“Saturday night, 26th of January, 1660, be therefore pleased to pardon the scribbling, and regard but my real meaning. For the Right Hon. the Earl of Lotherdale, &c. these.”
(Copy of the enclosure.)
“The name and the truly significant definition of a most admirable and most stupendous invention, through the providential dispensation of the Almighty God’s infinite mercy and goodness, found out, and perfected by the sole expenses, ingenuity, knowledge, and mathematical insight of the Right Hon. Edward Somerset, Marquis of Worcester, and by his Lordship deservedly termed, and pithily defined to be—
“An Imperial, or a Water-commanding Engine, boundless for height and quantity, and requiring no external, nor even additional help, or force to be set, or continued in motion, but what intrinsically is afforded from its own operation, nor yet the twentieth part thereof, and the engine consisteth of these following particulars:—
“1. A perfect counterpoise for what quantity of water soever.
“2. A perfect countervail for what height soever it is to be brought unto.
“3. A primum mobile, commanding both height and quantity, regulator-wise.
“4. A vice-gerent, or countervail, supplying the place, and performing the full force of man, wind, beast, or mill.
“5. A holme, or stern, with bit and reins, wherewith any child may guide, order, and control the whole operation.
