The Nobleman and gentleman's director and assistant, in the true choice of their wheel-carriages : Being entire new designs for travelling-coaches, post-coaches, landaus both open and close, chariots, post-chariots, calashes, post-chaises, phaetons, and other vehicles, &c. curiously hung on steel springs. Being a work of universal use, not only to gentlemen, but coach-makers and spring-makers in general. The wholes and axle-trees are made of a proper height, so as to enable the horses to draw freely and with the greatest ease; many a fine horse having been totally spoiled by going up great ascents, and all owing to fixing improperly the wheels and axis. The whole drawn from original designs, executed and correctly engraved on thirty-six copper plates.
