266 A Project for the Safety of NAVIGATION. for discovering where there is any "It is demonftrated by experi- From hence the father concludes, that a body which is but half immerfed, and confequently prefents but half its circumference to the im- E pulfion of the current, will receive from it but a velocity proportionable to its immerfion, that is to fay, a moiety; and confequently, thefe two floating bodies (meaning one wholly, and the other half immerfed) being at the fame inftant exposed to the F current, will feparate, because they will be pushed with two momentums of force, which will be to each other as one is to two, that is to fay, in proportion to their immerfions in every cafe. The father fays, that what he ad. G vances of the velocities and impulfions being to one another as the immersions, has not as yet been demonftrated; and that experiments aïe June neceffary for determining the true proportion between the velocities and immerfions; which may be eafily made. But this, fays he, being supposed, if you faften by two cords to the ftern of a fhip A, two balls, B and C, of which B fhall be wholly, or almost wholly, immersed under the furface of the water (Fig. 1.) and C but half immersed, B will be more impelled by the current, and the cords AC and AB, to which the balls B and C are tied, will not remain parallel in any place where there is a current; but the two balls, B and C, will approach to or remove from each other, according to their fituation with respect to that part from whence the current comes; Cfor if it comes from the fide of B, which is the most immerfed, the balls will approach together; whereas the contrary will happen, if it comes from the fide of C, which is the least immersed. This operation may be rendered ftill more fimple, if, instead of employing two cords, you put the balls B and C upon one and the fame cord (Fig. 2.) for then the fhip failing in feas where there is no current, the two balls will both follow her exactly in her line of direction; but if there is a current, the ball B, being more immerfed and impelled by the current, the card (Fig. 3.) on which the two balls are ftrung, will make an angle ABD, greater or lefler, according to the force with which the balls are impelled by the current. This experiment therefore will infallibly difcover the currents in the fea; but as they have directions different from the course of the,fhip, this experiment alone will not be fufficient, because the currents do not always make an impulfe upon the balls in the ratio of their velocities, but in that of the fines of the angle of their direction and the courfe of the fhip; for which reafon their impulfes may be often the fame, Fig. 4. An authentick Account of the Original Let the ball A be prepared of fome fort of fubftance which imbibes no water; for example, of any fort of hollow metal, the weight of B A ̧· which to be increased fo as that it fhall float just below the furface of the water, that is to fay, fo as that it may be almost intirely immersed : Let this ball be fixed at one end of a very flexible cord, ABC (Fig. 4.) By the other end ftring the ball B, C which for that purpose must be pierced thro' the middle; and to prevent friction, you may make ufe of little wheels or pulleys. This ball, B, must be made fo as to be but half immersed. D These things being prepared, if you throw these two balls close together upon the cord or rope into a current, the ball A will be drawn along with more velocity than the ball B; and if the immersion of B be fuch, that it makes but half of A, it is evident that the balls will fepa- E rate; and that during the time that B feparates itfelf from A, if B be come to the distance of a yard from A, the ball A will then have gone two yards, while B has gone but one. This will fhew the rapidity of the current; and the cord itself, on F which are the two balls, will shew the direction. You must proportion your cord, as near as poffible, to what the feparation of the balls and the course of the fhip may require." This is the fubftance of what father Francis fays, and upon this I could G make several remarks, but shall leave them to fome other opportunity, or to fome of your more ingenious correfpondents. I am, &c. H1 IS late royal highness being the eldest fon of our moft gracious fovereign George II. king of Great Britain, &c. was not only prince of Wales and earl of Chefter, but duke of Cornwall; (fee p. 148 G, 150.) and had precedence, not only by feveral charters, but by act of parliament, of all dukes, the king's fons, the king's brothers, the king's uncles, the king's nephews, or the king's brothers or fifters fons, who have precedency before all other dukes, and are princes of the royal blood of England. The earldom of Chefter, by king Henry III. was annexed to the crown for ever, by letters patent, dated the 31st of his reign, 1247, together with the caftles of Cannock and Diffard; and prince Edward, his eldest fon, was made earl thereof, whofe fucceffors have been the eldest fons of our kings; and the earldom of Chefter was united to the principality of Wales, by act of parliament, in 21 Richard II. The principality of Wales, being brought under fubjection to king Edward I. that monarch, by a flàtute made at Ruthlan, in the 12th year of his reign, united it to England; in which statute there are many laws concerning the division of L12 Wales 268 Of the Titles Prince of Wales, Duke of Cornwall, &c.

Whereupon the king And D victorious prince Edward, before he was feven years of age, in the parliament held at Westminster, 11 Edward III. as allo by charter, bearing date 17 March the fame year, being the first precedent for the creation of the title of a duke in England; to hold to himself, and his heirs, kings of England, and to their first-born sons."* But on the death of prince Henry, eldeft fon of king James I. fome doubt arose concerning this title; but that king in council heard the mafter of the Rolls, and the council of prince Charles, his fecond fon, and other great men ; and after grave and ferious deliberation, we find it fettled; as may be feen in the Proceedings B and precedents on baronies by writ, and other bonours, where the cafe of the duchy of Cornwall is mentioned at large: The chief doubt arofe out of "a literal conftruction of the words, filius primogenitus, contained in that fingular form of limitation of the faid duchy made by patent, enacted by parliament 11 Edward III. whereby the king did give the faid duchy and large poffelfions, &c. to have and to hold, &c. to the faid duke, and to the first-begotton fon of him, and his heirs, kings of England and dukes of the faid place, that hereditarily fucceed in the kingdom of England; fo as they may in no wife be separated from the faid duchy, nor be given, or any way granted by us, or our heirs, to any other or others, than dukes of the said place ;" yet it appeareth in the cafe of Richard, (after Richard II.) eldeft fon of the fame prince Edward, who died in the life-time of king Edward III. his father; by means whereof, he became lineal heir male to the king, that because he was not the eldest fon of a king, but of a king's fon, he was not duke of Cornwall by right of that grant and limitation, but was made dukeby king Edward III. by letters patent, and not by parliament. Henry VII. in the 10th of his reign, with the consent of the prelates, dukes, earls, and barons, in parliament, did make and create his fon Henry, prince of Wales and earl of Chefter; but did not create him duke of Cornwall, which he would have done, if he bad not been duke of Cornwall before by birth, without creation: Yet the king filed him his dearest second begotten fon, Henry duke of Cornwall, &c. for his elder brother Arthur died without iffue in his father's life-time; and by ftatute made a Henry V. it is expreffed, that the eldest fons of the kings of England, that should be next heirs to the crown of England, fhould be dukes of Cornwall; fo that in James the it's time, it was unanimoufly agreed and declared, that prince Charles, being next heir to the realm of England, Edward the Black Prince (fo furnamed F by the French, from his dreadful deeds in war) the eldest fon of Edward III. was the first invested in the principality of Wales, 16 Edward III. with these enfigns of honour, viz. a chaplet of gold, made in the manner of a garland; a gold ring, and a feepter of filver; to hold to himself, and his heirs, kings of England; from which time the heirs apparent of our G kings, have borne the title of prince of Wales, fome having been created in like form, others not.
