The said _Major_ having left that Coast, and being come to the Isle of St. _Thomas_ under the _Line_ accompanied with four Vessels, having there adjusted his Watches, put to Sea, and sailed Westward, seven or eight hundred Leagues, without changing his course; after which, finding the Wind favourable, he steered towards the Coast of _Africk_, North-North-East. But having sailed upon that _Line_ a matter of two or three hundred Leagues, the Masters of the other Ships, under his Conduct, apprehending that they should want Water, before they could reach that Coast, did propose to him to steer their Course to the _Barbadoes_, to supply themselves with Water there. Whereupon the said Major, having called the Master and Pilots together, and caused them to produce their Journals and Calculations, it was found, that those Pilots did differ in their reckonings from that of the Major, one of them eighty Leagues, another about an hundred, and the third, more; but the Major judging by his _Pendulum-Watches_, that they were only some thirty Leagues distant from {14} the Isle of _Fuego_, which is one of the Isles of _Cape Verde_, and that they might reach it next day, and having a great confidence in the said Watches, resolved to steer their Course thither, and having given order so to do, they got the very next day about Noon a sight of the said Isle of _Fuego_, finding themselves to sail directly upon it, and so arrived at it that Afternoon, as he had said. These Watches having been first Invented by the Excellent Monsieur _Christian Hugens_ of _Zulichem_, and fitted to go at Sea, by the Right Honourable, the Earl of _Kincardin_, both Fellows of the _Royal Society_, are now brought by a New addition to a wonderful perfection. The said Monsieur _Hugens_, having been informed of the success of the Experiment, made by _Major Holmes_, wrought to a friend at _Paris_ a Letter to this effect;
