if it be going 5 if not, fet it a going , and pat the Indexes^ at 
•\^hat hour, min. and fee. you plcafe. Let them goe till Sun-fet, 
and when the Body of the Sun is juft half under the Horizon, 
fee, what hour, min. and fec^ the Indexes of the Watch point 
at, and note them too; and reckon, how m my houres &t, 
are Paffd by the Watch betweentheone and the other : which 
is done by adding to the Evening-- bfcrvation the hours 3^^. 
that the morning- Obfcrvation wanted of 12. or 24. in-cafe the 
Hour- hand hath in the mean time palFd that hour once or 
twice otherwife the difference only gives the time. Then 
take the half of that number, and add it to the hours, &c. of 
the morning Obfervation , and you (hall have the hours, 
which the Watch did fliow, when the Sun was in th^Southh 
whereunto add the Equation in the Table belonging to that 
day, and note the fumme. Then fome days being pa(I'd(the 
more the better,) you are to doe luft the fame; And if the 
hour of this Ia{t day be the fame, that was noted before, your 
Watch is well ad jafted ^ but if it be more or lefs , the diffe- 
rence divided by the number , elapfed between the two Ob- 
fervations, will give the daily difference. And if you will, you 
may let it reft there , or otherwife , removing the icfler 
weight of the Pendulum you may adjuft it better.
