By the help of this table you will always know, what a 
Clock it is by the Sun precifely, and confequently , whether 
the Watches have been fet to the right meafure of the 
day 5 or no ^ ufing the Table , as follows. 
When you firft fet your Watch by the Sun, youaretofub- 
du(a from the time obferved by the Sun , the t/Cquation ad- 
joyned to that day of the Month in the Table, and to fet the 
Watches to the remaining hours, minuts and fcconds , that Is, 
the Watches arc to be fet fo much flower , than the time of 
tii^ Sun, as(in the Table) is the «^quation of that day 5 fo 
that the t^quation of the Day, added to the time of the Clock, 
is the true time by the Sun. And when after fome days , you 
defire to know by the Watch the time by the Sun , you are 
to add to the time, fliew'd by the Watch, the t/^quation of 
^hat day 5 and the Aggregate lhall be the time by the Sun , if 
the Watch hath been pertedHy well adjufted after the meafure 
of theii/^4/^ days 5 for the doing of which, this will be a Con- 
venient way 
Draw a Meridian line upon a floor (the manner of doing 
which is fufliciently known 5 and note, that theutmofl: exa^nefs 
herein is notneceflary :) and then hang two plummets, each 
by a fmall thred or wire, dire(aiy over the faid Meridian, at 
thediftance of fome 2. foot or more one from the other, as 
the fmalnefs of the th ed will admit. When the middle of 
the Sun (the Eye being placed fo , as to bring both the threes 
into one line) appears to be in the fame line exaSly (for the 
better and more fecure difcerning whereof, you muft befurnifli't 
with a glafsof a dark colour, or fomewhat blackt with the 
fmoak of a Candle ,) you are then immediatly to fet the Watch, 
not precifely to the hour of 12. but by fo much lefs, as is 
the <i^:quation of that day by the Table. E. g. If it were 
the i 2 of March ^ the ^^quation of that day being by the 
Table, 8 min. ^ fee thefe arc to be fubduded from 12. hours, 
and the remainder will be 11. hours, 51. min, 57, fee 5 to 
which hours ^ minutes and fcconds you are to fet the index oi 
the Watch refpedively: Then after fome days you are to ob- 
ferve again in the fame manner, and likewife to note thehour, 
min. and fee, of the Watch-, to which you are to add the 
t^£quation
