“Dec. 11. Whitehall. Warrant for a grant to Sir Sam. Morland of the sole use for 14 years of his invention for raising water out of pits, &c. to a reasonable height, “by the force of powder and air conjointly.” “Dec. Whitehall. Vol. 46. No. 49. Warrant for a grant to Sir Sam. Morland of the sole making of an Engine invented by him for raising water in mines or pits, draining marshes, or supplying buildings with water.” The annexed reprinted title page is a facsimile for size and letter-press _within_ the gothic frame, employed to enlarge it. The smallness of the work was by no means unusual, indeed the first edition, in the British Museum, is bound in a volume uniform with the discourses of Sir William Petty, and of Dr. Grew, before the Royal Society, in 1674, issued by its own printer. Although more than ten years later the quaint style reminds one of the Dedications to the “Century,” as when Sir William says he was commanded to print his discourse--“Because, as drapers cut patterns of their whole cloth out of an end, not because the end is better than the rest, but because it may be best spared; so (I suppose) the Society are content, that this exercise pass for a sample, _pro tanto_, of what they are doing.” And of his second part he observes that it is “To excite the world to the study of a little Mathematics, by showing the use of Duplicate Proportions in some of the most weighty of human affairs, which notion _a child of 12 years_[G] old may learn in an hour.” Lastly, the Epistle Dedicatory informs us that:--“Falsity, disproportion, and inconsistence cannot be rectified by any sermocinations, though made all of figurate and measured periods, pronounced in tune and cadence, through the most advantageous organs; much less by grandiosonous or euphonical nonsense farded with formality; no more than vicious wines can be remedied with brandy and honey, or ill cookery with enormous proportions of spice and sugar: _Nam Res nolunt malè administrari_.” One example from Dr. Grew’s epistle to his discourse will suffice, where he says:--“I know, my Lord, that there are some men, who have just so much understanding, as only to teach them how to be ambitious: the flattering of whom, is somewhat like the tickling of children, till they fall a dancing.”
