Not illustrated. 1902 Excerpt: ...earth. r' = radius of moon, or other body. P = moon's horizontal parallax = earth's angular semidiameter as seen from the moon. f = moon's angular semidiameter. Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

Dickens introduces this novel with several chapters of pure fiction set in 1775, laying out two romance plots and a murder mystery. Then the story jumps ahead five years to the Gordon Riots of 1780 ... Read full review

### About the author (2007)

Charles Dickens, perhaps the best British novelist of the Victorian era, was born in Portsmouth, Hampshire, England on February 7, 1812. His happy early childhood was interrupted when his father was sent to debtors' prison, and young Dickens had to go to work in a factory at age twelve. Later, he took jobs as an office boy and journalist before publishing essays and stories in the 1830s. His first novel, The Pickwick Papers, made him a famous and popular author at the age of twenty-five. Subsequent works were published serially in periodicals and cemented his reputation as a master of colorful characterization, and as a harsh critic of social evils and corrupt institutions. His many books include Oliver Twist, David Copperfield, Bleak House, Great Expectations, Little Dorrit, A Christmas Carol, and A Tale of Two Cities. Dickens married Catherine Hogarth in 1836, and the couple had nine children before separating in 1858 when he began a long affair with Ellen Ternan, a young actress. Despite the scandal, Dickens remained a public figure, appearing often to read his fiction. He died in 1870, leaving his final novel, The Mystery of Edwin Drood, unfinished.
