to be seene in it, and also for that I am in this science 

 little expert : Yet to remedy in part this difficulty, it is 

 necessary to declare to your Lordship my intent, with 

 which I trust you shall perceive in this Card part of 

 your desire, if, for that I cannot expresse mine intent, 

 with my declaration I doe not make it more obscure. 



First, your Lordship knoweth that the Cosmographers 

 have divided the earth by 360 degrees in latitude, and 

 as many in longitude, under the which is comprehended 

 all the roundnes of the earth : the latitude being divided 

 into foure quarters, ninetie degrees amount to every 

 quarter, which they measure by the altitude of the Poles, 

 that is the North and South starres, being from the line 

 Equinoctiall till they come right under the North starre 

 the said ninetie degrees : and as much from the sayd 

 line Equinoctiall to the South starre be other ninety 

 degrees. And as much more is also from either of the 

 sayd starres agayne to the Equinoctiall. Which imagined 

 to bee round, is soone perceived thus, 360 degrees of 

 latitude to be consumed in the said foure quarters of 

 ninetie degrees a quarter : so that this latitude is the 

 measure of the worlde from North to South, and from 

 South to North. And the longitude, in which are also 

 counted other 360, is counted from West to East, or 

 from East to West, as in the Card is set. 



The sayd latitude your Lordship may see marked To know the 

 and divided in the ende of this Card on the left hand : latltudes - 

 so that if you would know in what degrees of latitude 

 any region or coast standeth, take a compasse, and set 

 the one foot of the same in the Equinoctial line right 

 against the said region, & apply the other foote of the 

 compasse to the said region or coast, & then set the 

 sayd compasse at the end of the Card, where the 

 degrees are divided. And the one foote of the compasse 

 standing in the line Equinoctial, the other will shew 

 in the scale the degrees of altitude or latitude that the 

 said region is in. Also the longitude of the world I 

 have set out in the nether part of the Card, conteining
