the Ifle ofF^^g^jWhich is one of the Ifles o[Cape Verd^zwA that they 
might reach it next dayjand having a great confidence in the (aid

©rder fo to do^ they got the very next day about Noon^a fight of

and fo arrived at it that AfternooUj as he had faid. Thefe 
Watches having been firft Invented by the Excellent Mounfieur 
Chrijiian Hngens 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 perteftion. The laid Monfieur Htigens^ having been in- 
formed of the fuceefsofthe Experiment^made by Major Holmis^ 
wrote to a Friend at Faris a Letter to this effefl: 5 
Major Holmes M his return^ hath made a relation concerning 
the ufefulnefs of Fendulums^ which furpafleth my expedation. 
I did not imagine that the Watches of this firft Strudure would

New ones. But feeing that thole have already ferved lb liiccef-

they have granted my requcft, commanding me to bring one 
of thele Watches into their Aflembly , to explicate unto them 
the Invention , and the application t\\txco( to t\\Q Longitudes 
which I have done to their contentment. I have this week pub-

with an nfoi mation neceflary to ufe them at Sea : and thus I
