Seating
A guide-bearing or rest for cores or mould sections. In vertical loam-work the cope or the core, and sometimes both, are made as separate portions of the mould, and must be lowered into their respective positions when the mould is closed together in the pit. In order that this may be done accurately, a tapered seating is formed at the bottom of the mould, extending some few inches below the casting. By this device the smallest end of the core is made to enter at the widest diameter of the seating, and is thus guided to the bottom-bearing, when the sides meet close together at a true centre. The cope is the opposite to this, its widest diameter seeking a true location by inclosing the small end of the seating first, and gradually embracing it closer and closer until the bottom-bearing is reached, when the diameters correspond and the section is central. The tapered sides of an ordinary core-print represent the seating for a core. See COPE-RING; PRINT; GUIDE.

Secant
in geometry, a straight line cutting a curve in two or more points. If a secant line be revolved about one of its points of secancy till the other point of secancy coincides with it, the secant becomes a tangent. If it be still further revolved, it again becomes a secant on the other side; hence, a tangent to a curve, at any point, is a limit of all secants through that point. A secant plane is one which intersects a surface or solid. In trigonometry, a straight line drawn from the center of a circle through the second extremity of an arc, and terminating in a tangent to the first extremity of the arc.

THOMAS, Archbishop of Canterbury; born in Sibthorpe, Nottinghamshire, in 1693; son of a Dissenter of independent means, who wished him to enter the ministry of his own communion. In 1716, however, the son turned to medicine, taking his doctorate in physic at Leyden in 1721. Meanwhile, urged by his old schoolfellow, Joseph Butler, he had decided to take Anglican orders; in 1722 he graduated B.A. at Oxford, and in that and the following year he was ordained deacon and priest. His preferments were Houghton-le-Spring (1724), Ryton and a prebend at Durham (1727), chaplain to the king (1732), St. James's, London (1733), Bishop of Bristol (1735), of Oxford (1737), Dean of St. Paul's, for which he resigned the living of St. James's (1750), and the primacy (1758). He died Aug. 3, 1768.

Seconds Hand Remover and Holder
The minuteness of the second hand makes it very difficult to manipulate. The little tool shown in Fig. 281 will be found very useful in handling these hands. To use it, raise the spring with the thumb, and push the tool along the dial astride the arbor; then let go the spring and raise the tool. The spring will hold the second hand firmly until replaced. For broaching, hold the tool, spring side down, firmly on bench or vice.

Secret Fire
Described by Philostratus as issuing from a basin in a well on the hill Athanor . A blue vapour rises from the well, changing into all the colours of the rainbow. The bottom is strewn with red arsenic; on it is the basin full of fire, and from it rises flame without smell or smoke. Two stone reservoirs are beside it, one containing rain, the other wind.

Secret Words
Certain words relating to the Eucharist were communicated by Christ to Joseph of Arimathea and were committed orally from keeper to keeper of the Graal. In Robert de Borron's metrical romance, material power is added to their spiritual efficacy and whoever could acquire and retain them, had a mysterious power over all around him, could not suffer by evil judgments, could not suffer deprivation of his own rights, need not fear the result of battle, provided his cause were good. The words were the secret of the Graal and were either incommunicable in writing or were written only in the Book of the Graal which, de Borron implies, was itself written by Joseph of Arimathea. These words are the chief mystery of the Lesser Holy Graal, as the prose version of de Borron's poem is called. They were most probably a form of eucharistic consecration, and there is evidence that the Celtic church, following the example of the Eastern Church used them in addition to the usual consecration as practised in the Latin Church, which is merely a repetition of the New Testament account of the Lord's Supper. The separate clause they are supposed to have formed is called Epiclesis and consisted of an invocation of the Holy Ghost.
