the Ille ofF#e£<7, which is one of the Ifles of Cape Herd % and that they 
might reach it next day,and having a great confidence in the faid 
Watches 5 relblved tofteer their Courfethither,and having given 
order lb to do, they got the very next day about Noon,a fight of 
the faid Ille of Fuego, finding themfelves to fail direftly upon it, 
and fo arrived at it that Afternoon, as he had laid. Thele 
Watches having been firft Invented by the Excellent Mounfieur 
Chrifiian Hugens of Zulichem , and fitted to go at Sea, by the 
Right Honourable, the Earl of Kincardine both Fellows of the 
Royal Society , are now brought by a New addition to a won™ 
derfull perfe&ion. The faid Monfieur Hugens , having been in- 
formed of the fuceefsofthe Experiment,made by Major Holmes 
wrote to a Friend at Paris a Letter to this effe& $ 
Major Holmes his return, hath made a relation concerning 
the ufefulnefs of Pendulums , which lurpalleth my expe&ation. 
I did not imagine that the Watches of this firft Structure would 
fucceed fo well , and I had referved my main hopes for the 
New ones. But feeing that thofe have already ferved lb fuccefi 
fully, and that the other are yet more juft and exad, I have 
the more reafon to believe, that the Invention of Longitudes will 
come to its perfection. In the mean time, I (hall tell you, that 
the States did receive my Propolition, when I defired of them a 
Patent for thefe New Watches, and the recompenle let a-part for 
the invention in cafe of fuccels 5 and that without any difficulty 
they have granted my requeft, commanding me to bring one 
of thele Watches into their Aflembly, to explicate unto them 
the Invention , and the application thereof to the Longitudes 5 
which I have done to their contentment. I have this week pub- 
lifhed , that the laid Watches fball be expofed to fale , together 
with an Information necellary to ufe them at Sea: and thus I 
have broken the Ice. The fame Objedlion, that hath been made 
in your parts againft the exaftnefs of thele Pendulums , hath alfo 
been made here $ to wit , that though they Ihould agree toge- 
ther , they might fail both of them, by realbn that the Air at one 
time might be thicker, then at another. But I have anfwered, 
that this difference , if there be any, will not be at all perceived 
in the Penduls , feeing that the continual Obfervations , made 
in Winter from day to day, until Summer, have Ihewed me, that
