Pratt, Orson (1811-81), Mormon apostle, brother of Parley Parker Pratt, was born in Hartford, N. Y. In 1830 he joined the Mor- mon Church, and by 1835 had become one of the Twelve Apostles. He was one of the first to enter Utah, and was seven times speaker of the Utah House of Representatives. In August, 1870, he engaged in a debate with Dr. John P. Newman, chaplain of the U. S. Senate, on the subject of polygamy. The de- bate took place in the great tabernacle at Salt Lake City, and attracted widespread attention. By his numerous successful mis- sionary journeys to the East and to Europe, he gained for himself the designation, 'the Paul of Mormonism.* Pratt, Parley Parker (1807-57), Ameri- can Mormon apostle, brother of Orson Pratt, was born in Burlington, N. Y. He became a member of the Mormon Church in 1830, was chosen one of the Twelve Apostles in 1833, and was one of the first Mormons to visit Salt Lake. In 1857 he was murdered near Van Buren, Ark.

Pratt Institute, a technical school in Brooklyn, New York, founded and endowed in 1887 by Charles Pratt, with the object of promoting industrial education. The Institute offers to men and women day and evening courses in a wide range of art, scientific, me- chanical and household subjects and con- ducts teacher training courses in fine and ap- plied arts.

Praxiteles, a celebrated Greek sculptor, who is often ranked next to Phidias for the perfection of his work. He was a citizen, if not a native, of Athens, and lived about 400- 330 B.C. The chief characteristics of his work are the perfection of his modelling, and the ; way in which he makes his statues represent , some mood or feeling. During the excavations i at Olympia a nearly perfect statue of Her- , mes by him was discovered. Other statues ! attributed to him are even more famous, es- pecially an Aphrodite, which he made lor the Cnidian?, an idea of which may be gained from a copy in the Vatican, and the basis of a group representing Apollo, Artemis and Leto in the presence of the Muses excavated at Mantineia. Pray, Isaac Clark (1813-69), American journalist and playwright, was born in Bos- ton. In 1836 he became proprietor of the National Theatre in New York, where he produced his tragedy Guilictta Gordon and several other plays. He became dramatic critic for the New York Herald in 1850, and wrote and translated several plays, the most successful of which was Vlrginius. Prayer, Book of Common, the name giv- en to the service book of the Anglican and Protestant Episcopal Churches. The existing English service books are nearly all of the Roman type. Uniformity was not arrived at until the sixteenth century, which produced both the Book of Common Prayer and the Tridentine revision of the Roman services. From the thirteenth century to the Refor- mation there were three principal 'uses' in English: those of Salisbury, York, and Here- ford. The Salisbury or Sarum use has most influenced the present Prayer Book. The movement for reformation in the public serv- ice of the English Church originated during the latter years of the reign of Henry vm. On June n, 1544, were 'set forth certain godly prayers and suffrages in our native English tongue,' also a Litany which is prac- tically the same as the present Litany in the Prayer Book. A committee of convocation sat for seven years, and produced the Prayer Book of 1549 (the first Prayer Book of Ed- ward vi.). The second Prayer Book was published in 1552. After Elizabeth's accession a commit- tee was appointed to deal with divine serv- ice, and a Prayer Book was ready for pub- lication in 1559. It is practically the same book as that now used in the Church of England. The commonwealth formally sup* pressed the Book of Common Prayer on Jan. 4, 1645, and it was out of use until the restoration on May 26,1660, when the Prayer Book was revised on lines as conciliatory as possible, without sacrifice of essentials, and was authorized in 1662.
