chance or carelefnefs all the Watches (hould come to ftand 
ftill , yet you may at anyplace, whereof the Longitude is cer- 
tainly known, fet them a going again , and adjuft them there 
by the Sun, and fo reckon the Longitudes from that fame Me- 
ridian, For y you are to know , that you are nor at all obli- 
g'd to put cerpain Meridian of any knowne place as a begin- 
ing of the Longitude-reckoning • this hapening only in MappSj 
or Tables of Longitude : As, when you take for that purpofe 
the Meridian offlie Fico in Teneriffe^ or that of the Iflands of 
Xorvo and T lores (the moft Wefterly of the Azores^ or any 
others. Yet it were very fit, that txW ceographers agreed and 
pitched upon one and the fame P/V/? Meridian , that fo all places 
might be known by the fame Degtees as well of Longitude 2s 
of Latitude r, though in Voyaging it is fufficienc, toobfeve 
only the difference of Longitudes, beginning to reckon from 
the Meridian of any place, y6u pleafc, as if it were the

you may know, how much you advance from that place -toivarcfe
