Palaeozoic. All fossiliferous strata below the top of the

Permian. See Column.

Palaeozoology. Science of the distribution of animals in the strata of the earth's crust. The oldest strata (Archasan or Laurentian rocks) represent the Azoic period, when living things had not yet appeared, or if they lived, their remains have not been preserved. Next comes the Palaeozoic period, characterized by fossil forms most different from species now living. This age includes the following periods: the Cambrian, Ordovician, Silurian, Devonian (Old Red Sandstone), Carboniferous or coal-age, and Permian. The great classes of animals up to and including Ichthyopsida had become evolved in these periods. The next age is the Mesozoic (secondary period), including the Triassic. Jurassic, and Cretaceous rocks. The Sauropsida became established during-these periods. Finally, the Kainozoic (Tertiary) Age includes the Eocene, Miocene, Pliocene, Post-Pliocene (Post-Tertiary), including the present (Quaternary) period. During this age the Mavimalia became established. The most Synthetic Types (q.v.) are always found in the earlier formations. See Paleontology.

Paleography. See Diplomatics.

Paleolithic Man. The presence of rough stone implements in the early drift in caves and along river courses, associated with the remains of the Cave Bear, Hyena, Elephant, Mammoth, and Rhinoceros, in Europe, and similar remains in America, shows that man was widely distributed over the globe at the close of the glacial epoch, following the retreating ice northward, and perhaps living and hunting like the Eskimo, though there is doubt if the modern Eskimos are related directly to that race.

Paleontology. Science that treats of fossil remains, both animal and vegetable; now often restricted to the former. It has risen to so high a position for accuracy that it is the main dependence of the geologist in determining the age of strata. The fossil faunas of the different systems are so well known that the geologist in a new country need only collect its fossils and compare them, in order to ascertain their horizon. Much time and labor are thus saved. From Paleontology we learn that a regular gradation of organic life has existed among fossils, and that this gradation corresponds closely with that of the existing world of life, indicating a steady progress in development from the beginning. But it has not yet found any of the earliest forms. In the lowest Cambrian, from which the oldest intelligible fossils have been obtained, all the great subdivisions are present except the vertebrates. The first chapter in the evolution of the organic world is consequently yet unknown. See Palaeozoology.

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

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.
