As the proper Distance upon the Rhumb is to the Difference of Longitude;
So is the Radius to the Sine of the Rhumb from the Meridian.

As the proper Distance upon the Rhumb is to the Difference of Longitude;
So is the Radius to the Sine of the Rhumb from the Meridian.
Thus, if one of the Places lay in the Latitude of 50 degr. and the other in a greater Latitude, but unknown; the Dif∣ference of Longitude between them 5 ½ degr. and their pro∣per Distance upon the Rhumb 6 degr. the Inclination of the Rhumb to the Meridian which leadeth from one Place to the other will be found to be 33 degr. 45 min. that is the N. E. by N. Point.
