damp also contains carbon, combined with hydrogen and mixed with atmospheric air. It explodes in contact with a flame. Miners going to their work with lighted candles or lamps not infrequently run into fire damp before they are aware of it. Violent explosions result in the death of many men. As early as 1815 Sir Humphry Davy invented a safety lamp which consisted essentially of a cylinder of wire gauze surrounding the flame. Fire damp passes through the meshes of the gauze and burns within with a feeble blue flame. The flame of the lamp cannot pass out through the gauze without being cooled to such a degree that it cannot ignite the dangerous gases. See Davy ; Sir Humphry; Safety Lamp
