Palmistry, or Chiromancy. Art of divination by examining lines in the palm of the hand; said to have come from India. It is to be distinguished from chirognomy, which deals with

the supposed indications of the general shape of the hands. The principal lines of the palm are designated respectively as those of Life, the Head, the Heart, Saturn or Fate, the Liver, and Sun or Fortune. The prominences or depressions at the base of each finger also are regarded as highly significant, and are called by the names of the planets: Jupiter, Saturn, Mars, Mercury, Venus, Apollo (the Sun), and the Moon. These are referred to the tastes or passions. The lines are interpreted according to their depth, color, and length, and their relations to the prominences or Mounts. The lines of the wrist, called Rascettes, or bracelets, are believed to indicate the duration of life, each line representing thirty years.

lets of lire. Qf lne fjrsfc flnger indicate skill

and thrift; at the first joint of the thumb wealth, and on the palm below the thumb wisdom. Lines on the palm below the little flnger indicate children, as many as there are lines; the lines below these refer to success in matrimony. If the fine lines on the palmar surface of the middle finger are in the form of a circular spiral, it is a sign of skill in handwriting. These indications refer to the left hand; another series is supposed to apply to the right. The Line of Life receives the same name as in Europe, and is also known as the Line of Earth or Mother, while that of the Heart is thought to represent Heaven or Father, and that of Head, Man, or the individual himself. The relations of these lines, forming the cosmical Trinity, are believed to be of the highest importance. See Chiromancy.

Pambour's Theorem. "In a heat engine, moving with a uniform periodical motion, the mean effective pressure of the fluid is equal to the total resistance per unit of area of piston."

[blocks in formation]

Where the resistance is known, the mean velocity of the piston

r'hW

of such an engine will be found from the formula: Ns— —.

rpA

In this, N — strokes using steam per min.; s — stroke length; r1 — apparent ratio of expansion, and r — the real ratio when clearances in the cylinder are allowed for; h — the available heat of combustion in foot-lbs. for one lb. of coal; W — the lbs. of coal burned per minute; A —area of piston in square inches, and p = pressure equivalent to the expenditure of heat, r and p have to be calculated from other formulae; the others are matters of observation. The principle was first applied by Count de Pambour in his Theory of the Steam Engine and On Locomotives.

Pangenesis. Theory of Darwin that the generative cells are collectors of spores (gemmules) thrown off from all the cells of the body throughout life. During development the gemmules produce their corresponding tissues again. Prof. W. K. Brooks has suggested certain modifications: 1. The generative cells are direct descendants from the egg which produced the body of the parent, and therefore the gemmules of each egg can develop a child resembling the parent. 2. New gemmules are received especially from tissues that are subjected to strain through ill adaptation to environment. 3. These gemmules hybridize the old gemmules of like kind, and so the resulting tissue receives an impulse to vary. 4. The male gametes are specially differentiated to receive new gemmules; hence the male leads in progress. Thus variations are produced when and where they are needed, and the very long period required for evolution, according to Darwin's theory, may be greatly shortened. See Natural Selection and La

Paper. Manufactured from Papyrus (q.v.); it was in use in Egypt 4,000 years ago, and in Europe till 12th century, when paper made from cotton began to take its place. The Romans made a stout brown paper from the bark of trees 800600. The Aztecs used the fibers of the maguey plant for the same purpose. The Arabs had paper-factories ab. 600, using raw cotton as the material, having learned the art from the Chinese. By the Arabs it was taken to Spain, whence it spread to other European countries. Italy started its first paper-mill 1250, Germany 1290, France 1340, England ab.1500, America 1690, at Roxborough, now in Philadelphia. The materials of which paper is made are numerous; the most important are linen and cotton rags, hemp, jute, straw, esparto and wood fibers. After cleansing by boiling with lime, the paper stock is reduced to fine fibers in water by the beating engine, consisting of a cylinder with knives revolving on a plate also furnished with knives, contained in a trough. The bleaching is done with chloride of lime, the excess being removed by washing and hyposulphite of soda. For sizing, a mixture of rosin, caustic soda, and alum is added to the pulp, and for colored papers the aniline colors are largely used. Much of the paper is loaded with mineral matter which is mixed with the pulp, the most common being china clay. The prepared pulp is suspended in water, strained, and run upon the paper machine.
