 46 min. in the Figure abovenamed.

An Introduction to Astrologie.

I enter down the first column, and find 46, against it I find 1 min. 55 seconds to be one hours motion of Mars, when in 24 hours he moves 46 min.

You must note, if you enter with minutes, you must have minutes, if with seconds, seconds; and so in the rest: This in the motion of Saturn Jupiter, Mars, Sun, Venus, Mercury; with the Moon otherwayes.

If the motion of your Planet be above 61 min. viz. 70 or 75 or 80 min. then enter the Table twice:

as for example.

The motion of Mercury is, as you perceive, 1 degr. and 27 min. I would know what his hourly

motion is, I enter first with 60 min. against which I find 2,30, viz. 2 min. 30 seconds, then I enter

with 27, against which I find 1,7,30, viz. 1 min. 7 seconds, thirty thirds, which I cast away, and

adde the two former summes together thus, 2 30

1 7

3 37 added together they make 3 min. 37 seconds, and so much is the hourly motion of Mercury, when his diurnall motion is 87 minutes.

The daily motion of the Moon you see is 12 degrees and 7 minutes. I enter down the first column with 12, against it I find 0,30,0, viz. 0 degr, 30 min. 0 seconds.

I enter with 7, over against it I find 0 17 30

I adde the number to it 30 0 0

they produce 30 minutes 17 seconds, and 30 thirds for the hourly motion of the Moon in our figure: you may in her operation reject the seconds and thirds.

By this rule I would know where the true place of the Sun is at that hour when we erected the Figure.

The hour of the day is 1:30, the time admitted by Eichstadius for reducing his Ephemeris to the

Meridian of London, is 50 min. of an hour in motion, for they being more East then we, the Sun

comes sooner to them at their noon, then to us that are more West-ward, by so much time: I adde

50 min. to my former time, viz. 1.30, the whole is then 2 hours and 20 min. now if the motion of

the Sun in one hour be 2 min. 32 seconds

then in two hours it will be 2 min. 32 seconds more.

added together they are 5 min. 04 seconds.
