Thou hast here (gentle reader) a true hydrographical description of so much of the world as hath beene hetherto discouered and is comne to our knowledge. which we haue in such sort performed, yt all places herein set downe, haue the same positions and distances that they haue in the globe, being therin placed in same longitudes and latitudes which they haue in this chart; which by the ordinarie sea chart can in no wise be performed. The way to finde the position, or course from any place to other herein described, differeth nothing from that which is vsed in the ordinarie sea chart. But to finde the distance; if both places haue the same latitude, see how many degrees of the meridian taken at that latitude are contayned betweene the two places, for so many score leagues is the distaunce. If they differ in latitude, see howe many degrees of the meridian taken about the midst of that difference are conteyned betweene; them and so many score leagues is the distaunce.
