Plymouth Brethren
a body which arose almost simultaneously in Dublin and Plymouth, about 1830, and, as they called themselves "The Brethren," outsiders came to know them as "Plymouth Brethren" from the town where they had fixed their headquarters PLYMOUTH ROCK PNEUMATIC TOOLS Their chief founder was a lawyer, named by Latimer Clark in 1853, improved by Darby, who had taken orders. Their communities are of what is known as the Evangelical Calvinistic type, and many of them maintain that only among themselves is true Christianity to be found. They have no regular regular ministry, every brother being at liberty to prophesy or preach whenever moved to do so. They baptize all adults, whether previously baptized or not, and observe the Sacrament of the Lord's Supper weekly. They are rigid Predestinarians and expect the millennium. Varley in 1858, and again by Siemens in 1863. The invention of Latimer Clark and Varley required a separate tube between each pair of stations, and admitted of only a single dispatch at a time; but a system of laying tubes in circuit for the continuous transmission of dispatches, by by means of an uninterrupted air current in one direction, was adopted in Berlin by Siemens and Halske in 1863, and introduced in London in 1870.
Both systems are in use in London with modifications to suit special traffic. luc 41620号 PLYMOUTH ROCK PLYMOUTH ROCK. See PLYMOUTH (Mass).
