A reply to Mr John James's Review of the several pamphlets and schemes , That have been offer'd To the Publick, for the Building of a Bridge at Westminster; wherein his many Absurdities are detected, and the Manner of Measuring and Calculating the Quantity and Weight of Materials in all Kinds of Arches, explain'd. By which 'tis evident, That Mr. James is absolutely a Stranger to so much Geometry as is needful to come at the Measures of the Quantities of Materials to be imploy'd in such a Work, &c. And that a semicircular Stone Arch of 120 Feet in Diameter, has not so great a Pressure on its Base, as many Publick Buildings in this Kingdom have on theirs. Also, The Nature of the Tides, and Fall of Water at London Bridge, fully Explained. The Whole Exemplify'd by Geometrical Diagrams, and New Designs; demonstrating the Nature and Easy Performance of so great a Work. By B. Langley.

A survey of Westminster Bridge , As 'tis now sinking into ruin. Wherein the cause of the foundation giving way under the sinking pier, and its dislocated arches, is not only accounted for; but also, that the whole structure is likewise subject to the same immediate (if not unavoidable) ruin. With remarks on the piratical method used for building the piers. And a just estimate of the expence for which all their foundations might have been made secure with piles, until every stone, with which the bridge is built, was torn into atoms, by the hungry teeth of devouring time. By Batty Langley, of Meard's Court, Dean-Street, Soho, architect.

A design for the bridge at New Palace Yard, Westminster, (inscribed to the Right Hon. the Lords and gentlemen, appointed commissioners for building the same) composed of nine arches, independent of each other; whose nature is such, that the greatest weight possibly to be impressed cannot break them down. Admitting 880 feet water-way for the flux and reflux of the tides . Wherein is demonstrated, I. The several manners that the tides will be affected by this building. II. The greatest fall of the water truly calculated; with remarks on an erroneous calculation of 4 inches and seven ...ths, lately published. III. Methods for laying the foundations of the piers in the most substantial and expeditious manner, and to erect them with the same ease as on dry land, without obstruction to the navigation. IV. A near calculation of the cubical feet contained in the whole fabrick; the expence it built entirely with stone, or with stone and brick. V. The great use and advantage of horizontal cylinders, for adjusting an equal pressure on the sides of each arch. A work entirely new, by which an expence of 24,174l is saved, and the building made stronger also. With observations on the several designs published to this time, proving the abutments of their arches to be infirm, and the possibility of their falling, by means of which the whole will be in danger. By B. Langley.
