And after the fame Siihif you are to feek the tl^^ 
Watch when the Sun was in the South 5 which 78- --35--'48 
let be " -S 
But this Watch going 7. fee. a day too flow, it is retarded in 
91. dayes, (from the 20th of Febr. to the 2 2 , of May) 0—10—37 
Which therefore added to the faid time give$-8--49 — 25 
That is the fame time gtren by the Watch A, Now adding to 
thistimeof the Watches^the jEquationof the^ithlQ.^jg^j^ 
of May — • S,^ 
You have • — • — = ^9— 7—35 
Which isthe fame time of the day with that of the pla ce, 
where the Watches- were fet when the Sun was in thcfame 
Meridian with the Shipper where the Ship was at Noon.

The difference is — — . . -2 — 52—25 
Wherefore this laft Meridian is by fo much more Eafterly , 
than the fiffl: 5 which :being reduced to iicgrcts (as Mti been

formerly direded) mak e — — .43;-;.' 5-— 15 
Tis manifeft, that by this way you find precifely enough 
the Longitude of the place where you were at Noon, or 
the l ime of the Suns being in the South .- which, although ,ic 
differs from the Longitude of the place, where you iare^vvhen 
you obfervethe Setting of the Sun, yet you may eftimateneer 
enough 5 how much you have advanced, or chang'd the Lon- 
gitude in thofe few hours 5 by the Log-line, or other Ordi^ 
liary praflifes of reckoning the Ships way 5 or (which is the 
furer way j by the degrees pafs d in 24. hours by a former

You may alfo , inftead of obferving the Suns R 'fing and 
Setting, obferve the Setting firft , and then next morn ng the 
Rifing 5 marking at both times the Time fliow'd by the \^ arch- 
es^ and find thence, after the fame manner as before ^ the 
Longitude of the place wtoe the Ship was at Midnight. 
Finally, you may alfo, inftead of the Rifing and Setting 
of the Sun , obferve before and after Noon two equal Alritudcs 
of theSun 5 noting thetim^eftiowiiby the Watches, andreck- 
oning in the f^me manner, as hath been faid of ttie Rifing and
