of observation is by Eclipses of the Sunne & Moone, which in
severall Countries are sooner or later seene, according as one
place lies farther East or farther West from another. But this
also falls out so seldome, and when it happens, is so seldome
obserued, and when it is observed, hath so many difficulties in
the precise and exact observation of it; that wee may Well
account this inquiry after the longitude of places, to be one of
those things whereof wee must be content to be ignorant, & rather
to gesse at it in Grosse, then in vaine to striue for exactnesse,
which is the cause why the tables of the longitude and latitude
of Citties, though they many times agree in the latitude, doe yet
for the most part very much differ in the Longitude.

6 The sixth Distinction is by the Length or shortnesse of the Day
in Summer time in seuerall Quarters of the earth. And this
diuision is by Climates ([Greek: chlimata]) which are seuerall
spaces of the earth contained betweene two Paralells, in the
which the longest day in Summer excedes that in another Paralell
by halfe an Houre. There is a greate deale of Confusion and
difference betweene the late and ancient Geographers about the
distinction and diuers reckonings of the Climats. It is not
worth the labour to recount theire opinions and Calculations:
thus much is plaine, and easie to bee knowne. There are 24.
Climats in which the Day encreaseth by halfe houres from 12.
houres to 24. There are likewise 6. Climats in which the day
encreaseth by moneths, from one moneth to sixe that is halfe a
yeare. Vnder the Aequator the day is alwayes twelue houres longe,
but as you goe from it towards the Pole, the Day lengthens still
till it comes to a day halfe a yeare long.[3] Now in what degrees
of latitude euery on of these Climats beginne and end, shall
