i. npURN the Globe round its Axis,

X till the given Place lies exactlyunder the (Eastern Side of the Brass) Me-ridian} then that Degree upon the Meri-dian, which is directly over it, is the Lati-tude: which is accordingly North or South,as it lies in the Northern or Southern He-misphere. The Globe remaining in thesame Position.

That Degree upon the Equator which iscut by the Brazen Meridian is the Longi-tude required, from the first Meridian uponthe Globe. If the Longitude is countedboth Ways from the first Meridian upon theGlobe, then we are to consider, whether thegiven Place lies Easterly or Westerly fromthe first Meridian, and the Longitude mustbe expressed accordingly.
