Paradise Lost. Milton's purpose to write a great epic was formed as early as 1689. On his return to England from the Continent he was occupied in the choice of a subject. A list of those considered remains; 61 were Scriptural, 88 from British History. The first on the list was finally chosen. For a time he wavered between a dramatic and an epic treatment. During the 20 years of his controversial life the poem was laid aside. It was taken up 1658, and was nearly finished 1663. It appeared 1667 in 10 books; the 2d ed., 1674, had 12, books VII. and X. being subdivided, and 8 lines added in books VIII. and XII.

that half of its orbit nearest the sun, the effect of the latter is greater than while the other half is described.

Parallactic Orbit OF A Star. A star which has a measurable parallax appears to describe a small orbit with a period of one year. The orbit is an ellipse whose semi-major axis is equal to the annual parallax. The motion is only apparent, being due to the earth's annual motion about the sun. Parallax. Difference in apparent position of a body as

seen from two points. The diurnal parallax of a planet is the difference in apparent position as seen from the center of the earth and a point on the surface. The annual parallax of a star is the angle at the star subtended by the radius of the earth's orbit. The equatorial horizontal parallax of the sun or a planet is the parallax when seen in the horizon from a point on the earth's equator. Parallax, Solas. Angle at the center of the sun, subtended by the earth's equatorial radius. Various methods have been employed for measuring its value, the most important being by transits of Venus across the sun's disk, by observation of Mars near opposition, and by the velocity of light. Some of the values which have been found for this constant are as follows: Ptolemy 3', Cassini 9.5", Encke 8.5776", Newcomb 8.848". Most recent determinations about 8.79". Calculated from this the distance of the sun from the earth is about 93,000,000 m.

definition. If two lines be perpendicular to a third: or both parallel to a third: or make alternate interior angles equal, or the sum of the interior angles on one side of the transversal equal to two right angles, they are parallel. If the lines are given by their equations, they will be parallel when their slopes are equal; y --■ mx -)- b, y ~ m'x -f- b1 are parallel if m — m1.

Parallel Hoi ions.

Parallelogram of Forces. If two forces can be represented in magnitude and direction by the two adjacent sides of a parallelogram, the diagonal of the parallelogram colinear with the two forces will represent their resultant in magnitude and direction. The case is applicable to two velocities or two accelerations, and so we have the parallelogram of velocities and that of accelerations. In general, the principle can be applied to any two directed quantities whatever.

Parallelopiped. Prism the bases of which are parallelograms. If the lateral edges are perpendicular to the base, it is a right parallelopiped: if in addition the bases are rectangles, it is rectangular. The volume of a parallelopiped equals the product of its base and altitude. The name Cuboid has been suggested for the rectangular parallelopiped.

Paranahj ba. See Parnahyba.

Paranoia. Form of mental disease. While there is a defective nervous organization from birth, the manifestations of mental alienation are frequently so slight as to mislead an expert. Youthful precocity, some eccentricity of conduct, or a slight morbidness may be the only manifestation. Many of the enthusiasts and cranks of the world, who are able to carry on complex affairs to a successful termination, are but illybalanced paranoiacs. Were it not that the disease tends to chronicity and not to cure, and, as it progresses, seizes its victims with delusions leading to crime, it may be to homicide, it might be classed as a harmless affection.

Paranucleolu§. In Plant Cytology, secondary nucleolus. Paranucleus. Secondary nucleus, sometimes seen in different cells, outside the principal nucleus. In Protozoa it is the micronucleus or endoplastule; in eggs it is the yolk nucleus. Accessory nuclei are present in nearly all sorts of cells, but are probably not homologous structures.

In India, in the game called Pachisi or Twenty-five, from which the American game is borrowed, the moves are made according to the throws with Cowrie shells. In our game dice are employed; the corresponding Hindu dice game is called Chansar. From internal evidence it appears that pachisi was originally cosmical and divinatory, the four arms of the cross being referable to the four directions. An almost indentical game was played by the ancient Mexicans under the name of Patoli. The latter is regarded by many as conclusive evidence of the Asiatic origin of Mexican culture, but is likely to have developed independently in Asia and America. Pachisi is widely diffused in Asia, from the Philippine Islands toSvria, where it is known as Edris. It was introduced into the fj. S. 1865.
