[ [10] ‘A Century of the Names and Scantlings of such Inventions as at present I can call to mind to have tried and perfected, which (my former Notes being lost) I have, at the instance of a powerful Friend, endeavoured now, in the year 1655, to set these down in such a way as may sufficiently instruct me to put any of them in practice.’ London, 1663.
[ [11] The writer of the elaborate article “Lock,” in the supplement to the ‘Penny Cyclopædia’ (ii. 217), in describing the combination lock, says: “The Marquis of Worcester, in whose ‘Century of Inventions’ several different kinds of lock, which lay claim to the most marvellous properties, are enumerated, would appear, from his 72nd article, to have devised an improvement on this apparatus; as he refers to ‘an escutcheon to be placed before any of these locks,’ one of the properties of which he describes as being that ‘the owner, though a woman, may, with her delicate hand, vary the ways of coming to open the lock ten millions of times beyond the knowledge of the smith that made it, or of me who invented it.’ The details of this invention are not given; but in the third volume of the ‘Transactions of the Society of Arts,’ pp. 160–5, is an escutcheon of similar character, invented by Mr. Marshall, and rewarded by the Society in 1784. The details of this ingenious contrivance are fully given in the volume referred to.”
[ [12] His words are these:—“One of the most curious things that I wished to see was an hydraulic machine which the Marquis of Worcester has invented, and of which he is making trial. I went with all speed to Fox-hall, on the other side of the Thames, a little below Lambeth, which is the Palace of the Archbishop of Canterbury, in sight of London. This machine will raise to the height of forty feet, by the strength of one man only, and in a minute of time, four large buckets of water through a pipe of eight inches. But what will be the most powerful help to the wants of the public is the work which is performed by another ingeniously-constructed machine, which can be seen raised on a wooden tower on the top of Somerset House, which supplies that part of the town with water, but with some difficulty, and a smaller quantity than could be desired. It is somewhat like our Samaritane water-work on the Pont Neuf; and on the raising-pump they have added an impulsion which increases the force; but for what we obtain by the power of the Seine, they employ one or two horses, which incessantly turn the machine, as the river changes its course twice a day, and the spring or wheels which are used for the ebbing tide would not do for the flow.”—Sorbière, ‘Relation d’un Voyage en Angleterre.’

[ [15] Mr. Woodcroft is, however, of opinion that the Marquis’s contrivance was but a boat with paddle-wheels, with an axis across it, which axis was turned by the action of the stream on the paddles, and thus wound up a rope and dragged the boat onward to the other end of the rope fixed by an anchor; certainly a more clumsy and less notable contrivance than that of a steamboat.
