A Brief Explication of the parts of the first table  
a The centre with a little Ball Representing the globe of the Earth.  
bb &c The orbs of the Respective planets having their Epicycles afixt in them  
cc &c Shaded lines Representing the Epicycles of the Several planets  
dd &c The centres of the Epicycles Showing their Middle Motion ☿ ♀ ☉ ♂ ♃ ♄ Show what planets the Asterisks to which they are affixed Represent, and the Asterisks themselves Show the apparent place of their respective planets in the Zodiac by a line from the Centre to the Asterisk continued to the sign and degree of the Zodiac, as ♄. 28D. of ♏. ♃. 20D. of ♈ ♂ 28D. of ♒. the ☉ near 20D D of. ♈. ♀. 3 D of ♓. ☿. 26D. of ♓. and the Moon. 6D. of ♍ when they are direct Swift or Slow Stationary or Retrograde may be Known by obserueing in what part of the Epicycle the planet is or more Mechanically by Seeing the motions of the work.  
The Apogaeons' perigaeons and aspects and the Elongations of ♀ and ☿ etc. are sufficiently evident to the intelligent Spectator by observing in what part of their Epicycle they are in and how far distant from each other as ♄ approaching near his perigaeon ♃ in his Apogaeon and ♀ drawing towards her Elongation etc.  
ee The 12 Celestial Sign's as computed from the first Star of Aries with the most Remarkable fixed Stars in and about the Zodiac having a proper Motion of about one degree in a 100 years etc.  
fff &c The Signs of the Zodiac with the Number of their degrees reckoned from the Vernal Equinox  
gg &c The 24 hours of the Natural Day Serving for the observation of the horary distance between planets of different Longitude, or planets or other Stars &c  
hh &c The degrees of terrestial Longitude adapted to the Longitude of London Serving for the Knowledge of the Southing &c of any of the planets or other Star's to that or any place of Known Longitude &c  
two The Lamina on the Eastern and Western sides of the table with the Characters of the 12 signs of the Eccliptick Fitted for the Latitude of London Showing the length and Shortness of the Day, And the exact Riseing and Setting of the Signs of the Zodiac with the Stars and planets in them, each Sign then Rising when it comes over against its Correspondent Sign in the Eastern Lamina and setting when it comes to the like on the other side, And the arch above or below these Show (and with the Circle of hours) the Space of time which they make above or below the Horizon   

The Explication of the: 2d: Table  
a The centre Representing the Earth  
kk &c The orb of the Moon  
ll &c The centre of her Epicycle Showing her middle Motion  
mm &c The Moon in her Epicycle Showing her apparent place in the Zodiac her Apogaeon and perigaeon having the Hemisphere next the Sun always Illuminated Serving to Show her Various phases &c  

nn etc.  Two Circles one Representing the Eccliptick the other the Orbit of the moon with figures enclosed to show the degrees of her Latitude 


N ☊  The North Node  

S ☋  The South Node   having their proper Motion  
oo &c The Sun placed here the better to show his Aspects with the Moon and Eclipses;  
The Eclipses, their quantity, Duration and the parts of the earth which they are Visible in etc. are to be known by considering the Latitude of the Moon in her conjunction and opposition with the Sun and the Longitude and Latitude of the Respective places; the Rules for which are here for brevity Sake omited;  
pp &c Remarkable Stars in their proper Longitudes which are more Remote from the Eccliptick than those in the former table;  
The other parts of this table are Sufficiently Explaind in the Former   

The 3 Table  
qq &c The innermost Circle by figures from 1. to 28. tells the Cycle of the Sun; The second shows the Dominical Letter; the next shows the months, and the 4 Circles Surrounding it, tells the day of the Month, to be accounted on the inermost the first year after Bissextile; and So Succesively to the outermost; which Serves for leap year   

The 4th Table  
rr The innermost Circle shows the Indiction; the middle the golden Number; the outermost the Epact:   

The Middle Table  
S.M.T.W.T.F.S. are the first Letters of the days of the week with their primary planet and in the Circle encompasing them is showed the hours of the Day computed from 12 to 12:  
SS A hole for a Key whereby the whole Machine as depending on one Axis) may be moved for any Number of Days months or years either backward or forward presenting to the eye the forementioned phaenomenae happening in that space of time, and then being returned to the present year Month Day and hour Keeps the time for the future, So that upon occasion of any neglect in drawing up the weight which moves the long pendulum (which need be done but once in Eight Days) the whole is set right;
