le on an axis perpendicular to that of the lathe; and of cutting out concentric shells by fixing in a similar manner a curved tool of nearly the same form as that employed by common turners for making bowls. "In fact," says Mr. Mallet, "Bramah not only anticipated, but carried out upon a tolerably large scale in his own works--for the construction of the patent hydraulic press, the water-closet, and his locks--a surprisingly large proportion of our modern tools." [6] His remarkable predilection in favour of the use of hydraulic arrangements is displayed in his specification of the surface-planing machinery, which includes a method of running pivots entirely on a fluid, and raising and depressing them at pleasure by means of a small forcing-pump and stop-cock,--though we are not aware that any practical use has ever been made of this part of the invention. Bramah's inventive genius displayed itself alike in small things as in great--in a tap wherewith to draw a glass of beer, and in a hydraulic machine capable of tearing up a tree by the roots. His powers of contrivance seemed inexhaustible, and were exercised on the most various subjects. When any difficulty occurred which mechanical ingenuity was calculated to remove, recourse was usually had to Bramah, and he was rarely found at a loss for a contrivance to overcome it. Thus, when applied to by the Bank of England in 1806, to construct a machine for more accurately and expeditiously printing the numbers and date lines on Bank notes, he at once proceeded to invent the requisite model, which he completed in the course of a month. He subsequently brought it to great perfection the figures in numerical succession being changed by the action of the machine itself,--and it still continues in regular use. Its employment in the Bank of England alone saved the labour of a hundred clerks; but its chief value consisted in its greater accuracy, the perfect legibility of the figures printed by it, and the greatly improved check which it afforded. We next find him occupying himself with inventions connected with the manufacture of pens and paper. His little pen-making machine for readily making quill pens long continued in use, until driven out by the invention of the steel pen; but his patent for making paper by machinery, though ingenious, like everything he did, does not seem to have been adopted, the inventions of Fourdrinier and Donkin in this direction having shortly
